  The Exchange Offer (as defined) and withdrawal rights will expire at 5:00
p.m., New York City time, on      , 1998 (as such date may be extended, the
"Expiration Date").
 
  The GSI Group, Inc., a Delaware corporation (the "Company"), hereby offers,
upon the terms and subject to the conditions set forth in this Prospectus, as
it may be amended and supplemented from time to time (this "Prospectus"), and
the accompanying Letter of Transmittal (the "Letter of Transmittal," and
together with the Prospectus, the "Exchange Offer"), to exchange an aggregate
of up to $100,000,000 principal amount of its 10 1/4% Senior Subordinated Notes
due 2007 (the "New Notes"), which have been registered under the Securities Act
of 1933, as amended (the "Securities Act"), pursuant to a Registration
Statement of which this Prospectus is a part, for an identical principal amount
of its outstanding 10 1/4% Senior Subordinated Notes due 2007 (the "Old Notes")
(the Old Notes and the New Notes are collectively referred to herein as the
"Notes") of the Company from the holders thereof in integral multiples of
$1,000. See "The Exchange Offer."
 
  The Company will accept for exchange any and all Old Notes that are validly
tendered prior to 5:00 p.m., New York City time, on the Expiration Date.
Tenders of Old Notes may be withdrawn at any time prior to 5:00 p.m., New York
City time, on the Expiration Date, otherwise such tenders are irrevocable. The
Exchange Offer is not conditioned upon any minimum principal amount of the Old
Notes being tendered for exchange. However, the Exchange Offer is subject to
certain customary conditions and to the terms and provisions of the
Registration Rights Agreement, dated as of November 5, 1997 (the "Registration
Rights Agreement"), among the Company, David Manufacturing Co. ("DMC") and
Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated and
Morgan Stanley & Co., Incorporated (the "Initial Purchasers"). See "The
Exchange Offer" and "Registration Rights."

THAT SHOULD BE CONSIDERED BY HOLDERS IN EVALUATING THE EXCHANGE OFFER.
 
                                  -----------
 
 THE  NOTES HAVE  NOT  BEEN  APPROVED OR  DISAPPROVED  BY  THE SECURITIES  AND
   EXCHANGE COMMISSION  OR  ANY  STATE  SECURITIES  COMMISSION  NOR  HAS THE
    SECURITIES AND  EXCHANGE COMMISSION OR ANY STATE  SECURITIES COMMISSION
      PASSED  UPON THE  ACCURACY  OR  ADEQUACY  OF  THIS PROSPECTUS.  ANY
       REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.
 
                                  -----------
 
                  The date of this Prospectus is       , 1998
<PAGE>
 
  An aggregate of $100 million principal amount of Old Notes were sold by the
Company to the Initial Purchasers on November 5, 1997 (the "Issue Date")
without registration under the Securities Act, in reliance upon exemptions
therefrom, pursuant to a Purchase Agreement, dated October 30, 1997 (the
"Purchase Agreement"), among the Company and the Initial Purchasers. The
Initial Purchasers subsequently resold the Old Notes in reliance on Rule 144A
under the Securities Act ("Rule 144A") and Regulation S under the Securities
Act ("Regulation S"). The Company and the Initial Purchasers also entered into
the Registration Rights Agreement, pursuant to which the Company granted
certain registration rights for the benefit of the holders of the Old Notes.
 
  The Old Notes were, and the New Notes will be, issued under the Indenture,
dated as of November 1, 1997 (the "Indenture"), between the Company and
LaSalle National Bank, as trustee (in such capacity, the "Trustee"). As of the
date of this Prospectus, there are $100,000,000 aggregate principal amount of
Old Notes outstanding. The form and terms of the New Notes will be identical
in all material respects to the form and terms of the Old Notes, except that
(i) the New Notes have been registered under the Securities Act and,
therefore, will not bear legends restricting the transfer thereof, (ii)
holders of New Notes will not be entitled to any increase in the interest rate
("Additional Interest") thereon pursuant to certain circumstances under the
Registration Rights Agreement and (iii) holders of New Notes will no longer be
entitled to certain other rights under the Registration Rights Agreement.
 
  Interest on the New Notes is payable semiannually in arrears on each May 1
and November 1, commencing May 1, 1998. Holders whose Old Notes are accepted
for exchange will have the right to receive interest accrued thereon from the
date of their original issuance or the last interest payment date, as
applicable, to, but not including, the date of issuance of the New Notes, such
interest to be payable with the first interest payment on the New Notes.
Interest on the Old Notes accepted for exchange will cease to accrue on the
day prior to the issuance of the New Notes. The New Notes will mature on
November 1, 2007. See "Description of the New Notes--Maturity, Interest and
Principal."
 
  The New Notes will be redeemable at the option of the Company, in whole or
in part, at any time on or after November 1, 2002, at the redemption prices
set forth herein, plus accrued and unpaid interest thereon, if any, to the
date of redemption. In addition, on or prior to November 1, 2000, the Company
may redeem up to 35% of the originally issued aggregate principal amount of
the Notes, at a redemption price of 110.25% of the principal amount thereof,
plus accrued and unpaid interest thereon, if any, to the redemption date, with
the net proceeds of an Equity Offering (as defined herein); provided, that not
less than $65.0 million in aggregate principal amount of New Notes is
outstanding immediately after giving effect to such redemption. Following the
occurrence of a Change of Control (as defined herein), the Company will be
required to make an offer to repurchase the New Notes at a price equal to 101%
of the principal amount thereof, plus accrued and unpaid interest thereon, if
any, to the date of purchase. See "Description of the New Notes--Optional
Redemption" and "--Change of Control."
 
  The New Notes will represent unsecured senior subordinated obligations of
the Company and will be subordinated in right of payment to all existing and
future Senior Indebtedness (as defined herein) of the Company. The New Notes
also will be fully and unconditionally guaranteed (the "DMC Guarantee") on an
unsecured senior subordinated basis by DMC, which is a wholly-owned subsidiary
of the Company. As of September 30, 1997, on a pro forma basis after giving
effect to the offering of the Old Notes (the "Offering"), the application of
the net proceeds therefrom and the DMC Acquisition (as defined herein), the
Company would have had approximately $6.9 million of Senior Indebtedness
outstanding. In addition, at September 30, 1997, on a pro forma basis after
giving effect to the Offering, the application of the net proceeds therefrom
and the DMC Acquisition, the Company's subsidiaries would have had
approximately $6.0 million of indebtedness to which holders of the Notes would
have been effectively subordinated.
 
  The New Notes are being offered hereby in order to satisfy certain
obligations of the Company contained in the Registration Rights Agreement. The
Company is making the Exchange Offer in reliance on the position of
 
                                       i
<PAGE>
 
the staff of the Securities and Exchange Commission (the "Commission") as set
forth in certain interpretive letters addressed to third parties in other
transactions. However, the Company has not sought its own interpretive letter
and there can be no assurance that the staff of the Commission would make a
similar determination with respect to the Exchange Offer as it has in such
interpretive letters to third parties. Based on these interpretations by the
staff of the Commission, the Company believes that New Notes issued pursuant
to the Exchange Offer in exchange for Old Notes may be offered for resale,
resold and otherwise transferred by a holder (other than (i) a broker-dealer
who purchased Old Notes directly from the Company for resale pursuant to Rule
144A or any other available exemption under the Securities Act, (ii) an
"affiliate" of the Company within the meaning of Rule 405 under the Securities
Act or (iii) a broker-dealer who acquired the Old Notes as a result of market-
making or other trading activities), without further compliance with the
registration and prospectus delivery provisions of the Securities Act,
provided, that such holder is acquiring the New Notes in the ordinary course
of business and is not participating, and has no arrangement or understanding
with any person to participate, in a distribution (within the meaning of the
Securities Act) of the New Notes. Holders wishing to accept the Exchange Offer
must represent to the Company, as required by the Registration Rights
Agreement, that such conditions have been met. Any holder of Old Notes who is
not able to rely on the interpretations of the staff of the Commission set
forth in the above-mentioned interpretive letters must comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with any sale of such Old Notes, unless such sale is made pursuant
to an exemption from such requirements. See "The Exchange Offer-- Resales of
New Notes."
 
  Each broker-dealer who receives New Notes for its own account pursuant to
the Exchange Offer must acknowledge that it acquired the Old Notes for its own
account as a result of market-making activities or other trading activities
and must agree that it will deliver a prospectus meeting the requirements of
the Securities Act in connection with any resale of such New Notes. The Letter
of Transmittal states that by so acknowledging and by delivering a prospectus,
a broker-dealer will not be deemed to admit that it is an "underwriter" within
the meaning of the Securities Act. Based on the position taken by the staff of
the Commission in the interpretive letters referred to above, the Company
believes that broker-dealers who acquired Old Notes for their own accounts as
a result of market-making or other trading activities ("Participating Broker-
Dealers") may fulfill their prospectus delivery requirements with respect to
the New Notes received upon exchange of such Old Notes (other than Old Notes
that represent an unsold allotment from the original sale of the Old Notes)
with a prospectus meeting the requirements of the Securities Act, which may be
the prospectus prepared for an exchange offer so long as it contains a
description of the plan of distribution with respect to the resale of such New
Notes. Accordingly, this Prospectus may be used by a Participating Broker-
Dealer in connection with resales of New Notes received in exchange for Old
Notes where such Old Notes were acquired by such Participating Broker-Dealer
for its own account as a result of market-making or other trading activities.
Subject to certain provisions set forth in the Registration Rights Agreement,
the Company has agreed that this Prospectus may be used by a Participating
Broker-Dealer in connection with resales of such New Notes. See "Plan of
Distribution." However, a Participating Broker-Dealer who intends to use this
Prospectus in connection with the resale of New Notes received in exchange for
Old Notes pursuant to the Exchange Offer must notify the Company, or cause the
Company to be notified, on or prior to the Expiration Date, that it is a
Participating Broker-Dealer. Such notice may be given in the space provided
for that purpose in the Letter of Transmittal or may be delivered to the
Exchange Agent at one of the addresses set forth herein under "The Exchange
Offer--Exchange Agent; Assistance." Any Participating Broker-Dealer who is an
"affiliate" of the Company may not rely on such interpretive letters and must
comply with the registration and prospectus delivery requirements of the
Securities Act in connection with any resale transaction. See "The Exchange
Offer--Resales of New Notes."
 
  In that regard, each Participating Broker-Dealer who surrenders Old Notes
pursuant to the Exchange Offer will be deemed to have agreed, by execution of
the Letter of Transmittal, that, upon receipt of notice from the Company of
the occurrence of any event or the discovery of any fact which makes any
statement contained in this Prospectus untrue in any material respect or which
causes this Prospectus to omit to state a material fact necessary in order to
make the statements contained herein, in light of the circumstances under
which they were
 
                                      ii
<PAGE>
 
made, not misleading or of the occurrence of certain other events specified in
the Registration Rights Agreement, such Participating Broker-Dealer will
suspend the sale of New Notes pursuant to this Prospectus until the Company
has amended or supplemented this Prospectus to correct such misstatement or
omission and has furnished copies of the amended or supplemented Prospectus to
such Participating Broker-Dealer or the Company has given notice that the sale
of the New Notes may be resumed, as the case may be.
 
  The New Notes issued pursuant to this Exchange Offer will be issued in the
form of a Global New Note (as defined herein), which will be deposited with,
or on behalf of, The Depository Trust Company ("DTC") and registered in its
name or in the name of Cede & Co., its nominee. Beneficial interests in the
Global New Note representing the New Notes will be shown on, and transfers
thereof will be effected through, records maintained by DTC and its
participants. Notwithstanding the foregoing, Old Notes held in certificated
form, if any, will be exchanged solely for Certificated New Notes (as defined
herein). After the initial issuance of the Global New Note, Certificated New
Notes will be issued in exchange for interests in the Global New Note only on
the terms set forth in the Indenture. See "Description of the New Notes" and
"Book-Entry, Delivery and Form."
 
  The Company will not receive any proceeds from this offering, but, pursuant
to the Registration Rights Agreement, the Company will bear certain
registration expenses. No underwriter is being utilized in connection with the
Exchange Offer.
 
  THE EXCHANGE OFFER IS NOT BEING MADE TO, NOR WILL THE COMPANY ACCEPT
SURRENDERS FOR EXCHANGE FROM, HOLDERS OF OLD NOTES IN ANY JURISDICTION IN
WHICH THE EXCHANGE OFFER OR THE ACCEPTANCE THEREOF WOULD NOT BE IN COMPLIANCE
WITH THE SECURITIES OR BLUE SKY LAWS OF SUCH JURISDICTION.
 
  THIS PROSPECTUS AND THE RELATED LETTER OF TRANSMITTAL CONTAIN IMPORTANT
INFORMATION. HOLDERS OF OLD NOTES ARE URGED TO READ THIS PROSPECTUS AND THE
RELATED LETTER OF TRANSMITTAL CAREFULLY BEFORE DECIDING WHETHER TO TENDER
THEIR OLD NOTES PURSUANT TO THE EXCHANGE OFFER.

                             AVAILABLE INFORMATION
 
  The Company and DMC have jointly filed a registration statement on Form S-4
(together with any amendments thereto, the "Registration Statement") with the
Commission under the Securities Act with respect to the New Notes and the
related DMC Guarantee. This Prospectus, which constitutes a part of the
Registration Statement, omits certain information contained in the
Registration Statement and reference is made to the Registration Statement and
the exhibits and schedules thereto for further information with respect to the
Company and the New Notes offered hereby. This Prospectus contains summaries
of the material terms and provisions of certain documents and in each instance
reference is made to the copy of such document filed as an exhibit to the
Registration Statement. Each such summary is qualified in its entirety by such
reference.
 
  The Company is not currently subject to the informational requirements of
the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Upon the
effectiveness of the Registration Statement, the Company will be subject to
the reporting requirements of the Exchange Act and the interpretations issued
thereunder by the staff of the Commission. The Registration Statement, such
reports and other information can be inspected and copied at the offices of
the Commission at Room 1024, Judiciary Plaza, 450 Fifth Street, N.W.,
Washington, D.C. 20549, as well as the following regional offices of the
Commission: Seven World Trade Center, Suite 1300, New York, New York 10048;
and Citicorp Center, 500 West Madison Street, Suite 1400, Chicago, Illinois
60661. Copies of such material can be obtained from the Public Reference
Section of the Commission at 450 Fifth Street, N.W., Washington, D.C. 20549 at
prescribed rates. Such material also may be accessed electronically by means
of the Commission's home page on the Internet (http://www.sec.gov).
 
  So long as any of the Old Notes are outstanding, the Company will file with
the Commission, to the extent then permitted by the Commission, the annual
reports, quarterly reports and other documents that the Company would have
been required to file with the Commission pursuant to Sections 13(a) and 15(d)
of the Exchange Act if the Company was subject to such Sections, and the
Company will promptly provide to the Trustee copies of such reports and
documents; provided, however, that if the Company is for any reason unable to
make such filings it will make available, upon request, to any holder of Old
Notes or prospective purchaser of New Notes, the information specified in Rule
144(A)(d)(4) of the Securities Act.
 
                          FORWARD-LOOKING STATEMENTS
 
  Certain statements contained in this Prospectus under "Prospectus Summary,"
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "Business," in addition to certain statements contained
elsewhere in this Prospectus, are "forward-looking statements" within the
meaning of the Private Securities Litigation Reform Act of 1995 and are thus
prospective. Such "forward-looking statements" are subject to risks,
uncertainties and other factors that could cause actual results to differ

                                  THE COMPANY
 
INTRODUCTION
 
  The Company is a leading manufacturer and supplier of agricultural equipment
and services worldwide. The Company believes that it is the largest global
provider of both (i) grain storage bins and related drying and handling systems
and (ii) swine feed storage, feed delivery, confinement and ventilation
systems. The Company also is one of the largest global providers of poultry
feed storage, feed delivery, watering, ventilation, nesting, egg-handling and
hatching systems. The Company markets its agricultural products in
approximately 75 countries through a network of over 1,600 independent dealers
to grain, swine and poultry producers primarily under its GSI(R), AP(TM) and
Cumberland(R) brand names. The Company's current market position in the
industry reflects both the strong, long-term relationships the Company has
developed with its customers as well as the quality and reliability of its
products.
 
  Craig Sloan, the Chief Executive Officer of the Company, founded its current
business in 1972. In 1995, the Company recruited additional management and in
1996, all of the capital stock of the Company was acquired by Mr. Sloan and
certain other executives of the Company. The Company's new management-led
ownership has implemented a growth strategy designed to position the Company as
the premier worldwide manufacturer and supplier of high-quality, cost efficient
grain, swine and poultry systems. In addition to capitalizing on domestic and
international growth opportunities, the Company's new management has focused on
profitability, production efficiencies and cost reductions commenced during
1995. As a result, the Company has experienced rapid growth in recent years.
Net sales and operating income increased from $141.2 million and $4.0 million,
respectively, in 1995 to $178.5 million and $14.1 million, respectively, in
1996, and were $172.0 million and $16.5 million, respectively, for the nine
months ended September 30, 1997. Income from continuing operations (excluding
the write-off of an affiliate receivable) plus interest expense (including
amortization of debt issuance costs), depreciation and amortization ("EBITDA")
increased from $7.9 million in 1995 to $17.6 million in 1996, and was $19.2
million for the nine months ended September 30, 1997. On a pro forma basis
after giving effect to the Offering, the application of the net proceeds
therefrom and the DMC Acquisition, EBITDA would have been $26.9 million for the
twelve months ended September 30, 1997.
 
  The primary users of the Company's grain storage, drying and handling
products are farm operators or commercial businesses, such as the Archer-
Daniels-Midland Company and Cargill, Inc., that operate feed mills, grain
elevators, port storage facilities and commercial grain processing facilities.
The Company believes that its grain storage, drying and handling equipment is
superior to that of its principal competitors on the basis of strength,
durability, reliability, design efficiency and breadth of product offering. The
Company's feeding and ventilation systems are used primarily by growers that
raise swine and poultry, typically on a contract basis for large integrators
such as Murphy Family Farms, Perdue Farms Incorporated and Tyson Foods, Inc.
Because swine and poultry growers are partially compensated by integrators
based on the efficiency with which they convert feed to meat (the "feed-to-meat
ratio"), they seek to purchase systems which minimize the feed-to-meat ratio.
As a result of its proprietary designs, the Company believes that its swine and
poultry systems are the most effective in the industry in serving this customer
objective.
 
  The industry in which the Company operates is characterized both domestically
and internationally by a few large companies, such as the Company, with broad
product offerings and numerous small manufacturers of niche product lines.
Domestically, the Company intends to build on its established presence in the
grain, swine
 
                                       1

and poultry markets. Internationally, the Company intends to capitalize on
growth opportunities arising from still-developing agricultural industries and
favorable trends in the demand for grain, poultry and swine products. The
Company believes that less functionally sophisticated and efficient grain
storage systems used by facilities located outside the U.S. and Western Europe,
which experience relatively high levels of grain spoilage and loss, are
increasingly likely to be replaced by more modern systems. The Company also
believes that the significant economic and population growth occurring in the
Company's international markets will continue to result in consumers devoting
larger portions of their income to improved and higher-protein diets,
stimulating stronger demand for poultry and, to a lesser extent, pork. The
Company believes that it is well-positioned to capture expected increases in
worldwide demand for its products resulting from these industry trends because
of its leading brand names, broad and diversified product lines, strong
distribution network and high-quality products. See "Business--Industry
Overview."
 
COMPANY STRENGTHS
 
  MARKET LEADER. The Company believes that it is the largest global provider of
both (i) grain storage bins and related drying and handling systems and (ii)
swine feed storage, feed delivery, confinement and ventilation systems. The
Company also is one of the largest global providers of poultry feed storage,
feed delivery, watering, ventilation, nesting, egg-handling and hatching
systems. The Company intends to continue to build its market share by
capitalizing on its strong reputation and the growth trends in worldwide demand
for grain, swine and poultry production.
 
  PROVIDER OF FULLY-INTEGRATED SYSTEMS. The Company offers a broad range of
products that permits customers to purchase all of their grain, swine and
poultry production needs from one supplier. The Company believes that providing
fully-integrated systems significantly lowers total production costs and
enhances producer productivity by offering compatible products designed to
promote synergies and achieve maximum operating results. Dealers who purchase
fully-integrated systems also benefit from lower administrative and shipping
costs and the ease of dealing with a single supplier. The Company intends to
maintain its position as a provider of fully-integrated systems by continuing
to offer the most complete line of products available within its markets and by
developing and introducing new products. See "Business--Products."
 
  BRAND NAME RECOGNITION AND REPUTATION FOR QUALITY PRODUCTS AND SERVICE.
Through its manufacturing expertise and experience, the Company has established
recognition in its markets for the GSI(R), AP(TM) and Cumberland(R) brand
names. The Company seeks to protect the reputation for high quality,
reliability and specialized services that are associated with such brand names
through extensive quality control and customer feedback programs. The Company
believes that its reputation and recognized brand names, along with its
extensive distribution network, will assist it in its efforts to further
penetrate both the domestic and international markets in which the Company
operates.
 
  EFFECTIVE AND ESTABLISHED DISTRIBUTION NETWORK. The Company believes that its
development of a highly effective and established distribution network affords
it significant competitive advantages. The Company's distribution network
consists of over 1,600 independent dealers that market the Company's products
in approximately 75 countries throughout the world. The breadth and scope of
the Company's distribution network makes its products readily available in each
of the Company's markets and lowers transportation costs for its customers.
Dealers are carefully selected and trained to ensure high levels of customer
service. In addition, the Company has experienced a very low turnover rate of
its dealers since the Company's inception, which promotes consistency and
stability to customers. See "Business--Product Distribution."
 
  LONG-TERM ALLIANCES WITH CUSTOMERS. The Company has a history of developing
long-term alliances with customers who are market leaders in both the
industries and the geographic markets they serve. The Company works closely
with customers through all stages of product development in order to tailor
products and systems to meet each customer's unique needs, making substitutions
with competitor products more difficult. The
 
                                       2
<PAGE>
 
Company's commitment to product quality, dedication to customer service and
responsiveness to changing customer needs have enabled the Company to develop
and strengthen long-term alliances with its customers. The strength of the
Company's customer relationships are demonstrated by the fact that over 45% of
the Company's 1996 domestic net sales derived from grain equipment were made to
customers who have purchased from the Company for at least 10 years. In
addition, the Company has entered into long-term supply agreements with two of
its largest customers, which arrangements the Company believes are unique in
the industry.
 
  FLEXIBLE MANUFACTURING FACILITIES. The Company's facilities are designed to
be easily reconfigured to adapt to demand changes for any or all of the
Company's products. The Company's primary manufacturing facility, located in
Assumption, Illinois, consists of approximately 675,000 square feet and
operates on a 24-hour basis during peak production periods. The Company's
facilities employ state-of-the-art machines that have enhanced production
efficiency. The Company believes that its current facilities will accommodate
planned production increases as the Company experiences sales growth and
expands into new markets. See "Business--Facilities."
 
  COMPANY OPERATED AND OWNED BY EXPERIENCED MANAGEMENT TEAM. The Company is led
by an experienced management team, the members of which have each worked in the
agricultural products industry for an average of 16 years. Craig Sloan, a
founder and the Chief Executive Officer of the Company, and each of the other
members of the Company's senior management team have invested in the Company
and together own all of its voting common stock. The Company believes that the
agricultural expertise of its management team, coupled with the corporate
culture promoted by a management-owned company, permit it to establish strong
customer relationships and respond quickly to market opportunities. See
"Management--Executive Officers and Directors" and "Ownership of Capital
Stock."
 
BUSINESS STRATEGY
 
  The Company's objective is to capitalize on its strengths through the
implementation of its business strategy, which includes the following principal
elements:
 
  CAPITALIZE ON GROWTH OPPORTUNITIES IN INTERNATIONAL MARKETS. International
sales increased from approximately $36.8 million in 1995 to approximately $55.5
million in 1996, and were approximately $43.5 million in the nine months ended
September 30, 1997. The Company intends to continue to leverage its worldwide
brand name recognition, leading market positions and international distribution
network to capture the significant demand for its products that exists in the
international marketplace. While the Company anticipates that sales will
continue to be generated worldwide, the Company is targeting the Far East,
Latin America and Eastern Europe, where it believes the greatest potential for
significant growth exists. The Company believes that increasing the diversity
of both its customer base and geographic coverage by expanding its
international operations will mitigate the effect of future reductions in
demand within any of its individual product lines, or within a particular
geographic selling region.
 
  ENHANCE GROWTH THROUGH STRATEGIC ACQUISITIONS. The Company will continue to
selectively seek acquisitions with complementary product lines that offer the
opportunity to improve market penetration and profitability through integration
with the Company's existing businesses. The Company believes that the markets
in which it operates include single-product producers who may not be able to
effectively compete against larger, integrated producers, such as the Company,
but which might benefit from economies of scale resulting from a business
combination with the Company. The Company recently acquired all of the capital
stock of DMC, a leading manufacturer and supplier of grain drying and handling
equipment, to complement the Company's grain equipment product line.
 
  CONTINUE DEVELOPMENT OF PROPRIETARY PRODUCT INNOVATIONS. The Company's
research and development efforts focus on the development of new and
technologically advanced products to respond to customer demands, changes in
the marketplace and new technology. The Company employs a strategy of working
closely with its
 
                                       3
<PAGE>
 
customers and capitalizing on existing technology to improve existing products
and develop new value-added products. The Company believes that it has an
impressive record of new product development as is evidenced by its improved
Easy Access doors and Series 2000 dryers for grain bins, its Performer Fan(TM)
line of products for the swine industry, and its patented HI-LO(R) chicken
feeders and Delta Series(TM) turkey feeders. The Company intends to continue to
actively develop product improvements and innovations to more effectively serve
its customers. See "Business--Products."
 
  CONTINUE PROFITABILITY ENHANCEMENTS. The Company plans to continue to
actively manage its business to improve cash flows by containing costs,
selectively expanding production and improving productivity. The Company's past
success in enhancing profitability is evidenced by an EBITDA margin for 1996 of
9.9%, compared to 5.6% for 1995, and an EBITDA margin of 11.1% for the nine
months ended September 30, 1997, compared to 10.3% for the corresponding period
in 1996.
 
DMC ACQUISITION
 
  In furtherance of its business strategy, on November 5, 1997, the Company
acquired all of the capital stock of DMC (the "DMC Acquisition") for
approximately $19.3 million in cash.
 
  DMC is a leading manufacturer and supplier of grain drying and handling
equipment. DMC manufactures equipment at its headquarters in Mason City, Iowa
and maintains six company-owned distribution facilities in Iowa, Nebraska,
Illinois, Arkansas, Indiana and South Dakota. DMC uses this distribution
network to market products to approximately 1,500 domestic and international
dealers. DMC recorded net sales and operating income of $26.0 million and $3.7
million, respectively, for the eleven months ended September 30, 1997.
Approximately 52% of DMC's net sales during such period were derived from
products manufactured by DMC, with the remaining portion derived from products,
including augers, fans, heaters, floor supports and bucket elevators and
conveyors, that were purchased from manufacturers other than the Company.
International sales comprised approximately 13.5% of DMC's net sales for the
eleven months ended September 30, 1997.
 
  The Company believes that the DMC Acquisition has expanded the breadth of the
Company's grain equipment product line and will increase net sales and
operating income. Because the Company manufactures many of the products sold
but not manufactured by DMC, the Company supplies such products to DMC. The
Company will continue to leverage DMC's distribution network to increase sales
of the Company's swine equipment. In addition, the Company believes it can
increase sales of DMC products through dealers in the Company's distribution
network who currently handle products of competitors of DMC.

Resales of New Notes............ The Company is making the Exchange Offer in
                                 reliance on the position of the staff of the
                                 Commission as set forth in certain
                                 interpretive letters addressed to third
                                 parties in other transactions. However, the
                                 Company has not sought its own interpretive
                                 letter and there can be no assurance that the
                                 staff of the Commission would make a similar
                                 determination with respect to the Exchange
                                 Offer as it has in such interpretive letters
                                 to third parties. Based on these
                                 interpretations by the staff of the
                                 Commission, the Company believes that New
                                 Notes issued pursuant to the Exchange Offer
                                 in exchange for Old Notes may be offered for
                                 resale, resold and otherwise transferred by a
                                 holder (other than (i) a broker-dealer who
                                 purchased Old Notes directly from the Company
                                 for resale pursuant to Rule 144A or any other
                                 available exemption under the Securities Act,

                                 Securities Act; provided, that such holder is

                                 (within the meaning of the Securities Act) of

Registration Rights............. In the event that applicable law or
                                 Commission policy does not permit the
                                 Company to effect the Exchange Offer, or
                                 if certain holders of the Old Notes are
                                 not permitted to participate in, or do
                                 not receive the benefit of the Exchange
                                 Offer, the Registration Rights Agreement
                                 provides that the Company will use its
                                 best efforts to cause to become effective
                                 a shelf registration statement (the
                                 "Shelf Registration Statement") with
                                 respect to the resale of the Old Notes
                                 and to keep such Shelf Registration
                                 Statement effective until two years after
                                 the Issue Date or such shorter period
                                 ending when all the Old Notes have been
                                 sold thereunder or cease to be
                                 outstanding. The interest rate on the Old
                                 Notes is subject to increase under
                                 certain circumstances if the Company is
                                 not in compliance with its obligations
                                 under the Registration Rights Agreement.

(1) In December 1995, the Company signed an agreement to sell the working
    capital and fixed assets of its Heritage Vinyl Division. In January 1996,
    the sale was closed. The Company's 1994 financial statements were restated
    to reflect this discontinued operation. See Note 3 to Consolidated
    Financial Statements.

(2) Pro Forma to give effect to the Offering, the application of the net
    proceeds therefrom and the DMC Acquisition. See "Business--DMC
    Acquisition," "Use of Proceeds" and "Capitalization."
(3) The write-off of the affiliate receivable resulted from a significant
    customer, who is an affiliate of the Company, ceasing distribution
    operations and selling its only division in December 1995. The write-off of
    the affiliate receivable represents the portion of the remaining receivable
    due that was not collectible. See Note 11 to Consolidated Financial
    Statements.
(4) Adjusted to give effect to the Offering, the application of the net
    proceeds therefrom and the DMC Acquisition, the Company would have reported
    an extraordinary gain in connection with an early extinguishment of certain
    former stockholders' notes.
(5) The Company currently operates as a Subchapter "S" corporation and,
    accordingly, is not subject to federal income taxation for the periods for
    which financial information has been presented herein.
(6) EBITDA represents income from continuing operations (excluding the write-
    off of an affiliate receivable) plus interest expense (including
    amortization of debt issuance costs), depreciation and amortization. EBITDA
    is presented here to provide additional information about the Company's
    ability to meet its future debt service, capital expenditure and working
    capital requirements. EBITDA is not a measure of financial performance
    under generally accepted accounting principles ("GAAP") and should not be
    considered as an alternative either to net income as an indicator of the
    Company's operating performance, or to cash flows as a measure of the
    Company's liquidity.
(7) The ratio of earnings to fixed charges is expressed as the ratio of fixed
    charges plus pretax earnings to fixed charges. Fixed charges include
    interest on borrowings, amortization of deferred financing costs and the
    interest portion of rent expense. Earnings were insufficient to cover fixed
    charges for the year ended December 31, 1995 by $1.8 million.
(8) Total stockholders' deficit at December 31, 1996 resulted from a management
    buyout of the Company's capital stock in June 1996. The Company purchased
    its capital stock from selling shareholders using cash and notes. In order
    to fund a portion of the cash payments made by the Company, the Company
    obtained a $4.0 million term loan. See "Certain Relationships and Related
    Transactions--Management Buyout" and Note 6 to Consolidated Financial
    Statements.

                                 RISK FACTORS
 
  Prospective investors should carefully consider, among other matters, the
following in connection with a decision to tender their Old Notes in the
Exchange Offer. The risk factors set forth below are generally applicable to
the Old Notes as well as the New Notes.
 
LEVERAGE; ABILITY TO SERVICE INDEBTEDNESS
 
  The Company is highly leveraged. As of September 30, 1997, on a pro forma
basis after giving effect to the Offering, the application of the net proceeds
therefrom and the DMC Acquisition, the Company would have had approximately
$102.0 million (net of an unamortized discount of $769,000 on the Notes) of
indebtedness outstanding. Subject to certain restrictions, exceptions and
financial tests set forth in the Indenture and the New Credit Agreement (as
defined herein), the Company also may incur additional indebtedness in the
future. The degree to which the Company is leveraged could have important
consequences to the holders of the Notes, including, but not limited to, the
following: (i) a substantial portion of the Company's cash flow from
operations will be required to be dedicated to debt service and will not be
available to the Company for its operations; (ii) the Company's ability to
obtain additional financing in the future for acquisitions, capital
expenditures, working capital or general corporate purposes could be limited;
(iii) the Company will have increased vulnerability to adverse general
economic and industry conditions; and (iv) the Company may be vulnerable to
higher interest rates because borrowings under certain of its credit
arrangements are at variable rates of interest. The Company's ability to make
scheduled payments of principal of, to pay interest on or to refinance its
indebtedness (including the Notes) depends on its future performance and
financial results, which, to a certain extent, are subject to general
economic, financial, competitive, legislative, regulatory and other factors
beyond the Company's control. There can be no assurance that the Company's
business will generate sufficient cash flow from operations or that future
working capital borrowings will be available in an amount sufficient to enable
the Company to service its indebtedness, including the Notes, or make
necessary capital expenditures. See "Description of the New Credit Agreement"
and "Description of the New Notes."
 
SUBORDINATION
 
  The payment of principal, premium, if any, and interest on the Notes will be
subordinated in right of payment to the prior payment in full of all existing
and future Senior Indebtedness of the Company, including indebtedness incurred
under the New Credit Agreement. As of September 30, 1997, on a pro forma basis
after giving effect to the Offering, the application of the net proceeds
therefrom and the DMC Acquisition, the Company would have had approximately
$6.9 million of Senior Indebtedness outstanding ($4.1 million of which was in
the form of performance bonds and guarantees) and the ability (subject to
certain conditions) to incur an additional $40.0 million of Senior
Indebtedness under the New Credit Agreement. The Notes also will be
effectively subordinated to all existing and future indebtedness of the
Company's subsidiaries. As of September 30, 1997, on a pro forma basis after
giving effect to the Offering, the application of the net proceeds therefrom
and the DMC Acquisition, the Company's subsidiaries would have had
approximately $6.0 million of indebtedness to which holders of the Notes would
have been effectively subordinated. Subject to certain restrictions,
exceptions and financial tests set forth in the Indenture and the New Credit
Agreement, the Company also may incur additional indebtedness in the future
that ranks prior to claims of holders of the Notes. See "Description of the
New Notes--Certain Covenants--Limitation on Indebtedness."
 
  The subordination provisions of the Indenture will provide that, upon any
payment or distribution of the Company's assets to creditors upon any
dissolution, winding-up, insolvency, bankruptcy, receivership, liquidation,
reorganization or other proceedings relating to the Company, whether voluntary
or involuntary, holders of the Senior Indebtedness will be entitled to receive
payment in full of all amounts due thereon before the holders of Notes will be
entitled to receive any payment with respect to the Notes. In the event of any
default in the payment in respect of certain Senior Indebtedness, no payment
with respect to the Notes may be made by the Company unless and until such
default has been cured or waived. See "Description of the New Notes--
Subordination."
 
 
                                      13
<PAGE>
 
  The DMC Guarantee will be subordinated to all future guarantees by DMC of
Senior Indebtedness of the Company and any other Guarantor Senior Indebtedness
(as defined herein). As of September 30, 1997, DMC has $     million in
aggregate principal amount of Guarantor Senior Indebtedness outstanding, all
of which ranked senior in right of payment to the DMC Guarantee.
 
RESTRICTIONS IMPOSED BY INDEBTEDNESS
 
  The New Credit Agreement and the Indenture contain covenants that, among
other things and subject to certain exceptions, restrict the ability of the
Company to incur additional indebtedness, pay dividends, prepay subordinated
indebtedness, dispose of certain assets, create liens and make certain
investments or acquisitions and otherwise restrict corporate activities. In
addition, under the New Credit Agreement, the Company is required to satisfy
specified financial covenants, including maintenance of a minimum EBITDA, a
fixed charge coverage ratio and ratio of total debt to EBITDA. The ability of
the Company to comply with such provisions may be affected by events beyond
the Company's control. The breach of any of these covenants could result in a
default under the New Credit Agreement. In the event of any such default,
depending on the actions taken by the lenders under the New Credit Agreement,
such lenders could elect to declare all amounts borrowed under the New Credit
Agreement, together with accrued interest, to be due and payable. A default
under the New Credit Agreement or the instruments governing the Company's
other indebtedness could constitute a cross-default under the Indenture and
any instruments governing the Company's other indebtedness, and a default
under the Indenture could constitute a cross-default under the New Credit
Agreement and any instruments governing the Company's other indebtedness. See
"Description of the New Credit Agreement" and "Description of the New Notes."
 
AGRICULTURAL INDUSTRY; SEASONALITY
 
  The agricultural industry is cyclical and subject to fluctuation. The
Company's sales of grain storage bins and drying and handling equipment have
historically been affected by feed and grain prices, acreage planted, crop
yields, demand, government policies, government subsidies, levels of export
and other factors beyond the Company's control. Weather conditions also can
adversely impact the agricultural industry and delay planned construction
activity, resulting in fluctuating demand for the Company's grain equipment
and delayed or lost revenues. Increases in feed and grain prices have in the
past resulted in a decline in sales of feeding, watering and ventilation
systems, although these same conditions have tended to improve sales of grain
storage bins. The Company's sales of production equipment for swine and
poultry producers have been affected by the level of construction activity by
such producers, which is affected by feed prices and domestic and
international demand for pork and poultry. Future declines in grain prices may
result in decreased grain production and could have a material adverse effect
on sales of the Company's grain storage, drying and handling products.
Declines in domestic or international demand for swine or poultry could have a
material adverse effect on the Company's sales of swine or poultry production
equipment. In addition, general downturns in the farm sector could have a
material adverse effect on the Company's business, financial condition and
results of operations. See "Business--Industry Overview."
 
  Events beyond the control of the Company, such as an outbreak of disease in
swine or poultry, may result in decreased production of swine and poultry in
local markets or generally. For example, a recent outbreak of hog cholera has
resulted in the destruction or scheduled destruction of approximately half of
the swine population in The Netherlands and in Taiwan in an effort to contain
the spread of the disease. Moreover, Belgium and Spain have ordered the
selective destruction of swine for the same purpose. The public perception of
health risks (such as salmonella food poisoning) associated with poultry and
swine products may result in reduced consumption of these products. Crop
diseases could affect grain production in local markets or generally. Any of
these events could have a material adverse effect on the Company's business,
financial condition and results of operations.
 
  Sales of agricultural equipment are seasonal, with farmers traditionally
purchasing grain storage bins in the summer and fall in conjunction with the
harvesting season, and swine and poultry producers purchasing equipment during
prime construction periods in the spring, summer and fall. The Company's net
sales and net
 
                                      14
<PAGE>
 
income have historically been lower during the first and fourth fiscal
quarters as compared to the second and third quarters. In 1996, the Company
generated approximately 26% and 36% of its net sales and 32% and 52% of its
operating income in the second and third fiscal quarters, respectively.
Consequently, results for the nine months ended September 30, 1997 are not
necessarily indicative of results to be expected for the full year. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
 
COMPETITION
 
  The market for the Company's products is competitive. Domestically and
internationally, the Company competes with a variety of manufacturers and
suppliers that offer a limited number of the products offered by the Company.
The Company believes that only one of its competitors, CTB International
Corp., offers products across most of the Company's product lines. Recent
trends towards consolidation in the agricultural industry have intensified
competition. Competition is based on the price, value, reputation, quality and
design of the products offered and the customer service provided by
manufacturers and dealers of the products. Although the Company believes that
it is competitive in all of these categories, there can be no assurance that
the Company will remain competitive in general or in any particular area of
its business. To the extent that the Company's competitors provide more
innovative and/or higher quality products, better designed products, better
pricing or offer better customer service through their distributors and
dealers, the Company's ability to compete could be adversely affected, which
could have a material adverse effect on the Company's business, financial
condition and results of operations. Independent dealers who market, sell and
install the Company's products may also market, sell and install competing
product lines. There can be no assurance that dealers will continue to handle,
or actively market, the Company's products. See "Business--Competition."
 
CONTROL BY PRINCIPAL STOCKHOLDERS; POTENTIAL CONFLICTS OF INTEREST
 
  The Company's senior management team owns all of the outstanding voting
stock of the Company. See "Ownership of Capital Stock." In addition, these
individuals are parties to a voting agreement that requires a majority vote by
the holders of the Company's voting stock to approve certain matters affecting
the Company. See "Certain Relationships and Related Transactions--Management
Buyout--Stockholder Agreements." As a result, these individuals have the
ability to control all fundamental matters affecting the Company, including
the merger of the Company, the sale of all or substantially all of the
Company's assets and the future issuance of any securities of the Company.
 
  Certain decisions concerning the operations or financial structure of the
Company may present conflicts of interest between the Company's stockholders
and the holders of the Notes. For example, if the Company encounters financial
difficulties or is unable to pay its debts as they become due, the interests
of the Company's stockholders might conflict with those of the holders of the
Notes. The Company's stockholders also may have an interest in pursuing
acquisitions, divestitures, financings or other transactions that could
enhance their equity investment, even though such transactions might involve
risk to the holders of the Notes. Because the Company's senior management team
is able to control the management policy of the Company, any such conflict of
interest may be resolved in favor of the Company's stockholders to the
detriment of the holders of the Notes.
 
DEPENDENCE ON KEY PERSONNEL
 
  The Company is dependent upon a number of key executive officers,
particularly Craig Sloan, Chief Executive Officer, Jorge Andrade, President
and Chief Operating Officer, and John W. Funk, Chief Financial Officer,
Secretary, Treasurer and General Counsel, as well as the Presidents of certain
of the Company's divisions. See "Management--Executive Officers and
Directors." The Company has entered into employment agreements with Messrs.
Sloan, Andrade and Funk each of whom are covered by key-man life insurance
policies, the proceeds of which may be used to repurchase their shares of the
Company's capital stock under certain circumstances. See "Management--
Employment Agreements" and "Certain Relationships and Related Transactions--
Management Buyout--Stockholder Agreements." There can be no assurance that the
Company
 
                                      15
<PAGE>
 
will be able to retain its key executive officers or that it will be able to
attract or retain other skilled management personnel in the future. The loss
of the services of any of the Company's key personnel, or the inability to
attract and retain additional qualified personnel, could have a material
adverse effect on the Company's business, financial condition and results of
operations.
 
RAW MATERIALS PRICE VOLATILITY
 
  The principal raw materials used by the Company in the manufacture of its
products, including steel, can be subject to significant price fluctuations.
The Company has no long-term supply contracts for such raw materials. While
the selling prices of the Company's products tend to increase or decrease over
time with the cost of raw materials, such changes may not occur simultaneously
or to the same degree. There can be no assurance that the Company will be able
to pass any increases in raw material costs through to its customers in the
form of price increases. Significant increases in the price of raw materials,
if not offset by product price increases, could have a material adverse effect
on the Company's profitability. See "Business--Raw Materials."
 
RISKS ASSOCIATED WITH ACQUISITIONS
 
  As part of its business strategy, the Company plans to make strategic
acquisitions. In pursuing this acquisition strategy, the Company faces risks
commonly encountered with growth through acquisitions. These risks include
incurring significantly higher than anticipated capital expenditures and
operating expenses, failing to assimilate the operations and personnel of
acquired businesses, losing customers, entering markets in which the Company
has no or limited experience, disrupting the Company's ongoing business and
dissipating the Company's management resources. Realization of the anticipated
benefits of a strategic acquisition may take several years or may not occur at
all. There can be no assurance that the Company will be successful in
overcoming these risks or any other problems encountered with acquisitions. To
the extent that the Company does not successfully avoid or overcome these
risks or problems related to acquisitions, the Company's business, financial
condition and results of operations could be adversely affected. Future
acquisitions also may have a significant impact on the Company's financial
position and results of operations, and could cause substantial fluctuations
in the Company's quarterly and yearly results of operations. Although the
Company will continue to evaluate potential acquisitions, there can be no
assurances that the Company will be successful in effecting any acquisitions
in the future. See "Business--Business Strategy" and "Business--DMC
Acquisition."
 
INTERNATIONAL OPERATIONS; EXPOSURE TO FOREIGN CURRENCY RISK
 
  As part of its business strategy, the Company plans to pursue international
opportunities for growth. International operations generally are subject to
various risks that are not present in domestic operations, including
restrictions on dividends, restrictions on repatriation of funds, unexpected
changes in tariffs and other trade barriers, difficulties in staffing and
managing foreign operations, political instability, fluctuations in currency
exchange rates, reduced protection for intellectual property rights in some
countries, seasonal reductions in business activity and potentially adverse
tax consequences, any of which could adversely impact the Company's
international operations. As the Company expands its operations
internationally, its exposure to such foreign risks will be amplified. There
can be no assurance that one or more of the above-mentioned risks will not
have a material adverse effect on the Company's future international
operations and, consequently, on the Company's business, financial condition
and results of operations. See "Business--Business Strategy" and "Business--
Product Distribution."
 
  The Company currently manufactures or purchases substantially all of its
products in the U.S. and derived approximately 31% of its net sales in 1996
from foreign countries. The production costs, profit margins and competitive
position of the Company are affected by the strength of the U.S. dollar
relative to the strength of the currencies in countries where its products are
sold. The Company's results of operations and financial condition may be
adversely affected by fluctuations in foreign currencies because, for example,
such fluctuations may negatively impact the purchasing power of the Company's
foreign customers and make the Company's products
 
                                      16
<PAGE>
 
less competitive compared to locally-produced products. In addition, the
Company's results of operations and financial condition may also be negatively
impacted by translations of the financial statements of the Company's foreign
subsidiaries from local currencies into U.S. dollars.
 
  The Company enters into foreign currency forward exchange contracts on a
limited basis. Such contracts generally are entered into with respect to
significant outstanding accounts receivable denominated in foreign currencies
for which timing of the receipt of payment can be reasonably estimated. Such
hedging activities are intended to reduce the risk that eventual net dollar
inflows resulting from the sale of products to foreign customers will be
adversely affected by changes in foreign currency exchange rates. Although the
Company seeks to enter into foreign exchange contracts which generally offset
gains and losses on the assets and liabilities being hedged, no assurances can
be given that such hedging activities will not result in losses which will
have an adverse effect on the Company's financial condition or results of
operations.
 
GOVERNMENT REGULATION AND POLICY
 
  Domestic and foreign political developments and government regulations and
policies, including, without limitation, import/export quotas, government
subsidies and reserve programs, directly affect the agricultural industry in
the United States and abroad and thereby indirectly affect the Company's
business. Foreign trade embargoes and import quotas have in the past reduced
U.S. exports of grain, swine and poultry, adversely affecting the Company's
sales. The application or modification of existing laws, regulations or
policies or the adoption of new laws, regulations or policies could have an
adverse effect on the Company's business.
 
REGULATORY AND ENVIRONMENTAL MATTERS
 
  Like other manufacturers, the Company is subject to a broad range of
federal, state, local and foreign laws and requirements, including those
governing discharges to the air and water, the handling and disposal of solid
and hazardous substances and wastes, the remediation of contamination
associated with releases of hazardous substances at the Company's facilities
and offsite disposal locations, workplace safety and equal employment
opportunities. Expenditures made by the Company to comply with such laws and
requirements historically have not been material.
 
  Governmental authorities have the power to enforce compliance with such laws
and regulations and violators may be subject to penalties, injunctions or
both. Third parties may also have the right to enforce compliance with such
laws and regulations. Like most other industrial concerns, the Company's
manufacturing operations entail some risk of future noncompliance with
environmental regulations and there can be no assurance that material costs or
liabilities will not be incurred by the Company as a result thereof. It is
also possible that other developments, such as additional or increasingly
strict requirements of laws and regulations of these types and enforcement
policies thereunder, could significantly increase the Company's costs of
operations. See "Business--Regulatory and Environmental Matters."
 
PRODUCT LIABILITY RISK
 
  Products sold by the Company may expose it to potential liabilities for
personal injury or property damage claims relating to the use of such
products. Although product liability claims historically have not had a
material adverse effect upon the Company, there can be no assurance that the
Company will not be subject to or incur liability for such claims in the
future. While the Company maintains third-party product liability insurance
that it believes to be adequate, there can be no assurance that the Company
will not experience claims in excess of its insurance coverage, or claims that
ultimately are not covered by insurance. There can also be no assurance that
such insurance will continue to be available on economically reasonable terms.
A significant claim that is uninsured or partially insured could result in
loss or deferral of revenues, diversion of resources or damage to the
Company's reputation, any of which could have a material adverse effect on the
Company's business, financial condition and results of operations. See
"Business--Product Liability and Legal Proceedings."
 
 
                                      17
<PAGE>
 
FRAUDULENT CONVEYANCE
 
  The Company believes that the indebtedness represented by the Notes, and DMC
believes the indebtedness represented by the Guarantee, are being incurred for
proper purposes and in good faith, and that, based on present forecasts, asset
valuations and other financial information, the Company and DMC are solvent,
will have sufficient capital for carrying on their businesses and will be able
to pay their debts as they mature. Notwithstanding these beliefs, however,
under federal or state fraudulent transfer laws, if a court of competent
jurisdiction in a suit by an unpaid creditor or a representative of creditors
(such as a trustee in bankruptcy or a debtor-in-possession) were to find that
the Company or DMC did not receive fair consideration (or reasonably
equivalent value) for incurring the Notes or the Guarantee, as the case may
be, and at the time of the incurrence of such indebtedness, the Company or DMC
were insolvent, were rendered insolvent by reason of such incurrence, were
engaged in a business or transaction for which their remaining assets
constituted unreasonably small capital, intended to incur, or believed that
they would incur, debts beyond their ability to pay such debts as they
matured, or that the Company or DMC intended to hinder, delay or defraud their
creditors, then such court could, among other things, (i) void all or a
portion of the Company's obligations to the holders of the Notes or DMC's
obligations under the Guarantee, the effect of which would be that the holders
of the Notes may not be repaid in full, (ii) recover all or a portion of the
payments made to holders of the Notes and/or (iii) subordinate the Company's
or DMC's obligations to the holders of the Notes to other existing and future
indebtedness of the Company or DMC, as the case may be, to a greater extent
than would otherwise be the case, the effect of which would be to entitle such
other creditors to be paid in full before any payment could be made on the
Notes. The measure of insolvency for purposes of the foregoing will vary
depending upon the law of the relevant jurisdiction. Generally, however, a
company would be considered insolvent for purposes of the foregoing if the sum
of the company's debts is greater than all of the company's property at a fair
valuation, or if the present fair saleable value of the company's assets is
less than the amount that will be required to pay its probable liability on
its existing debts as they become absolute and mature. There can be no
assurances as to what standards a court would apply to determine whether the
Company or DMC were solvent at the relevant time, or whether, whatever
standard was applied, the Notes or the Guarantee would not be voided on
another of the grounds set forth above.
 
ABSENCE OF PRIOR PUBLIC MARKET FOR NEW NOTES
 
  The New Notes will constitute a new class of securities with no established
trading market. Although the New Notes will generally be permitted to be
resold or otherwise transferred by nonaffiliates of the Company without
compliance with the registration requirements under the Securities Act, the
Company does not intend to apply for a listing of the New Notes on any
securities exchange or to arrange for the New Notes to be quoted on the NASDAQ
National Market or other quotation system. Merrill Lynch has advised the
Company that it currently intends to make a market in the New Notes; however,
Merrill Lynch is not obligated to do so, and any market-making with respect to
the New Notes may be discontinued at any time without notice. As a result,
there can be no assurance that an active trading market for the New Notes will
develop. If a market were to develop, the New Notes could trade at prices that
may be lower than the initial market values thereof depending on many factors,
including prevailing interest rates and the markets for similar securities.
 
RESTRICTIONS ON RESALE
 
  The Old Notes were offered and sold by the Company in a private offering
exempt from registration pursuant to the Securities Act and have been resold
pursuant to Rule 144A, Regulation S and certain other available exemptions
under the Securities Act. As a result, the Old Notes may not be reoffered or
resold by purchasers, except pursuant to an effective registration statement
under the Securities Act, or pursuant to an applicable exemption from such
registration.
 
  Based on interpretations by the staff of the Commission, the Company
believes that each holder (other than (i) a broker-dealer who purchased Old
Notes directly from the Company for resale pursuant to Rule 144A of the
Securities Act or any other available exemption under the Securities Act, (ii)
an "affiliate" of the Company
 
                                      18
<PAGE>
 
within the meaning of Rule 405 under the Securities Act or (iii) a broker-
dealer who acquired the Old Notes as a result of market-making or other
trading activities) who duly exchanges Old Notes for New Notes in the Exchange
Offer will receive notes that are freely transferable under the Securities
Act, provided, that such New Notes are acquired in the ordinary course of such
holder's business and that such holder is not participating, and has no
arrangement or understanding with any other person to participate, in a
distribution (within the meaning of the Securities Act) of the New Notes. The
Company has not, however, sought its own no-action letter from the staff of
the Commission regarding resales of the New Notes and there can be no
assurance that the staff of the Commission would make a similar determination
with respect to the resale of the New Notes. Any holder of Old Notes who is
not able to rely upon such staff interpretations must comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with any sale of such Old Notes, unless such sale is made pursuant
to an exemption from such requirements. See "Prospectus Summary--The Exchange
Offer."
 
CERTAIN MARKET CONSEQUENCES OF FAILURE TO EXCHANGE OLD NOTES
 
  To the extent that Old Notes are tendered and accepted for exchange pursuant
to the Exchange Offer, the trading market for Old Notes that remain
outstanding may be significantly more limited, which might adversely affect
the liquidity of the Old Notes not tendered for exchange. The extent of the
market therefor and the availability of price quotations would depend upon a
number of factors, including the number of holders of Old Notes remaining at
such time and the interest in maintaining a market in such Old Notes on the
part of securities firms. An issue of securities with a smaller outstanding
market value available for trading (the "float") may command a lower price
than would a comparable issue of securities with a greater float. As a result,
the market price for Old Notes that are not exchanged in the Exchange Offer
may be affected adversely to the extent that the amount of Old Notes exchanged
pursuant to the Exchange Offer reduces the float. The reduced float also may
make the trading price of the Old Notes that are not exchanged more volatile.
In addition, holders of Old Notes who do not exchange their Old Notes for New
Notes pursuant to the Exchange Offer will continue to be subject to
restrictions on transfer of such Old Notes contained in the legend thereon. In
general, the Old Notes may be offered or sold unless registered under the
Securities Act, except pursuant to an exemption from, or in a transaction not
subject to, the Securities Act and applicable state securities laws. The
Company does not currently anticipate that it will register the Old Notes
under the Securities Act. See "Risk Factors--Restrictions on Resale" and "The
Exchange Offer--Consequences of Failure to Exchange."

                              THE EXCHANGE OFFER
 
  The following discussion set forth or summarizes what the Company believes
are the material terms of the Exchange Offer. This Summary is qualified in its
entirety by reference to the full text of the documents underlying the
Exchange Offer, copies of which are filed as exhibits to the Registration
Statement of which this Prospectus is a part, and are incorporated by
reference herein.
 
PURPOSE AND EFFECT
 
  The Old Notes were sold by the Company to the Initial Purchasers on November
5, 1997 pursuant to the Purchase Agreement. The Initial Purchasers
subsequently resold the Old Notes in reliance on Rule 144A and Regulation S.
The Company, DMC and the Initial Purchasers also entered into the Registration
Rights Agreement, pursuant to which the Company agreed to use its best efforts
(i) to file an exchange offer registration statement ("Exchange Offer
Registration Statement") with the Commission under the Securities Act
concerning the Exchange Offer within 90 days after the Issue Date, (ii) to
cause the Exchange Offer Registration Statement to be declared effective by
the Commission within 150 days after the Issue Date, (iii) to keep the
Exchange Offer Registration Statement effective until the closing of the
Exchange Offer and (iv) to cause the Exchange Offer to be consummated 180 days
after the Issue Date. Pursuant to such Registration Rights Agreement, the
Company will endeavor to, within the applicable time periods, register under
the Securities Act all of the New Notes pursuant to a registration statement
under which the Company will offer each holder of Old Notes the opportunity to
exchange any and all of the outstanding Old Notes held by such holder for New
Notes in an aggregate principal amount equal to the aggregate principal amount
of Old Notes tendered for exchange by such holder. Subject to limited
exceptions, the Exchange Offer being made hereby, if commenced and consummated
within such applicable time periods, will satisfy those requirements under the
Registration Rights Agreement. In such event, Old Notes not exchanged for New
Notes in the Exchange Offer would remain outstanding and would continue to
accrue interest, but would generally not retain any rights under the
Registration Rights Agreement. Holders of Old Notes seeking liquidity in their
investment would have to rely on an exemption to the registration requirements
under the securities laws, including the Securities Act. This Exchange Offer
is intended to satisfy the Company's exchange offer obligations under the
Registration Rights Agreement.
 
TERMS OF THE EXCHANGE OFFER
 
  The Company hereby offers, upon the terms and subject to the conditions set
forth herein and in the accompanying Letter of Transmittal, to exchange $1,000
in principal amount of the New Notes for each $1,000 in principal amount of
the outstanding Old Notes. The Company will accept for exchange any and all
Old Notes that are validly tendered on or prior to 5:00 p.m., New York City
time, on the Expiration Date. Tenders of the Old Notes may be withdrawn in
accordance with the procedures described under "--Withdrawal Rights" at any
time prior to 5:00 p.m., New York City time, on the Expiration Date. The
Exchange Offer is not conditioned upon any minimum principal amount of Old
Notes being tendered for exchange. However, the Exchange Offer is subject to
certain customary conditions that may be waived by the Company, and to the
terms and provisions of the Registration Rights Agreement. See "--Conditions
of the Exchange Offer."
 
  Old Notes may be tendered only in multiples of $1,000. Subject to the
foregoing, holders may tender less than the aggregate principal amount
represented by the Old Notes held by them, provided that they appropriately
indicate this fact on the Letter Of Transmittal accompanying the tendered Old
Notes (or so indicate pursuant to the procedures for book-entry transfer).
 
  As of the date of this Prospectus, $100 million in aggregate principal
amount of the Old Notes is outstanding, the maximum amount authorized by the
Indenture for all Notes. This Prospectus, together with the Letter of
Transmittal, is first being sent on or about      , 1998, to all holders of
Old Notes known to the Company.
 
                                      20
<PAGE>
 
  Because the Exchange Offer is for any and all Old Notes, the number of Old
Notes tendered and exchanged in the Exchange Offer will reduce the principal
amount of Old Notes outstanding. Following the consummation of the Exchange
Offer, holders who did not tender their Old Notes generally will not have any
further registration rights under the Registration Rights Agreement, and such
Old Notes will continue to be subject to certain restrictions on transfer.
Accordingly, the liquidity of the market for such Old Notes could be adversely
affected. The Old Notes are currently eligible for sale pursuant to Rule 144A
through the Private Offering, Resales and Trading through Automated Linkages
("PORTAL") system. Because the Company anticipates that most holders of Old
Notes will elect to exchange such Old Notes for New Notes due to the absence
of restrictions on the resale of New Notes under the Securities Act, the
Company anticipates that the liquidity of the market for any Old Notes
remaining after the consummation of the Exchange Offer may be substantially
limited. See "Risk Factors--Certain Market Consequences of Failure to Exchange
Old Notes."
 
  The form and terms of the New Notes are generally the same as the form and
terms of the Old Notes, except that (i) the New Notes have been registered
under the Securities Act and will not bear legends restricting the transfer
thereof, (ii) the holders of New Notes will not be entitled to any Additional
Interest under the terms of the Registration Rights Agreement and (iii)
holders of New Notes will not be entitled to certain other rights under the
Registration Rights Agreement. The New Notes will evidence the same debt as
the Old Notes and will be entitled to the benefits of the Indenture.
 
  The Company shall be deemed to have accepted validly tendered Old Notes
when, as and if the Company has given oral or written notice thereof to the
Exchange Agent. The Exchange Agent will act as agent for the tendering holders
of Old Notes and for the purposes of receiving the New Notes from the Company
and delivering New Notes to such holders.
 
  If any tendered Old Notes are not accepted for exchange because of an
invalid tender, the occurrence of certain other events set forth herein or
otherwise, certificates for any such unaccepted Old Notes will be returned,
without expense, to the tendering holder thereof as promptly as practicable
after the Expiration Date.
 
  Holders of Old Notes do not have any appraisal or dissenters' rights in
connection with the Exchange Offer.
 
  Holders of Old Notes who tender in the Exchange Offer will not be required
to pay brokerage commissions or fees or, subject to the instructions in the
Letter of Transmittal, transfer taxes with respect to the exchange of Old
Notes pursuant to the Exchange Offer. The Company will pay all charges and
expenses, other than certain applicable taxes, in connection with the Exchange
Offer. See "--Fees and Expenses."
 
  NEITHER THE BOARD OF DIRECTORS OF THE COMPANY NOR THE COMPANY MAKES ANY
RECOMMENDATION TO HOLDERS OF OLD NOTES AS TO WHETHER TO TENDER OR REFRAIN FROM
TENDERING ALL OR ANY PORTION OF THEIR OLD NOTES PURSUANT TO THE EXCHANGE
OFFER. IN ADDITION, NO ONE HAS BEEN AUTHORIZED TO MAKE ANY SUCH
RECOMMENDATION. HOLDERS OF OLD NOTES MUST MAKE THEIR OWN DECISION WHETHER TO
TENDER PURSUANT TO THE EXCHANGE OFFER AND, IF SO, THE AGGREGATE PRINCIPAL
AMOUNT OF OLD NOTES TO TENDER, AFTER READING CAREFULLY THIS PROSPECTUS AND THE
LETTER OF TRANSMITTAL AND CONSULTING WITH THEIR ADVISORS, IF ANY, BASED ON
THEIR OWN FINANCIAL POSITION AND REQUIREMENTS.
 
EXPIRATION DATE; EXTENSIONS; AMENDMENTS
 
  The Exchange Offer shall remain open for a period of not less than 30 days
after notice is mailed to holders. The Expiration Date shall be      , 1998 at
5:00 p.m., New York City time, unless the Company, in its sole discretion,
extends the Exchange Offer, in which case the Expiration Date shall be the
latest date and time to which the Exchange Offer is extended.
 
 
                                      21
<PAGE>
 
  In order to extend the Exchange Offer, the Company will notify the Exchange
Agent of any extension by oral or written notice and will make a public
announcement thereof, by means of a press release or any other acceptable
means, each prior to 9:00 a.m., New York City time, on the next business day
after the previously scheduled Expiration Date.
 
  The Company expressly reserves the right, in its sole and absolute
discretion, (i) to delay accepting any Old Notes, (ii) to extend the Exchange
Offer, (iii) if any of the conditions set forth below under "Conditions of the
Exchange Offer" shall not have been satisfied, to terminate the Exchange
Offer, by giving oral or written notice of such delay, extension or
termination to the Exchange Agent and (iv) to waive any condition or otherwise
amend the terms of the Exchange Offer in any manner. If such waiver or
amendment constitutes a material change to the Exchange Offer, the Company
will promptly disclose such waiver or amendment by means of a prospectus
supplement that will be distributed to the registered holders of the Old
Notes, and the Company will extend the Exchange Offer to the extent required
by Rule l4e-1 under the Exchange Act.
 
  Any such delay in acceptance, extension, termination or amendment will be
followed promptly by oral or written notice thereof to the Exchange Agent and
by making a public announcement thereof, and such announcement in the case of
an extension will be made no later than 9:00 a.m., New York City time, on the
next business day after the previously scheduled Expiration Date. Without
limiting the manner in which the Company may choose to make any public
announcement and subject to applicable law, the Company shall have no
obligation to publish, advertise or otherwise communicate any such public
announcement other than by issuing a release to the Dow Jones News Service.
 
CONDITIONS OF THE EXCHANGE OFFER
 
  Notwithstanding any other provisions of the Exchange Offer, or any extension
of the Exchange Offer, the Company will not be required to accept for
exchange, or to exchange, any Old Notes for any New Notes, and, as described
below, may terminate the Exchange Offer (whether or not any Old Notes have
theretofore been accepted for exchange) or may waive any conditions to or
amend the Exchange Offer, if any of the following conditions have occurred or
exists or have not been satisfied:
 
    (i) the due tendering of Old Notes in accordance with the Exchange Offer;
 
    (ii) the Exchange Offer, or the making of any exchange by a holder,
  violates any applicable law, statute, rule, regulation or any applicable
  interpretation of the staff of the Commission;
 
    (iii) any law, statute, rule, regulation or interpretation by the staff
  of the Commission is proposed, adopted or enacted, which, in the reasonable
  judgment of the Company, might materially impair the ability of the Company
  to proceed with the Exchange Offer or materially impair the contemplated
  benefits of the Exchange Offer to the Company;
 
    (iv) each holder of Old Notes exchanged in the Exchange Offer shall have
  made certain customary representations, including representations that,
  among other things, (i) the holder is not an "affiliate" of the Company as
  defined in Rule 405 of the Securities Act, (ii) the holder is not a broker-
  dealer that acquired Old Notes directly from the Company in order to resell
  them pursuant to Rule 144A of the Securities Act or any other available
  exemption under the Securities Act, (iii) the holder will acquire the New
  Notes in the ordinary course of business and (iv) that the holder is not
  participating, and does not intend to participate, and has no arrangement
  or understanding with any person to participate, in the distribution of the
  New Notes;
 
    (v) all governmental approvals have been obtained, which such approval
  the Company shall, in its reasonable judgment, deem necessary for the
  consummation of the Exchange Offer as contemplated hereby;
 
    (vi) there shall be threatened, instituted or pending any action or
  proceeding before, or any injunction, order or decree shall have been
  issued by, any court or governmental agency or other governmental
  regulatory or administrative agency or commission, (a) seeking to restrain
  or prohibit the making or consummation of the Exchange Offer or any other
  transaction contemplated by the Exchange Offer, or
 
                                      22
<PAGE>
 
  assessing or seeking any damages as a result thereof or (b) resulting in a
  material delay in the ability of the Company to accept for exchange or
  exchange some or all of the Old Notes pursuant to the Exchange Offer;
 
    (vii) there shall have occurred (a) any general suspension of or general
  limitation on prices for, or trading in, securities on any national
  securities exchange or in the over-the-counter market, (b) any limitation
  by any governmental agency or authority which may adversely affect the
  ability of the Company to complete the transactions contemplated by the
  Exchange Offer, (c) a declaration of a banking moratorium or any suspension
  of payments in respect of banks in the United States or any limitation by
  any governmental agency or authority which adversely affects the extension
  of credit or (d) a commencement of a war, armed hostilities or other
  similar international calamity directly or indirectly involving the United
  States, or, in the case of any of the foregoing existing at the time of the
  commencement of the Exchange Offer, a material acceleration or worsening
  thereof; or
 
    (viii) any change (or any development involving a prospective change)
  shall have occurred or be threatened in the business, properties, assets,
  liabilities, financial condition, operations, results of operations or
  prospects of the Company and its subsidiaries taken as a whole that, in the
  sole judgment of the Company, is or may be adverse to the Company, or the
  Company shall have become aware of facts that, in the sole judgment of the
  Company, have or may have an adverse effect on the value of the Old Notes
  or the New Notes.
 
  If the Company determines in its sole and absolute discretion that any of
the foregoing events or conditions has occurred or exists or has not been
satisfied, the Company may, subject to applicable law, (i) terminate the
Exchange Offer (whether or not any Old Notes have theretofore been accepted
for exchange), (ii) extend the Exchange Offer and retain all Old Notes
tendered prior to the expiration of the Exchange Offer subject, however, to
the rights of holders to withdraw such Old Notes or (iii) waive any such
condition or otherwise amend the terms of the Exchange Offer in any respect.
If such waiver or amendment constitutes a material change to the Exchange
Offer, the Company will promptly disclose such waiver or amendment by means of
a prospectus supplement that will be distributed to the registered holders of
the Old Notes, and the Company will extend the Exchange Offer to the extent
required by Rule l4e-1 under the Exchange Act.
 
  The foregoing conditions are for the sole benefit of the Company and may be
waived by the Company in whole or in part at any time and from time to time in
its sole discretion. The failure by the Company at any time to exercise any of
the foregoing rights shall not be deemed a waiver of such rights and each such
right shall be deemed an ongoing right which may be asserted at any time and
from time to time. Any determination by the Company concerning the events
described above will be final and binding upon all parties.
 
  In addition, the Company will not accept for exchange any Old Notes
tendered, and no New Notes will be issued in exchange for any such Old Notes,
if at such time any stop order shall be threatened or in effect with respect
to the Registration Statement of which this Prospectus constitutes a part or
the qualification of the Indenture under the Trust Indenture Act of 1939.
 
TERMINATION OF CERTAIN RIGHTS
 
  Holders of New Notes will not be and, upon consummation of the Exchange
Offer, holders of Old Notes who were permitted to participate in the Exchange
Offer will no longer be, entitled to (i) the right to receive Additional
Interest under the Registration Rights Agreement or (ii) certain other rights
under the Registration Rights Agreement intended for the holders of
unregistered securities; provided, that holders of Old Notes who are not
permitted to participate in the Exchange Offer or who do not receive fully
tradeable New Notes pursuant to the Exchange Offer, shall have the right to
require the Company to file a Shelf Registration Statement solely for the
benefit of such holders of Old Notes and will be entitled to receive
Additional Interest following the occurrence of a Registration Default in
connection with the filing of such Shelf Registration Statement. See
"Registration Rights." Notwithstanding anything to the contrary in the
foregoing, Old Notes not tendered in the Exchange Offer will remain
outstanding and continue to accrue interest in accordance with their terms.
 
 
                                      23
<PAGE>
 
ACCRUED INTEREST ON THE OLD NOTES
 
  Holders whose Old Notes are accepted for exchange will have the right to
receive interest accrued thereon from the date of their original issuance or
the last interest payment date, as applicable, to, but not including, the date
of issuance of the New Notes, such interest to be payable with the first
interest payment on the New Notes. Interest on the Old Notes accepted for
exchange, which interest accrued at the rate of 10 1/4% per annum, will cease
to accrue on the day prior to the issuance of the New Notes.
 
PROCEDURES FOR TENDERING OLD NOTES
 
  The tender of a holder's Old Notes as set forth below and the acceptance
thereof by the Company will constitute a binding agreement between the
tendering holder and the Company upon the terms and subject to the conditions
set forth in this Prospectus and in the accompanying Letter of Transmittal.
Except as set forth below, a holder who wishes to tender Old Notes for
exchange pursuant to the Exchange Offer must transmit a properly completed and
duly executed Letter of Transmittal, including all other documents required by
such Letter of Transmittal, to the Exchange Agent at the address set forth
under "--The Exchange Agent; Assistance" prior to 5:00 p.m., New York City
time on the Expiration Date. In addition, either (i) certificates of such Old
Notes must be received by the Exchange Agent along with the Letter of
Transmittal, (ii) a timely confirmation of book-entry transfer of such Old
Notes, if such procedure is available, into the Exchange Agent's account at
DTC pursuant to the procedure for book-entry transfer described below, must be
received by the Exchange Agent prior to the Expiration Date, or (iii) the
holder must comply with the guaranteed delivery procedures described below.
 
  THE METHOD OF DELIVERY OF OLD NOTES, LETTERS OF TRANSMITTAL AND ALL OTHER
REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND RISK OF THE
ELIGIBLE HOLDER. IF SUCH DELIVERY IS BY MAIL, IT IS RECOMMENDED THAT
REGISTERED MAIL, PROPERLY INSURED, WITH RETURN RECEIPT REQUESTED, BE USED.
INSTEAD OF DELIVERY BY MAIL, IT IS RECOMMENDED THAT THE ELIGIBLE HOLDER USE AN
OVERNIGHT OR HAND DELIVERY SERVICE. IN ALL CASES, SUFFICIENT TIME SHOULD BE
ALLOWED TO ASSURE TIMELY DELIVERY. NO LETTER OF TRANSMITTAL OR OLD NOTES
SHOULD BE SENT TO THE COMPANY OR DTC. HOLDERS MAY REQUEST THEIR RESPECTIVE
BROKERS, DEALERS, COMMERCIAL BANKS, TRUST COMPANIES OR NOMINEES TO EFFECT SUCH
TENDER FOR SUCH HOLDER.
 
  Any Beneficial Owner whose Old Notes are registered in the name of a
nominee, such as a broker, dealer, commercial bank or trust company, and who
wishes to tender Old Notes in the Exchange Offer should contact such
registered holder promptly and instruct such registered holder to tender on
such Beneficial Owner's behalf. If such Beneficial Owner wishes to tender
directly, such Beneficial Owner must, prior to completing and executing the
Letter of Transmittal and tendering Old Notes, either make appropriate
arrangements to register ownership of the Old Notes in such Beneficial Owner's
name or obtain a properly completed bond power from the registered holder.
Beneficial Owners should be aware that the transfer of registered ownership
may take considerable time.
 
  The Exchange Agent will make a request to establish an account with respect
to the Old Notes at DTC for the purposes of the Exchange Offer within two
business days after the date of this Prospectus. Any financial institution
that is a participant in DTC's Book-Entry Transfer Facility system may make
book-entry delivery of the Old Notes by causing DTC to transfer such Old Notes
into the Exchange Agent's account in accordance with DTC's procedures for such
transfer. However, although delivery of the Old Notes may be effected through
book-entry transfer into the Exchange Agent's account at DTC, the Letter of
Transmittal (or facsimile thereof), properly completed and duly executed, with
any required signature guarantees and any other required documents, must in
any case, be delivered to and received by the Exchange Agent at its address
set forth under "--The Exchange Agent; Assistance" on or prior to the
Expiration Date, or the guaranteed delivery procedure set forth
 
                                      24
<PAGE>
 
below must be complied with, within the time period provided under such
procedures. Delivery of documents to DTC does not constitute delivery to the
Exchange Agent.
 
  Each signature on a Letter of Transmittal or a notice of withdrawal, as the
case may be, must be guaranteed by an Eligible Institution (as defined herein)
unless the Old Notes surrendered for exchange pursuant hereto are tendered (i)
by a registered holder of the Old Notes who has not completed either the box
entitled "Special Exchange Instructions" or the box entitled "Special Delivery
Instructions" in the Letter of Transmittal or (ii) for the account of an
Eligible Institution. In the event that a signature on a Letter of Transmittal
or a notice of withdrawal, as the case may be, is required to be guaranteed,
such signature must be guaranteed by an Eligible Institution. If the Letter of
Transmittal is signed by a person other than the registered holder of the Old
Notes, the Old Notes surrendered for exchange must be endorsed or accompanied
by appropriate bond powers and a proxy which authorizes such person to tender
the Old Notes on behalf of the registered holder, in each case, signed by the
registered holder, with the signature thereon guaranteed by an Eligible
Institution. The term "registered holder" as used herein with respect to the
Old Notes means any person in whose name the Old Notes are registered on the
books of the Registrar. The term "Eligible Institution" as used herein means a
firm which is a member of a registered national securities exchange or of the
National Association of Securities Dealers, Inc., a commercial bank or trust
company having an office or correspondent in the United States or any other
"eligible guarantor institution" as such term is defined in Rule 17Ad-15 under
the Exchange Act.
 
  All questions as to the validity, form, eligibility (including time of
receipt), acceptance and withdrawal of Old Notes tendered for exchange will be
determined by the Company in its sole discretion, which determination shall be
final and binding. The Company reserves the absolute right to reject any and
all Old Notes not properly tendered and to reject any Old Notes the Company's
acceptance of which might, in the judgment of the Company or its counsel, be
unlawful. The Company also reserves the absolute right to waive any defects or
irregularities or conditions of the Exchange Offer as to particular Old Notes
either before or after the Expiration Date (including the right to waive the
ineligibility of any holder who seeks to tender Old Notes in the Exchange
Offer). The interpretation of the terms and conditions of the Exchange Offer
(including the Letter of Transmittal and the instructions thereto) by the
Company shall be final and binding on all parties. Unless waived, any defects
or irregularities in connection with tenders of Old Notes for exchange must be
cured within such period of time as the Company shall determine. Neither the
Company, the Exchange Agent nor any other person shall be under any duty to
give notification of defects or irregularities with respect to tenders of Old
Notes, nor shall any of them incur any liability for failure to give
notification of defects or irregularities with respect to tenders of Old
Notes. Tenders of the Old Notes will not be deemed to have been made until
such irregularities have been cured or waived.
 
  If any Letter of Transmittal, endorsement, bond power, power of attorney or
any other document required by the Letter of Transmittal is signed by a
trustee, executor, administrator, guardian, attorney-in-fact, officer of a
corporation or other person acting in a fiduciary or representative capacity,
such person should so indicate when signing, and, unless waived by the
Company, proper evidence satisfactory to the Company, in its sole discretion,
of such person's authority so to act must be submitted with the Letter of
Transmittal.
 
  By tendering, each registered holder will represent to the Company, among
other things, that: (i) the holder is not an "affiliate" of the Company as
defined in Rule 405 of the Securities Act, (ii) the holder is not a broker-
dealer that acquired Old Notes directly from the Company in order to resell
them pursuant to Rule 144A of the Securities Act or any other available
exemption under the Securities Act, (iii) the holder will acquire the New
Notes in the ordinary course of business and (iv) the holder is not
participating, and does not intend to participate, and has no arrangement or
understanding with any person to participate, in the distribution of the New
Notes. Any holder of Old Notes that is unable to make these representations to
the Company will not be able to rely on the interpretations of the staff of
the Commission described in "--Resales of New Notes" and therefore will be
required to comply with the registration and prospectus delivery requirements
of the Securities Act in connection with any sale of such Old Notes, unless
such sale is made pursuant to an exemption from such requirements.
 
                                      25

GUARANTEED DELIVERY PROCEDURES
 
  Holders who wish to tender their Old Notes and (i) whose Old Notes are not
immediately available or (ii) who cannot deliver their Old Notes, the Letter
of Transmittal or any other documents required by the Letter of Transmittal to
the Exchange Agent on or prior to the Expiration Date or (iii) who cannot
complete the procedure for book-entry transfer on a timely basis, may tender
their Old Notes according to the guaranteed delivery procedures set forth in
the Letter of Transmittal. Pursuant to such procedures: (i) such tender must
be made by or through an Eligible Institution, (ii) prior to the Expiration
Date, the Exchange Agent must have received from the holder and the Eligible
Institution a properly completed and duly executed Notice of Guaranteed
Delivery (by facsimile transmission, mail or hand delivery) setting forth the
name and address of the holder, the certificate or registration number or
numbers of the tendered Old Notes, and the principal amount of tendered Old
Notes, stating that the tender is being made thereby and guaranteeing that, at
least within four (4) New York Stock Exchange trading days after the
Expiration Date, the tendered Old Notes, a duly executed Letter of Transmittal
(or a facsimile thereof) and any other required documents will be deposited by
the Eligible Institution with the Exchange Agent and (iii) such properly
completed and executed documents required by the Letter of Transmittal (or a
facsimile thereof) and the tendered Old Notes in proper form for transfer (or
confirmation of a book-entry transfer of such Old Notes into the Exchange
Agent's account at DTC) must be received by the Exchange Agent within at least
four (4) New York Stock Exchange trading days after the Expiration Date.
 
ACCEPTANCE OF OLD NOTES FOR EXCHANGE; DELIVERY OF NEW NOTES
 
  Upon satisfaction or waiver of all the conditions to the Exchange Offer, the
Company will accept any and all Old Notes that are properly tendered in the
Exchange Offer prior to 5:00 p.m., New York City time, on the Expiration Date.
The New Notes issued pursuant to the Exchange Offer will be delivered as
promptly as practicable after acceptance of the Old Notes. For purposes of the
Exchange Offer, the Company shall be deemed to have accepted validly tendered
Old Notes, when, as, and if the Company has given oral or written notice
thereof to the Exchange Agent.
 
  In all cases, issuances of New Notes for Old Notes that are accepted for
exchange pursuant to the Exchange Offer will be made only after timely receipt
by the Exchange Agent of such Old Notes, a properly completed and duly
executed Letter of Transmittal (or a facsimile thereof) and all other required
documents (or of confirmation of a book-entry transfer of such Old Notes into
the Exchange Agent's account at DTC); provided, that the Company reserves the
absolute right to waive any defects or irregularities in the tender or
conditions of the Exchange Offer. If any tendered Old Notes are not accepted
for any reason, such unaccepted Old Notes will be returned without expense to
the tendering holder thereof as promptly as practicable after the expiration
or termination of the Exchange Offer.
 
WITHDRAWAL RIGHTS
 
  Tenders of the Old Notes may be withdrawn by delivery of a written or
facsimile transmission notice to the Exchange Agent, at its address set forth
herein, at any time prior to 5:00 p.m., New York City time, on the Expiration
Date after which tenders of Old Notes are irrevocable. Any such notice of
withdrawal must (i) specify the name of the person having deposited the Old
Notes to be withdrawn (the "Depositor"), (ii) identify the Old Notes to be
withdrawn (including the certificate or registration number or numbers and
principal amount of such Old Notes, as applicable or, in the case of notes
transferred by book-entry transfer, the name and number of the account at DTC
to be credited), (iii) be signed by the Depositor in the same manner as the
original signature on the Letter of Transmittal by which such Old Notes were
tendered (including any required signature guarantees) or be accompanied by a
bond power in the name of the person withdrawing the tender, in satisfactory
form as determined by the Company in its sole discretion, duly executed by the
registered holder, with the signature thereon guaranteed by an Eligible
Institution together with the other documents required upon transfer by the
Indenture, (iv) specify the name in which such Old Notes are to be re-
registered, if different from the Depositor,
 
                                      26
<PAGE>
 
pursuant to such documents of transfer and (v) include a statement that such
holder is withdrawing its election to have such Old Notes exchanged. All
questions as to the validity, form and eligibility (including time of receipt)
of such notices will be determined by the Company, in its sole discretion. The
Old Notes so withdrawn will be deemed not to have been validly tendered for
exchange for purposes of the Exchange Offer and no New Notes will be issued
with respect thereto unless the Old Notes so withdrawn are validly retendered.
Any Old Notes which have been tendered for exchange but which are withdrawn
will be returned to the holder thereof without cost to such holder as promptly
as practicable after withdrawal. Properly withdrawn Old Notes may be
retendered by following one of the procedures described under "--Procedures
for Tendering Old Notes" at any time on or prior to the Expiration Date.
 
THE EXCHANGE AGENT; ASSISTANCE
 
  LaSalle National Bank has been appointed the Exchange Agent for the Exchange
Offer. All tendered Old Notes, executed Letters of Transmittal and other
related documents should be directed to the Exchange Agent. Questions and
requests for assistance and requests for additional copies of the Prospectus,
the Letter of Transmittal and other related documents should be addressed to
the Exchange Agent as follows:

                                   904-2936
 
  DELIVERY OF DOCUMENTS TO AN ADDRESS OTHER THAN AS SET FORTH ABOVE OR
TRANSMISSION OF DOCUMENTS VIA FACSIMILE OTHER THAN AS SET FORTH ABOVE DOES NOT
CONSTITUTE A VALID DELIVERY OF SUCH DOCUMENTS.
 
FEES AND EXPENSES
 
  The expenses of soliciting tenders pursuant to the Exchange Offer will be
borne by the Company. The principal solicitation for tenders pursuant to the
Exchange Offer is being made by mail. However, additional solicitations may be
made by facsimile, telephone or in person by officers and regular employees of
the Company and its affiliates.
 
  The Company has not retained any dealer-manager in connection with the
Exchange Offer and will not make any payments to brokers, dealers or others
soliciting acceptance of the Exchange Offer. The Company, however, will pay
the Exchange Agent reasonable and customary fees for its services and will
reimburse it for its reasonable out-of-pocket expenses in connection therewith
and pay other registration expenses, including fees and expenses of the
Trustee, filing fees, blue sky fees and printing and distribution expenses.
 
  The Company will pay all transfer taxes, if any, applicable to the exchange
of Old Notes pursuant to the Exchange Offer. If, however, certificates
representing New Notes or Old Notes for principal amounts not tendered or
accepted for exchange are to be delivered to, or are to be issued in the name
of, any person other than the registered holder of the Old Notes tendered or
if a transfer tax is imposed for any reason other than the exchange of Old
Notes pursuant to the Exchange Offer, then the amount of any such transfer
taxes (whether imposed on the registered holder or any other persons) will be
payable by the tendering holder. If satisfactory evidence of payment of such
taxes or exemption is not submitted with the Letter of Transmittal, the amount
of such transfer taxes will be billed directly to such tendering holder.
 
                                      27
<PAGE>
 
ACCOUNTING TREATMENT
 
  The New Notes will be recorded at the same carrying value as the Old Notes,
as reflected in the Company's accounting records on the date of the exchange.
Accordingly, no gain or loss will be recognized by the Company for accounting
purposes in connection with the Exchange Offer. The expenses of the Exchange
Offer will be amortized over the term of the New Notes.
 
RESALES OF NEW NOTES
 
  Upon consummation of the Exchange Offer, holders of Old Notes who were not
prohibited from participating in the Exchange Offer and did not tender their
Old Notes will generally not have any registration rights under the
Registration Rights Agreement with respect to such nontendered Old Notes and
such Old Notes will continue to be subject to the restrictions on transfer
contained in the legend thereon. In general, the Old Notes may not be offered
or sold unless registered under the Securities Act and applicable state
securities laws, except pursuant to an exemption from, or in a transaction not
subject to, the Securities Act and applicable state securities laws. The
Company does not currently anticipate that it will register the Old Notes
under the Securities Act.
 
  The Company is making the Exchange Offer in reliance on the position of the
staff of the Commission as set forth in certain interpretive letters addressed
to third parties in other transactions. However, the Company has not sought
its own interpretive letter and there can be no assurance that the staff of
the Commission would make a similar determination with respect to the Exchange
Offer as it has in such interpretive letters to third parties. Based on these
interpretations by the staff of the Commission, the Company believes that New
Notes issued pursuant to the Exchange Offer in exchange for Old Notes may be
offered for resale, resold and otherwise transferred by a holder (other than
(i) a broker-dealer who purchased Old Notes directly from the Company for
resale pursuant to Rule 144A or any other available exemption under the
Securities Act, (ii) an "affiliate" of the Company within the meaning of Rule
405 under the Securities Act or (iii) a broker-dealer who acquired the Old
Securities as a result of market-making or other trading activities), without
further compliance with the registration and prospectus delivery provisions of
the Securities Act, provided, that such holder is acquiring the New Notes in
the ordinary course of business and is not participating, and has no
arrangement or understanding with any person to participate, in the
distribution of the New Notes. Any holder wishing to accept the Exchange Offer
must represent to the Company, as required by the Registration Rights
Agreement, that (i) it is not an "affiliate" of the Company as defined in Rule
405 of the Securities Act, (ii) it is not a broker-dealer that acquired Old
Notes directly from the Company in order to resell them pursuant to Rule 144A
of the Securities Act or any other available exemption under the Securities
Act, (iii) it will acquire the New Notes in the ordinary course of business
and (iv) it is not participating, and does not intend to participate, and has
no arrangement or understanding with any person to participate, in the
distribution of the New Notes. Any holder of Old Notes that is unable to make
these representations to the Company will not be able to rely on the
interpretations of the staff of the Commission described above and therefore
will be required to comply with the registration and prospectus delivery
requirements of the Securities Act in connection with any sale of such Old
Notes unless such sale is made pursuant to an exemption from such
requirements.
 
  Each broker-dealer who receives New Notes for its own account pursuant to
the Exchange Offer must acknowledge that it acquired the Old Notes for its own
account as a result of market-making activities or other trading activities
and, because it may be deemed a statutory underwriter, must agree that it will
deliver a prospectus meeting the requirements of the Securities Act in
connection with any resale of such New Notes. The Letter of Transmittal states
that by so acknowledging and by delivering a prospectus, a broker-dealer will
not be deemed to admit that it is an "underwriter" within the meaning of the
Securities Act. Based on the position taken by the staff of the Commission in
the interpretive letters referred to above, the Company believes that
Participating Broker-Dealers may fulfill their prospectus delivery
requirements with respect to the New Notes received upon exchange of such Old
Notes (other than Old Notes that represent an unsold allotment from the
 
                                      28
<PAGE>
 
original sale of the Old Notes) with a prospectus meeting the requirements of
the Securities Act, which may be the prospectus prepared for an exchange offer
so long as it contains a description of the plan of distribution with respect
to the resale of such New Notes. Accordingly, this Prospectus may be used by a
Participating Broker-Dealer during the period referred to below in connection
with resales of New Notes received in exchange for Old Notes where such Old
Notes were acquired by such Participating Broker-Dealer for its own account as
a result of market-making or other trading activities. Subject to certain
provisions and time limitations set forth in the Registration Rights
Agreement, the Company has agreed that this Prospectus may be used by a
Participating Broker-Dealer in connection with resales of such New Notes. See
"Plan of Distribution." However, a Participating Broker-Dealer who intends to
use this Prospectus in connection with the resale of New Notes received in
exchange for Old Notes pursuant to the Exchange Offer must notify the Company,
or cause the Company to be notified, on or prior to the Expiration Date, that
it is a Participating Broker-Dealer. Such notice may be given in the space
provided for that purpose in the Letter of Transmittal or may be delivered to
the Exchange Agent at one of the addresses set forth herein under "--The
Exchange Agent; Assistance." A Participating Broker-Dealer who delivers this
Prospectus to purchasers in connection with resales of New Notes will be
subject to certain of the civil liabilities under the Securities Act and will
be bound by the provisions of the Registration Rights Agreement (including
certain indemnification rights and obligations). Any Participating Broker-
Dealer who is an "affiliate" of the Company may not rely on such interpretive
letters and must comply with the registration and prospectus delivery
requirements of the Securities Act in connection with any resale transaction.
 
  In that regard, each Participating Broker-Dealer who surrenders Old Notes
pursuant to The Exchange Offer will be deemed to have agreed, by execution of
the Letter of Transmittal, that, upon receipt of notice from the Company of
the occurrence of any event or the discovery of any fact which makes any
statement contained in this Prospectus untrue in any material respect or which
causes this Prospectus to omit to state a material fact necessary in order to
make the statements contained herein, in light of the circumstances under
which they were made, not misleading or of the occurrence of certain other
events specified in the Registration Rights Agreement, such Participating
Broker-Dealer will suspend the sale of New Notes pursuant to this Prospectus
until the Company has amended or supplemented this Prospectus to correct such
misstatement or omission and has furnished copies of the amended or
supplemented Prospectus to such Participating Broker-Dealer or the Company has
given notice that the sale of the New Notes may be resumed, as the case may
be.
 
CONSEQUENCES OF FAILURE TO EXCHANGE
 
  Holders of Old Notes who are permitted to participate in the Exchange Offer
and who do not tender their Old Notes generally will not have any further
registration rights under the Registration Rights Agreement or otherwise.
Accordingly, any holder that does not exchange such holder's Old Notes for New
Notes will continue to hold the untendered Old Notes and will be entitled to
all the rights and limitations applicable thereto under the Indenture, except
to the extent that such rights or limitations, by their terms, terminate or
cease to have further effectiveness as a result of the Exchange Offer.
 
  The Old Notes that are not exchanged for New Notes pursuant to the Exchange
Offer will continue to be subject to the restrictions on transfer contained in
the legend thereon. In general, the Old Note may not be offered or sold,
unless registered under the Securities Act, except pursuant to an exemption
from, or in a transaction not subject to, the Securities Act and applicable
state securities laws. The Company does not currently anticipate that it will
register the Old Notes under the Securities Act. Accordingly, such Old Notes
may be resold only (i) to the Company (upon redemption thereof or otherwise),

States to a foreign person pursuant to the exemption from the registration
requirements of the Securities Act provided by Regulation S, (v) to an

no present plans to acquire any Old Notes that are not tendered in the

                                USE OF PROCEEDS
 
  There will be no proceeds to the Company from the exchange of the Old Notes
for New Notes pursuant to the Exchange Offer.
 
  The net proceeds to the Company from the Offering were approximately $96.1
million, after deducting the Initial Purchasers' discount and other expenses
related to the Offering. The Company used the net proceeds of the Offering as
follows: (i) approximately $58.0 million to repay certain notes and other
indebtedness described below; (ii) approximately $19.3 million to consummate
the DMC Acquisition, (iii) $7.0 million to pay a dividend to holders of the
Company's capital stock, (iv) approximately $1.5 million to purchase an
84,000-square-foot facility for the assembly of the Company's products in Mt.
Olive, North Carolina, and (v) approximately $10.3 million for general
corporate purposes. Prior to the application of the net proceeds from the
Offering as described above, such funds were invested in short-term,
investment grade securities.
 
  The notes and other indebtedness that were repaid with a portion of the net
proceeds to the Company from the Offering consisted of the following: (i)
$35.8 million outstanding as of September 30, 1997 under the credit agreement,
dated as of April 26, 1995, as amended (the "Bank Credit Facility"), between
the Company and LaSalle National Bank (the "Bank"), including $32.8 million
under the revolver, which bore interest at a variable rate based on the prime
rate or LIBOR (7.6% at September 30, 1997), and was scheduled to mature on May
31, 1999, and $3.0 million under a term note, which bore interest at a
variable rate based on the prime rate (8.8% at September 30, 1997) and was
scheduled to mature on June 1, 2001; (ii) $17.1 million principal amount of
Stockholder Notes (as defined herein) outstanding as of September 30, 1997,
which were repurchased at a discount for approximately $15.2 million, and
which bore interest at 8% and were scheduled to mature on either May 1, 2002
or May 1, 2006 (see "Certain Relationships and Related Transactions--
Management Buyout--Redemption Agreements"); (iii) $3.5 million outstanding as
of September 30, 1997 under a note payable to The CIT Group/Equipment
Financing, Inc., which bore interest at 9% and was scheduled to mature on
April 30, 2000; (iv) $2.6 million outstanding under a note payable to
Metropolitan Life Insurance Company, which bore interest at 8.45% and was
scheduled to mature on July 1, 2006; (v) $0.8 million outstanding as of
September 30, 1997 under a note payable to American National Bank, which bore
interest at 82% of the bank's prime rate and was scheduled to mature on
November 1, 2007; and (vi) $0.1 million outstanding under a capital lease on
equipment, which bore interest at 8% and was scheduled to mature on March 1,
1998. Such notes and other indebtedness constituted approximately 95% of the
Company's indebtedness prior to the Offering. See Note 7 to Consolidated
Financial Statements.

(1) In December 1995, the Company signed an agreement to sell the working
    capital and fixed assets of its Heritage Vinyl Division. In January 1996,
    the sale was closed. The Company's 1994 and prior year financial
    statements were restated to reflect this discontinued operation. See Note
    3 to Consolidated Financial Statements.
(2) The write-off of the affiliate receivable resulted from a significant
    customer, who is an affiliate of the Company, ceasing distribution
    operations and selling its only division in December 1995. The write-off
    of the affiliate receivable represents the portion of the remaining
    receivable due that was not collectible. See Note 11 to Consolidated
    Financial Statements.
 
                                      33

(3) The ratio of earnings to fixed charges is expressed as the ratio of fixed
    charges plus pretax earnings to fixed charges. Fixed charges include
    interest on borrowings, amortization of deferred financing costs and the
    interest portion of rent expense. Earnings were insufficient to cover
    fixed charges for the year ended December 31, 1995 by $1.8 million.
(4) EBITDA represents income from continuing operations (excluding the write-
    off of an affiliate receivable) plus interest expense (including
    amortization of debt issuance costs), depreciation and amortization.
    EBITDA is presented here to provide additional information about the
    Company's ability to meet its future debt service, capital expenditure and
    working capital requirements. EBITDA is not a measure of financial
    performance under GAAP and should not be considered as an alternative
    either to net income as an indicator of the Company's operating
    performance, or to cash flows as a measure of the Company's liquidity.
(5) Total stockholders' deficit at December 31, 1996 resulted from a
    management buyout of the Company's capital stock in June 1996. The Company
    purchased its capital stock from selling shareholders using cash and
    notes. In order to fund a portion of the cash payments made by the
    Company, the Company obtained a $4.0 million term loan. See "Certain
    Relationships and Related Transactions--Management Buyout" and Note 6 to
    Consolidated Financial Statements.

                           PRO FORMA FINANCIAL DATA
 
  The following unaudited pro forma condensed combined balance sheet of the
Company gives effect to the Offering, the application of the net proceeds
therefrom and the DMC Acquisition as if such transactions had occurred on
September 30, 1997. The following unaudited pro forma combined statements of
income of the Company give effect to the Offering, the application of the net
proceeds therefrom and the DMC Acquisition as if such transactions had
occurred on the first day of the periods presented. The DMC Acquisition was
consummated on November 5, 1997. See "Business--DMC Acquisition."
 
  For purposes of the accompanying pro forma combined financial statements,
acquisition-related adjustments, all made pursuant to the purchase method of
accounting, and other adjustments, have been reflected on an estimated basis
using the most recent information available. No assurances can be given that
the final determinations of the fair value of assets acquired and liabilities
assumed by the Company in the DMC Acquisition will not differ from the
adjustments presented herein. Such determinations will be made within one year
of the DMC Acquisition and are not expected to be materially different from
the estimates used herein.
 
  The unaudited pro forma combined financial statements should be read in
conjunction with the separate historical financial statements and related
notes thereto of the Company and DMC included elsewhere in this Offering
Memorandum. The pro forma combined financial statements do not purport to be
indicative of the results that actually would have been obtained had all the
transactions been completed as of the assumed dates and for the periods
presented and are not intended to be a projection of future results or trends.
Operating results for any interim period are not necessarily indicative of
results that may be expected for the full year.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
  The following discussion of the financial condition and results of
operations of the Company should be read in conjunction with the Consolidated
Financial Statements and the notes thereto appearing elsewhere in this
Prospectus.
 
GENERAL
 
  The Company is a leading manufacturer and supplier of agricultural equipment
and services worldwide. The Company's grain, swine and poultry products are
used by producers and purchasers of grain, and by producers of swine and
poultry. Fluctuations in grain and feed prices directly impact sales of the
Company's grain equipment. Because the primary cost of producing swine and
poultry is the cost of the feed grain consumed by animals, fluctuations in the
supply and cost of grain to users of the Company's products also can impact
sales of the Company's swine and poultry equipment. The Company believes,
however, that its diversified product offerings mitigate some of the effects
of fluctuations in the price of grain since the demand for grain storage,
drying and handling equipment tends to increase during periods of higher grain
prices, which somewhat offsets the reduction in demand during such periods for
the Company's products by producers of swine and poultry. See "Business--
Industry Overview."
 
  Sales of agricultural equipment are seasonal, with farmers traditionally
purchasing grain storage bins and grain drying and handling equipment in the
summer and fall in conjunction with the harvesting season, and swine and
poultry producers purchasing equipment during prime construction periods in
the spring, summer and fall. The Company's net sales and net income have
historically been lower during the first and fourth fiscal quarters as
compared to the second and third quarters. See "Risk Factors--Agricultural
Industry; Seasonality."
 
  Although the Company's sales are primarily denominated in U.S. dollars and
are not affected by currency fluctuations, the production costs, profit
margins and competitive position of the Company are affected by the strength
of the U.S. dollar relative to the strength of the currencies in countries
where its products are sold. With respect to sales that are not denominated in
U.S. dollars, the Company seeks to hedge against currency fluctuations on a
limited basis. In 1996, the Company's foreign sales accounted for 31% of net
sales. See "Risk Factors--International Operations; Exposure to Foreign
Currency Risk."
 
  The primary raw materials used by the Company to manufacture its products
are steel and polymers. Fluctuations in the prices of steel and, to a lesser
extent, polymer materials can impact the Company's cost of sales. From 1994
through 1996, the price of steel and polymers remained relatively constant.
The Company has experienced modest price decreases in steel and polymers
during 1997. See "Risk Factors--Raw Materials Price Volatility."
 
  The Company's current business was founded in 1972 as a subsidiary of the
Sloan Implement Company, Inc. ("Sloan Implement"), a distributor of John Deere
farm equipment owned by the Sloan family. This subsidiary was later merged
into Sloan Implement and became its manufacturing division and Sloan Implement
changed its name to Grain Systems, Inc. ("Grain Systems"). In 1994, the farm
equipment distributor division of Grain Systems was spun off as a newly-formed
corporation with the manufacturing division surviving as Grain Systems. The
Company's 1994 and prior year financial statements were restated to exclude
the results of operations and financial position of the farm equipment
distributor division. In 1995, Grain Systems changed its name to The GSI
Group, Inc. and in 1996, all of the capital stock of the Company was acquired
by Craig Sloan and certain other executives of the Company. See "Certain
Relationships and Related Transactions--Management Buyout." The Company
currently operates as a Subchapter "S" corporation and, accordingly, is not
subject to federal income taxation for the periods for which financial
information has been presented herein. Because the Company's stockholders are
subject to tax liabilities based on their pro rata shares of the Company's
income, it is the Company's policy to make periodic distributions to its
stockholders in amounts equal to such tax liabilities. See "Certain
Relationships and Related Transactions--Other Related Party Transactions."

RESULTS OF OPERATIONS
 
Nine Months Ended September 30, 1997 Compared to Nine Months Ended September
30, 1996
 
  Net sales increased 25.1% or $34.5 million to $172.0 million in the nine
months ended September 30, 1997 compared to $137.5 million in the
corresponding period of 1996. This increase was primarily a result of
increased sales of grain storage products resulting primarily from
historically high domestic grain prices in 1996, increased sales of swine
equipment resulting primarily from continuing strong construction demand for
larger swine facilities, and increased international sales of swine, poultry
and grain storage equipment resulting primarily from regional market
penetration and successful bids on turn-key grain storage projects.
 
  Gross profit increased to $42.0 million in the nine months ended September
30, 1997 or 24.4% of net sales compared to $33.0 million or 24.0% of net sales
in the corresponding period of 1996. This increase reflected the impact of
increased sales, as well as the benefit of price increases in certain product
lines. These positive impacts were offset by a change in sales mix towards
lower margin products within the swine product line.
 
  Selling, general and administrative expenses increased 18.9% or $4.0 million
to $25.5 million in the nine months ended September 30, 1997 from $21.4
million in the corresponding period of 1996. As a percentage of net sales,
however, selling, general and administrative expenses decreased to 14.8% in
the nine months ended September 30, 1997 compared to 15.6% in the
corresponding period in 1996. This decrease reflected the Company's ability to
increase sales volume without a corresponding increase in the number of
selling and administrative personnel despite an increase in the bad debt
reserve of $1.1 million.
 
  Operating income increased 42.9% or $5.0 million to $16.5 million in the
nine months ended September 30, 1997 compared to $11.6 million in the
corresponding period of 1996. Operating income margins increased to 9.6% of
net sales in the nine months ended September 30, 1997 from 8.4% in the
corresponding period of 1996. These increases were attributable to the 25.1%
increase in sales and were offset by increased selling, general and
administrative expenses.
 
  Interest expense increased $1.2 million for the nine months ended September
30, 1997, reflecting borrowings used to fund the Company's redemption of
certain shares of its voting common stock in June 1996. See "Certain
Relationships and Related Transactions--Management Buyout."
 
  Net income increased 49.0% or $4.3 million to $13.1 million for the nine
months ended September 30, 1997 compared to $8.8 million in the corresponding
period of 1996. This increase was due to increased net sales and gross profit
margin and reduced selling, general and administrative expenses as a
percentage of net sales, as noted above.
 
Year Ended December 31, 1996 Compared to Year Ended December 31, 1995
 
  Net sales increased 26.4% or $37.3 million to $178.5 million in 1996
compared to $141.2 million in 1995. This increase was primarily a result of
increased sales of grain storage products resulting primarily from
historically high domestic grain prices, increased sales of swine equipment
resulting primarily from strong construction demand for larger swine
facilities, and increased international sales of swine, poultry and grain
storage equipment resulting primarily from regional market penetration and
successful bids on turn-key grain storage projects.
 
  Gross profits increased to $42.8 million in 1996 or 24.0% of net sales
compared to $26.2 million in 1995 or 18.5% of net sales. The increase in gross
profit reflected the impact of increased sales, as well as the benefit of
price increases in certain product lines, together with operating efficiencies
and the return of certain raw material prices to levels more consistent with
recent historical levels. The positive impacts of the above items were
partially offset by a change in sales mix towards newly-introduced, lower
margin products within the swine product line.
 
 
                                      42
<PAGE>
 
  Selling, general and administrative expenses increased 29.8% or $6.6 million
to $28.8 million in 1996 from $22.2 million in 1995. As a percentage of net
sales, selling, general and administrative expenses increased to 16.1% in 1996
from 15.7% in 1995. These increases were primarily a result of the
introduction of a two-year employee bonus incentive program driven by total
company profitability and increased staffing in the international
sales/engineering functions, partially offset by the elimination of certain
non-essential positions in corporate functions and an increase in distribution
expense.
 
  Operating income increased 250.4% or $10.0 million to $14.1 million for 1996
compared to $4.0 million for 1995. Operating income margins increased in 1996
to 7.9% of net sales in 1996 from 2.8% in 1995. These increases were
attributable to the 26.4% increase in net sales and improved gross margins and
were offset by increased selling, general and administrative expenses.
 
  Interest expense increased $0.7 million for 1996, reflecting additional
borrowings used to fund the Company's redemption of certain shares of its
voting common stock in June 1996. See "Certain Relationships and Related
Transactions--Management Buyout." Interest income was essentially flat in 1996
compared to 1995.
 
  Net income increased $12.0 million to $10.5 million in 1996 compared to a
loss of $1.5 million in 1995. This increase was due to increased operating
income and the negative impact in 1995 of the $3.4 million write-off of an
affiliate receivable. There was no write-off of an affiliate receivable in
1996.
 
Year Ended December 31, 1995 Compared to Year Ended December 31, 1994
 
  Net sales increased 7.9% or $10.3 million to $141.2 million in 1995 compared
to $130.9 million in 1994. This increase was primarily driven by strong
international market penetration for grain storage, swine and poultry
products.
 
  Gross profits increased to $26.2 million in 1995 from $24.8 million in 1994,
representing 18.5% of net sales in 1995 and 19.0% of net sales in 1994. This
decrease in gross profit percentage on slightly higher sales volume reflected
the impact of the aggressive bidding on contracts in the international market.
 
  Selling, general and administrative expenses increased 13.7% or $2.7 million
to $22.2 million in 1995 from $19.5 million in 1994. As a percentage of net
sales, selling, general and administrative expenses increased to 15.7% in 1995
from 14.9% in 1994. These increases were primarily the result of the hiring of
professional staff for focused product grouping support.
 
  Operating income decreased 24.6% or $1.3 million to $4.0 million for 1995
compared to $5.3 million for 1994. Operating income margins decreased to 2.8%
of net sales in 1995 from 4.1% in 1994. These decreases were attributable to
lower margin product mix and increased selling, general and administrative
expenses.
 
  Interest expense increased by $1.0 million for 1995 reflecting expanded
working capital needs. Other expense increased $3.4 million in 1995 due to the
non-recurring write-off of an affiliate receivable.
 
  The Company experienced a loss of $1.5 million in 1995 compared to net
income of $3.0 million in 1994. This loss was due to decreased operating
income and the $3.4 million write-off of an affiliate receivable.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  The Company has historically funded capital expenditures, working capital
requirements, debt service, stockholder dividends and stock repurchases from
cash flow from its operations, augmented by temporary borrowings made under
various credit agreements.
 
 
                                      43
<PAGE>
 
  The Company's working capital requirements for its operations are seasonal,
with investments in working capital typically building in the second and third
quarters and then declining in the first and fourth quarters. As of December
31, 1996, the Company had $15.3 million of working capital, an increase of
$7.2 million from working capital as of December 31, 1995. The increase in
working capital was primarily due to an increase in accounts receivables and a
$10.8 million decrease in short-term debt associated with the repayment of
outstanding bank notes, partially offset by the establishment of a $5.5
million dividend payable. As of September 30, 1997, the Company had working
capital of $33.9 million, as compared to working capital of $15.3 million at
December 31, 1996.
 
  Operating activities generated $1.5 million, $2.4 million and $1.7 million
in cash flow in each of 1994, 1995 and 1996, respectively. The increase in
cash flow from operating activities from 1994 to 1995 of $0.9 million was
primarily a result of a reduction of accounts receivable and lower inventory
purchases of $4.6 million offset by a net loss of $1.5 million recorded in
1995 compared to net income of $3.0 million in 1994. The decrease in cash flow
from operating activities from 1995 to 1996 of $0.7 million was primarily the
result of an increase of accounts receivable and inventories of $4.5 million
and a decrease of accounts payable, accrued expenses and customer deposits of
$4.5 million, offset by net income of $10.5 million in 1996 compared to a net
loss of $1.5 million in 1995.
 
  The Company provided $0.9 million of cash flow for the nine months ended
September 30, 1996, while it used $1.3 million for the nine months ended
September 30, 1997. The $2.3 million decrease in operating cash flow was
primarily the result of the Company's decision to increase inventory levels in
anticipation of customer demand in 1997, partially offset by a $4.3 million
increase in net income for the nine months ended September 30, 1997 compared
to the corresponding period of 1996.
 
  The Company's capital expenditures totaled $10.9 million, $5.8 million and
$3.8 million in 1994, 1995 and 1996, respectively. Capital expenditures have
primarily been for machinery and equipment and the purchase and expansion of
facilities. The Company anticipates that capital expenditures will average
approximately $6.0 million to $7.0 million per year over the next five years.
Other investing activities that resulted in significant cash flow included
$8.0 million in proceeds from the sale of net assets of a discontinued
business, $2.1 million in payments received on notes receivable, and $1.4
million in proceeds from sales of fixed assets, all of which occurred in 1996.
For the nine months ended September 30, 1997, cash used for investing
activities was primarily used for capital expenditures.
 
  Cash provided by financing activities in 1994 and 1995 was $9.2 million and
$3.8 million, respectively. The cash resulted primarily from a net $6.8
million issuance of long-term debt and from $5.8 million of borrowings under
lines of credit in 1994, and $3.5 million in net borrowings under the Bank
Credit Facility in 1995. Cash used in financing activities for 1996 consisted
primarily of $25.5 million for the acquisition of treasury stock partially
offset by $17.5 million in proceeds from the repayment of former stockholder
loans and $2.3 million in proceeds from the issuance of common stock.
 
  The Company acquired the assets of Clark Products, Inc. in February 1997 for
an aggregate purchase price of approximately $1.6 million. The Clark
acquisition was funded primarily through available cash and borrowings under
various credit facilities.
 
  The Company sold the assets of its Heritage Vinyl Products Division in
January 1996 and applied the net proceeds of approximately $8.0 million to
reduce outstanding indebtedness under various credit facilities. The Company
has restated 1994 and prior year financial statements to present continuing
operations without the discontinued operations of the division.
 
  The Company acquired all of the capital stock of DMC for an aggregate
purchase price of $19.3 million on November 5, 1997. The Company funded the
DMC Acquisition with a portion of the net proceeds from the Offering. See "Use
of Proceeds" and "Business--DMC Acquisition."
 
 
                                      44
<PAGE>
 
  The Company plans to continue to pursue a selective acquisition strategy
which may result in the need for additional debt or equity financing in the
future.
 
  Upon consummation of the Offering, approximately 95% of the Company's
indebtedness was repaid with the net proceeds of the Offering. Also, upon
consummation of the Offering, the New Credit Agreement provided a revolving
credit and letter of credit facility of $40 million terminating in November
2000 with no scheduled amortization. Revolving loans under the New Credit
Agreement are available for working capital and general corporate purposes.
See "Description of the New Credit Agreement."
 
  The Company believes that existing cash, cash flow from operations and
available borrowings under the New Credit Agreement will be sufficient to
support its working capital, capital expenditures and debt service
requirements for the foreseeable future.
 
INFLATION
 
  The Company believes that inflation has not had a material effect on its
results of operations or financial condition during recent periods.

                                   BUSINESS
 
INTRODUCTION
 
  The Company is a leading manufacturer and supplier of agricultural equipment
and services worldwide. The Company believes that it is the largest global
provider of both (i) grain storage bins and related drying and handling
systems and (ii) swine feed storage, feed delivery, confinement and
ventilation systems. The Company also is one of the largest global providers
of poultry feed storage, feed delivery, watering, ventilation, nesting, egg-
handling and hatching systems. The Company markets its agricultural products
in approximately 75 countries through a network of over 1,600 independent
dealers to grain, swine and poultry producers primarily under its GSI(R),
AP(TM) and Cumberland(R) brand names. The Company's current market position in
the industry reflects both the strong, long-term relationships the Company has
developed with its customers as well as the quality and reliability of its
products.
 
  Craig Sloan, the Chief Executive Officer of the Company, founded its current
business in 1972. In 1995, the Company recruited additional management and in
1996, all of the capital stock of the Company was acquired by Mr. Sloan and
certain other executives of the Company. The Company's new management-led
ownership has implemented a growth strategy designed to position the Company
as the premier worldwide manufacturer and supplier of high-quality, cost
efficient grain, swine and poultry systems. In addition to capitalizing on
domestic and international growth opportunities, the Company's new management
has focused on profitability, production efficiencies and cost reductions
commenced during 1995. As a result, the Company has experienced rapid growth
in recent years. Net sales and operating income increased from $141.2 million
and $4.0 million, respectively, in 1995 to $178.5 million and $14.1 million,
respectively, in 1996, and were $172.0 million and $16.5 million,
respectively, for the nine months ended September 30, 1997. EBITDA increased
from $7.9 million in 1995 to $17.6 million in 1996, and was $19.2 million for
the nine months ended September 30, 1997. On a pro forma basis after giving
effect to the Offering, the application of the net proceeds therefrom and the
DMC Acquisition, EBITDA would have been $26.9 million for the twelve months
ended September 30, 1997.
 
  The primary users of the Company's grain storage, drying and handling
products are farm operators or commercial businesses, such as the Archer-
Daniels-Midland Company and Cargill, Inc., that operate feed mills, grain
elevators, port storage facilities and commercial grain processing facilities.
The Company believes that its grain storage, drying and handling equipment is
superior to that of its principal competitors on the basis of strength,
durability, reliability, design efficiency and breadth of product offering.
The Company's feeding and ventilation systems are used primarily by growers
that raise swine and poultry, typically on a contract basis for large
integrators such as Murphy Family Farms, Perdue Farms Incorporated and Tyson
Foods, Inc. Because swine and poultry growers are partially compensated by
integrators based on the efficiency with which they convert feed to meat (the
"feed-to-meat ratio"), they seek to purchase systems which minimize the feed-
to-meat ratio. As a result of its proprietary designs, the Company believes
that its swine and poultry systems are the most effective in the industry in
serving this customer objective.
 
  The industry in which the Company operates is characterized both
domestically and internationally by a few large companies, such as the
Company, with broad product offerings and numerous small manufacturers of
niche product lines. Domestically, the Company intends to build on its
established presence in the grain, swine and poultry markets. Internationally,
the Company intends to capitalize on growth opportunities arising from still-
developing agricultural industries and favorable trends in the demand for
grain, poultry and swine products. The Company believes that less functionally
sophisticated and efficient grain storage systems used by facilities located
outside the U.S. and Western Europe, which experience relatively high levels
of grain spoilage and loss, are increasingly likely to be replaced by more
modern systems. The Company also believes that the significant economic and
population growth occurring in the Company's international markets will
continue to result in consumers devoting larger portions of their income to
improved and higher-protein diets, stimulating stronger demand for poultry,
and to a lesser extent, pork. The Company believes that it is well-positioned
to capture expected increases in worldwide demand for its products resulting
from these industry trends because of its leading brand names, broad and
diversified product lines, strong distribution network and high-quality
products. See "--Industry Overview."

  The Company was incorporated in Delaware on April 30, 1964. The Company's
principal executive office is located at 1004 East Illinois Street,
Assumption, Illinois 62510 and its telephone number is (217) 226-4421.
 
COMPANY STRENGTHS
 
  MARKET LEADER. The Company believes that it is the largest global provider
of both (i) grain storage bins and related drying and handling systems and
(ii) swine feed storage, feed delivery, confinement and ventilation systems.
The Company also is one of the largest global providers of poultry feed
storage, feed delivery, watering, ventilation, nesting, egg-handling and
hatching systems. The Company intends to continue to build its market share by
capitalizing on its strong reputation and the growth trends in worldwide
demand for grain, swine and poultry production.
 
  PROVIDER OF FULLY-INTEGRATED SYSTEMS. The Company offers a broad range of
products that permits customers to purchase all of their grain, swine and
poultry production needs from one supplier. The Company believes that
providing fully-integrated systems significantly lowers total production costs
and enhances producer productivity by offering compatible products designed to
promote synergies and achieve maximum operating results. Dealers who purchase
fully-integrated systems also benefit from lower administrative and shipping
costs and the ease of dealing with a single supplier. The Company intends to
maintain its position as a provider of fully-integrated systems by continuing
to offer the most complete line of products available within its markets and
by developing and introducing new products. See "--Products."
 
  BRAND NAME RECOGNITION AND REPUTATION FOR QUALITY PRODUCTS AND SERVICE.
Through its manufacturing expertise and experience, the Company has
established recognition in its markets for the GSI(R), AP(TM) and
Cumberland(R) brand names. The Company seeks to protect the reputation for
high quality, reliability and specialized services that are associated with
such brand names through extensive quality control and customer feedback
programs. The Company believes that its reputation and recognized brand names,
along with its extensive distribution network, will assist it in its efforts
to further penetrate both the domestic and international markets in which the
Company operates.
 
  EFFECTIVE AND ESTABLISHED DISTRIBUTION NETWORK. The Company believes that
its development of a highly effective and established distribution network
affords it significant competitive advantages. The Company's distribution
network consists of over 1,600 independent dealers that market the Company's
products in approximately 75 countries throughout the world. The breadth and
scope of the Company's distribution network makes its products readily
available in each of the Company's markets and lowers transportation costs for
its customers. Dealers are carefully selected and trained to ensure high
levels of customer service. In addition, the Company has experienced a very
low turn-over rate of its dealers since the Company's inception, which
promotes consistency and stability to customers. See "--Product Distribution."
 
  LONG-TERM ALLIANCES WITH CUSTOMERS. The Company has a history of developing
long-term alliances with customers who are market leaders in both the
industries and the geographic markets they serve. The Company works closely
with customers through all stages of product development in order to tailor
products and systems to meet each customer's unique needs, making
substitutions with competitor products more difficult. The Company's
commitment to product quality, dedication to customer service and
responsiveness to changing customer needs have enabled the Company to develop
and strengthen long-term alliances with its customers. The strength of the
Company's customer relationships are demonstrated by the fact that over 45% of
the Company's 1996 domestic net sales derived from grain equipment were made
to customers who have purchased from the Company for at least 10 years. In
addition, the Company has entered into long-term supply agreements with two of
its largest customers, which arrangements the Company believes are unique in
the industry.
 
  FLEXIBLE MANUFACTURING FACILITIES. The Company's facilities are designed to
be easily reconfigured to adapt to demand changes for any or all of the
Company's products. The Company's primary manufacturing facility, located in
Assumption, Illinois, consists of approximately 675,000 square feet and
operates on a 24-hour basis during peak production periods. The Company's
facilities employ state-of-the-art machines that have enhanced

production efficiency. The Company believes that its current facilities will
accommodate planned production increases as the Company experiences sales
growth and expands into new markets. See "--Facilities."
 
  COMPANY OPERATED AND OWNED BY EXPERIENCED MANAGEMENT TEAM. The Company is
led by an experienced management team, the members of which have each worked
in the agricultural products industry for an average of 16 years. Craig Sloan,
a founder and the Chief Executive Officer of the Company, and each of the
other members of the Company's senior management team have invested in the
Company and together own all of its voting common stock. The Company believes
that the agricultural expertise of its management team, coupled with the
corporate culture promoted by a management-owned company, permit it to
establish strong customer relationships and respond quickly to market
opportunities. See "Management--Executive Officers and Directors" and
"Ownership of Capital Stock."
 
BUSINESS STRATEGY
 
  The Company's objective is to capitalize on its strengths through the
implementation of its business strategy, which includes the following
principal elements:
 
  CAPITALIZE ON GROWTH OPPORTUNITIES IN INTERNATIONAL MARKETS. International
sales increased from approximately $36.8 million in 1995 to approximately
$55.5 million in 1996, and were approximately $43.5 million in the nine months
ended September 30, 1997. The Company intends to continue to leverage its
worldwide brand name recognition, leading market positions and international
distribution network to capture the significant demand for its products that
exists in the international marketplace. While the Company anticipates that
sales will continue to be generated worldwide, the Company is targeting the
Far East, Latin America and Eastern Europe, where it believes the greatest
potential for significant growth exists. The Company believes that increasing
the diversity of both its customer base and geographic coverage by expanding
its international operations will mitigate the effect of future reductions in
demand within any of its individual product lines, or within a particular
geographic selling region.
 
  ENHANCE GROWTH THROUGH STRATEGIC ACQUISITIONS. The Company will continue to
selectively seek acquisitions with complementary product lines that offer the
opportunity to improve market penetration and profitability through
integration with the Company's existing businesses. The Company believes that
the markets in which it operates include single-product producers who may not
be able to effectively compete against larger integrated producers, such as
the Company, but which might benefit from economies of scale resulting from a
business combination with the Company. The Company recently acquired all of
the capital stock of DMC, a leading manufacturer and supplier of grain drying
and handling equipment, to complement the Company's grain equipment product
line.
 
  CONTINUE DEVELOPMENT OF PROPRIETARY PRODUCT INNOVATIONS. The Company's
research and development efforts focus on the development of new and
technologically advanced products to respond to customer demands, changes in
the marketplace and new technology. The Company employs a strategy of working
closely with its customers and capitalizing on existing technology to improve
existing products and develop new value-added products. The Company believes
that it has an impressive record of new product development as is evidenced by
its improved Easy Access doors and Series 2000 dryers for grain bins, its
Performer Fan(TM) line of products for the swine industry and its patented HI-
LO(R) chicken feeders and Delta Series(TM) turkey feeders. The Company intends
to continue to actively develop product improvements and innovations to more
effectively serve its customers. See "--Products."
 
  CONTINUE PROFITABILITY ENHANCEMENTS. The Company plans to continue to
actively manage its business to improve cash flows by containing costs,
selectively expanding production and improving productivity. The Company's
past success in enhancing profitability is evidenced by an EBITDA margin for
1996 of 9.9% compared to 5.6% for 1995, and an EBITDA margin of 11.1% for the
nine months ended September 30, 1997 compared to 10.3% for the corresponding
period in 1996.
 
 
                                      48
<PAGE>
 
DMC ACQUISITION
 
  In furtherance of its business strategy, the Company, on November 5, 1997,
acquired all of the capital stock of DMC for approximately $19.3 million in
cash. The Company funded the DMC Acquisition with a portion of the net
proceeds from the Offering. See "Use of Proceeds."
 
  DMC is a leading manufacturer and supplier of grain drying and handling
equipment. DMC manufactures equipment at its headquarters in Mason City, Iowa
and maintains six company-owned distribution facilities in Iowa, Nebraska,
Illinois, Arkansas, Indiana and South Dakota. DMC uses this distribution
network to market products to approximately 1,500 domestic and international
dealers. DMC recorded net sales and operating income of $26.0 million and $3.7
million, respectively, for the eleven months ended September 30, 1997.
Approximately 52% of DMC's net sales during such period were derived from
products manufactured by DMC, with the remaining portion derived from
products, including augers, fans, heaters, floor supports and bucket elevators
and conveyors, that were purchased from manufacturers other than the Company.
International sales comprised approximately 13.5% of DMC's net sales for the
eleven months ended September 30, 1997.
 
  The Company believes that the DMC Acquisition has expanded the breadth of
the Company's grain equipment product line and will increase net sales and
operating income. Because the Company manufactures many of the products sold
but not manufactured by DMC, the Company supplies such products to DMC. The
Company will continue to leverage DMC's distribution network to increase sales
of the Company's swine equipment. In addition, the Company believes it can
increase sales of DMC products through dealers in the Company's distribution
network who currently handle products of competitors of DMC.
 
INDUSTRY OVERVIEW
 
  Demand for the Company's products is driven by the overall worldwide level
of grain, swine and poultry production as well as the increasing focus both
domestically and internationally on improving productivity in these
industries. These markets are driven by a number of factors, including
consumption trends affected by economic and population growth and government
policies.
 
  Demand for grain and the required infrastructure for grain storage, drying
and handling is driven by several factors, including the need for additional
grain for increased worldwide production of swine, poultry and beef. The
Company believes that less functionally sophisticated and efficient grain
storage facilities located outside the U.S. and Western Europe, which
experience higher levels of grain spoilage and loss, are increasingly likely
to be replaced by more modern equipment. The Company also believes that these
dynamics will continue to support rising domestic and international demand for
the Company's grain storage, drying and handling systems.
 
  Demand for the Company's swine and poultry feeding equipment and feed
storage and delivery systems is positively impacted by the significant
economic and population growth occurring in certain international markets,
including Asia (where average annual gross domestic product growth rates over
the past ten years have been more than triple that of the U.S.), Latin America
and to a lesser extent, Eastern Europe. As a result of increasing disposable
income in these international markets, consumers are devoting larger portions
of their income to improved and higher protein-based diets. This has
stimulated stronger demand for meat, specifically poultry and, to a lesser
extent, pork, as these meats provide more cost-effective sources of animal
protein than beef.
 
  The Company's sales of grain equipment have historically been affected by
feed and grain prices, acreage planted, crop yields, demand, government
policies, government subsidies and other factors beyond the Company's control.
Weather conditions also can adversely impact the agricultural industry and
delay planned construction activity, resulting in fluctuating demand for the
Company's grain equipment and delayed or lost revenues. Increases in feed and
grain prices have in the past resulted in a decline in sales of feeding,
watering and ventilation systems, although these same conditions have tended
to improve sales of grain storage bins. The Company's sales of swine and
poultry equipment historically have been affected by the level of construction
activity by swine and poultry producers, which is affected by feed prices and
domestic and international demand for pork and poultry. See "Risk Factors--
Agricultural Industry; Seasonality."

 GRAIN INDUSTRY
 
  After several years of relatively slow growth, world grain production is
projected to increase more rapidly through 2005 to meet demand for grain
products. Widespread economic and population growth, which increases demand
for animal protein, is driving increased demand for world grain production.
The U.S. Federal Agricultural Improvement and Reform (FAIR) Act of 1996 and
continued crop yield enhancements are expected to permit increased worldwide
grain production to meet this demand. According to the United States
Department of Agriculture (USDA), increasing demand for grain, combined with a
shortage of crops due to poor weather in key growing regions in the last
several years, resulted in a tightening of inventory positions and the lowest
level of U.S. and worldwide grain reserves in recent history. Consequently,
grain prices have risen both in real and nominal terms over the last several
years, while also creating significant pricing volatility and variability
beyond the normal seasonal variations. Higher grain prices have greatly
increased the income and cash reserves of North American grain farmers
providing them with the means to invest in additional farm assets. Commodity
price variations provide incentives for grain producers and users to utilize
on-farm or commercial grain storage capacity to take advantage of favorable
points in the pricing cycle.
 
 PORK INDUSTRY
 
  Although U.S. pork production has experienced slow growth over the past 10
years, a recent trend towards industry consolidation from a large number of
small operators to a smaller number of larger, integrated operators is
creating increased demand for automated production systems including feeding
and ventilation systems. Since 1980, the number of U.S. swine farms has fallen
from over 650,000 to under 200,000. Total U.S. pork production, however, has
increased from 14.0 billion pounds in 1986 to 17.1 billion pounds in 1996, due
in part to greater capital investment in automated systems by larger
operators. The Company believes that this consolidation is likely to further
lower production costs and therefore pork prices, which may have a favorable
impact on per capita pork consumption. Internationally, world pork production
is projected to grow at a rate of 2.8% per year from 1997 to 2000. The primary
growth areas for pork demand are expected to include Asia and Mexico with
growth also anticipated in the countries of the former Soviet Union and
central and eastern Europe. The Company believes that much of the production
is expected to shift from small unconfined manual facilities to more modern
automated, confined facilities, and to large U.S. swine integrators that
establish overseas facilities, resulting in lower production costs and
improved meat quality.
 
 POULTRY INDUSTRY
 
The U.S. poultry industry has enjoyed steady growth over the past several
decades, with U.S. per capita consumption of poultry increasing from 42.8
pounds in 1975 to 90.1 pounds in 1996, a compound annual growth rate of 3.6%.
U.S. poultry production has grown annually at rates of between 5% and 7% over
the past decade and this trend is expected to continue into the foreseeable
future. World poultry production and consumption have grown at even greater
rates than the U.S. in the last two decades. Industry sources attribute these
increases to a number of factors, including consumers' rising disposable
incomes, population growth, declining relative prices of poultry to other
meats and product innovations such as the proliferation of pre-packaged and
value-added poultry products. Additionally, nutritional and health concerns
among consumers have led to poultry market share increases relative to red
meat due to poultry's relatively low fat, low cholesterol and high protein
content. International growth is projected to exceed the rate experienced in
the U.S. due to the rapid rate of international economic development and the
relatively low market share that poultry holds of the total meat market in a
number of developing countries. As a result of this growth to date and the
inability of a number of developing countries to increase their production
facilities at a like rate, U.S. broiler exports have grown at a compound
annual rate of 25% since 1985, with global poultry trade projected to grow at
approximately 4% annually through 2005. Consequently, the U.S. is now the
world's largest exporter of poultry and is expected to hold this position for
the foreseeable future. Despite steady growth in both domestic and
international poultry production and consumption, competitive pressures have
caused poultry equipment prices to decline and the market for poultry
equipment products has not expanded as rapidly. See "Risk Factors--
Competition."

Company manufactures and markets a complete line of over 100 models of grain
drying devices with capacities of up to 10,000 bushels per hour. The Company
markets its grain drying equipment to both farm and commercial end users under
its GSI(R) and Airstream(R) brand names. The Company's drying equipment, which
includes fans, heaters, top dryers, portable dryers, stack dryers and tower
dryers, are manufactured using galvanized steel and high-grade electrical
components and utilize patented control systems, which offer computerized
control of all dryer functions from one panel.
 
  Grain Handling Equipment. During 1997, the Company began manufacturing and
marketing a complete line of grain handling equipment to complement its grain
storage and drying product offerings. The Company markets its grain handling
equipment, which includes bucket elevators, conveyors and augers, to both farm
and commercial end users under its GSI(R) brand name. The Company's grain
handling equipment offers ease of integration into Company or competitor
systems and enables the Company to offer a fully-integrated product line to
grain producers.
 
 SWINE PRODUCT LINE
 
  The Company's swine equipment consists of the following products:
 
  Feeding Systems. The Company manufactures and markets its swine feeding
products under its AP(TM) brand name. The Company designs and implements
custom swine feeding systems to fit both the general industry needs of the
different types of swine producers and the specialized needs of individual
swine producers. The Company's swine feeding systems generally consist of a
feed storage bin located outside of the swine building and a feed delivery
system, which conveys the feed to and through the building to drop feed
dispensers suspended within the building. The drop feed dispensers provide
individualized feeding through automatic timers. The Company's swine feed
storage bins are manufactured with precision die-cut, high tensile corrugated
steel and assembled with an exclusive water tight sealing system and specially
die-formed eaves, and include the Auto-Lok(TM) access system, which allows for
efficient systems monitoring. The Company's swine feed delivery systems
consist of the Flex-Flo(TM) System and the Chain Disk System. The Flex-Flo(TM)
System uses high-quality
 
                                      51
<PAGE>
 
tensile steel augers and precision control devices to reach all drop feeders
within a system. The Chain Disk System handles high capacities of feed at long
distances with multiple turns. The Company believes that its swine drop
feeders are superior to its competitors' products due to their ease of
installation and maintenance, ability to handle high volumes of feed, accurate
eye-level scales and strong, durable all-plastic construction that eliminates
corrosion.
 
  Ventilation Systems. The Company manufactures and markets ventilation
systems for swine buildings under its AP(TM) and Airstream(R) brand names.
These systems consist of fans, heating and evaporative cooling systems,
winches, inlets and other accessories (including computer based automated
control devices) that regulate temperature and air flow. Proper ventilation
systems are crucial for minimizing the feed-to-meat conversion ratio by
reducing stress caused by extreme temperature fluctuation, allowing for higher
density production and providing optimum swine health through disease
prevention. The Company's swine ventilation systems produce high levels of air
output at low levels of power consumption, adapt to a wide array of specialty
fans and other accessories, operate with little maintenance or cleaning and
provide precision monitoring of environmental control.
 
  Confinement Systems. The Company manufactures and markets confinement
systems for swine buildings under its AP(TM) brand name. These systems consist
of products for building pens, gates, inner dividing walls and flooring
systems, special heating systems for piglets and uniquely designed gestation
stalls. The Company's swine confinement systems are manufactured using high
tensile steel, and utilize advanced robotic welding, shot blasting and
electrostatic spraying techniques to assure a long-lasting finish that is
durable, corrosion resistant and easy to clean. The Company believes its swine
confinement products contain several design ingenuities. Two examples are the
Company's Hog-Hearth System, which provides heat to newborn piglets at lower
energy costs than are otherwise required in more conventional heating methods,
and the Company's plastic swine nursery flooring equipment, which provides
extra comfort for growing piglets and cleaning advantages for swine producers.
 
 POULTRY PRODUCT LINE
 
  The Company's poultry equipment consists of the following products:
 
  Feeding Systems. The Company manufactures and markets its poultry feeding
systems under its Cumberland(R) brand name. The Company manufactures feeding
systems that are custom tailored to both the general industry needs of
different types of poultry producers and to the specialized needs of
individual poultry producers. The Company's poultry feeding systems consist of
a feed storage bin located outside the poultry house, a feed delivery system
that delivers the feed from the feed storage bin into the house and an
internal feed distribution system that delivers feed to the birds. The
Company's poultry feed storage bins contain a number of patented features
designed to maximize capacity, manage the quality of stored feed, prevent rain
and condensation from entering feed storage bins and provide first-in, first-
out material flow, thereby keeping feed fresh to prevent spoilage, and blended
to provide uniform quality rations. The Company's poultry feed delivery
systems use non-corrosive plastic and galvanized steel parts specially
engineered for durability and reliable operations and specialized tubing and
auguring or chain components that allow feed to be conveyed up, down and
around corners. The Company believes that its patented HI-LO(R) pan feeder is
superior to competitor products due to its unique ability to adjust from floor
feeding for young chicks to regulated feed levels for other birds.
 
  Watering Systems. The Company manufactures and markets nipple watering
systems for poultry producers under its Cumberland(R) brand name. The ability
of a bird to obtain water easily and rapidly is an essential factor in
facilitating weight gain. The Company's poultry watering system consists of
pipes that distribute water throughout the house to drinking units supported
by winches, cables and other components. The water is delivered through a
regulator designed to provide differential water pressure according to demand.
The Company's poultry watering systems are distinguished by their toggle
action nipples, which transmit water from
 
                                      52
<PAGE>
 
nipple to beak without causing undue stress on the bird or excess water to be
splashed onto the floor. The watering nipples produced by the Company also are
designed to allow large water droplets to form on the cavity of the nipple,
thereby attracting young birds to drink, which ultimately promotes weight
gain.
 
  Ventilation Systems. The Company manufactures and markets ventilation
systems for poultry producers under its Cumberland(R) brand name. Equipment
utilized in such systems include fiberglass and galvanized fans, the Komfort
Kooler evaporative cooling systems, manual and automated curtain coolers,
heating systems and automated controls for complete ventilation, cooling and
heating management. The Company believes its poultry ventilation products are
reliable and easy to assemble in the field, permit energy-efficient airflow
management and are well-suited for international sales because they ship
compactly and inexpensively and assemble with little hardware and few tools.
 
  Nesting and Egg-Handling Systems. The Company manufactures and markets
nesting and egg-handling systems for poultry producers under its Cumberland(R)
brand name. These systems consist of mechanical nests and egg collection
tables. The Company's nesting and egg-handling systems are manufactured using
high-yield, high tensile galvanized steel and are designed to promote comfort
for nesting birds and efficiency for production personnel. The Company
believes that its nesting and egg-handling systems are among the most reliable
and cost-effective in the poultry industry.
 
  Hatching Systems. The Company manufactures and markets commercial incubation
systems for the poultry industry, with capacities of up to 115,200 eggs, under
its Cumberland(R) brand name. The Company provides incubation systems for
producers that grow each of the following types of poultry: breeders (chickens
grown to lay eggs); broilers (chickens grown for human consumption); and
turkeys. The Company believes that its incubation products are distinguished
by their efficient use of space, reliable control panels, effective airflow
mechanisms, versatility and durability, ease of access and sophistication of
tracking devices. The Company's Visionlink(TM) product allows incubators to be
managed from a personal computer, while its Tracer(TM) product facilitates
effective bar code tracing from the point of breeding to the point of
delivery.
 
  In 1996, 1995 and 1994, no single class of the Company's products accounted
for 10% or more of the Company's net sales.
 
PRODUCT DISTRIBUTION
 
  The Company distributes its products primarily through a network of over
1,600 U.S. and international independent dealers who offer targeted geographic
coverage in key grain, swine and poultry producing markets throughout the
world. The Company's dealers sell products to grain, swine and poultry
producers, agricultural companies and various other farm and commercial end-
users. The Company believes that its distribution network is one of the
strongest in the industry, providing its customers with high levels of
service. Since its inception, the Company has experienced a very low turn-over
rate of its dealers. The Company believes this has resulted in a reputation of
consistency in its products and stability with its customers. The Company
further believes that the high-level of commitment its dealers have to the
Company is evidenced by the fact that many of the Company's dealers choose not
to sell products of the Company's competitors.
 
  The Company also maintains a sales force consisting of approximately 75
professionals. In addition to providing oversight services of the Company's
distribution network, the sales force interacts with integrators and end
users, recruits additional dealers for the Company's products, and educates
the dealers on the uses and functions of the Company's products. The Company
further supports and markets its products with a 27 person technical service
and support team, which provides training and advice to dealers and end users
regarding installation, operation and service of products and, when necessary,
on-site service.
 
  In 1996 no individual dealer or other customer represented more than 10% of
the Company's net sales.
 
 DOMESTIC DISTRIBUTION AND CUSTOMERS
 
  The Company sells its products in the U.S. through a network of over 1,350
independent dealers who market, sell and, in many cases, install the Company's
products and provide post-sale technical support and service. Most of the
Company's domestic sales are made to dealers who market the Company's products
to
 
                                      53
<PAGE>
 
grain, swine and poultry end-users. The Company also makes direct sales of its
products to end-users, such as large commercial grain producers or swine or
poultry "turn-key" contractors. The Company's domestic dealers generally cover
certain geographic areas but are not restricted from competing in other
geographic markets.
 
 INTERNATIONAL DISTRIBUTION AND CUSTOMERS
 
  The Company has more than 250 independent international dealers that market
the Company's products in approximately 75 countries outside of the U.S. The
Company prefers to sell its products to local dealers, while maintaining the
right to make direct sales to key international customers. When direct sales
are made the Company provides engineering and construction management support.
The Company's international dealers generally represent specific geographic
areas and are responsible for the development of their respective markets and
dealer networks. While the Company anticipates that sales will continue to be
generated worldwide, the Company is targeting the Far East, Latin America and
Eastern Europe, where it believes the greatest potential for significant
growth exists.
 
  The percentage of net sales generated by the Company by market region in
1994, 1995 and 1996 were as follows:

COMPETITION
 
  The market for the Company's products is competitive. Domestically and
internationally, the Company competes with a variety of manufacturers and
suppliers that offer only a limited number of the products offered by the
Company. The Company believes that only one of its competitors, CTB
International Corp., offers products across most of the Company's product
lines. See "Risk Factors--Competition."
 
  Competition is based on the price, value, reputation, quality and design of
the products offered and the customer service provided by distributors,
dealers and manufacturers of the products. The Company believes that its
leading brand names, diversified product lines, strong distribution network
and high quality products enable it to compete effectively. The Company
further believes that its ability to offer integrated systems to grain, swine
and poultry producers, which significantly lowers total production costs and
enhances producer productivity, provides it with a competitive advantage.
Integrated equipment systems offer significant benefits to dealers, including
lower administrative and shipping costs and the ease of dealing with a single
supplier for all of their customer needs. In addition, the Company's dealers
provide producers with high quality service, installation and repair.
 
NEW PRODUCT DEVELOPMENT
 
  The Company has a product development and design engineering staff of
approximately 45 people, most of whom are located in Assumption, Illinois.
Expenditures by the Company for product research and development amounted to
approximately $1.3 million, $1.4 million and $1.1 million for the years ended
December 31, 1996, 1995 and 1994, respectively. The Company charges research
and development costs to operations as incurred. The Company anticipates
product research and development spending to continue at historic levels for
the foreseeable future.

RAW MATERIALS
 
  The primary raw materials used by the Company to manufacture its products
are steel and polymer materials, including PVC pipe, polypropylene and
polyethylene. The Company also purchases various component parts that are
integrated into the Company's products. The Company is not dependent on any
one of its suppliers and in the past has not experienced difficulty in
obtaining materials or components. In addition, materials and components
purchased by the Company are readily available from alternative suppliers. The
Company has no long-term supply contracts for materials or components. See
"Risk Factors--Raw Materials Price Volatility."
 
REGULATORY AND ENVIRONMENTAL MATTERS
 
  Like other manufacturers, the Company is subject to a broad range of
federal, state, local and foreign laws and requirements, including those
governing discharges to the air and water, the handling and disposal of solid
and hazardous substances and wastes, the remediation of contamination
associated with releases of hazardous substances at the Company's facilities
and offsite disposal locations, workplace safety and equal employment
opportunities. Expenditures made by the Company to comply with such laws and
requirements historically have not been material. See "Risk Factors--
Regulatory and Environmental Matters."

(1) Immediately following the consummation of the Offering, the Company used a
    portion of the net proceeds from the Offering to purchase this facility
    from Carolina Agri-Systems, Inc. for approximately $1.3 million. See "Use
    of Proceeds" and "Certain Relationships and Related Transactions--
    Transactions with Carolina Agri-Systems, Inc. and FarmPRO, Inc."
(2) Upon consummation of the Exchange Offer, the Company's owned facilities
    will remain subject to mortgages. The Company's leased facilities are
    subject to various leases that expire between April 1, 1998 and July 1,
    2000.
 
  The Company believes that its facilities are suitable for their present and
intended purposes and have adequate capacity for the Company's current levels
of operation.

BACKLOG
 
  Backlog is not a significant factor in the Company's business because most
of the Company's products are delivered within a few weeks of their order. The
Company's backlog at September 30, 1997 was $26.0 million compared to $20.3
million at September 30, 1996. The Company believes that all such backlog will
be filled by the end of 1997.
 
PATENTS AND TRADEMARKS
 
  The Company protects its technological and proprietary developments. The
Company currently has 21 active U.S. patents and 18 U.S. trademarks. The
Company has been granted a license from Petersime NV, a Belgium Corporation,
for technical information and know-how in developing and manufacturing
incubators for poultry. See "Business--Products--Poultry Product Line--
Hatching Systems." While the Company believes its patents, trademarks and
licensed information have significant value, the Company does not believe that
its competitive position or that its operations are dependent on any
individual patent or trademark or group of related patents or trademarks.
 
PRODUCT LIABILITY AND LEGAL PROCEEDINGS
 
  From time to time, the Company is involved in various litigation matters
involving ordinary and routine claims incidental to the Company's business.
Products sold by the Company may expose it to potential liabilities for
personal injury or property damage claims relating to the use of such
products. The Company maintains third-party product liability insurance which
it believes to be adequate. To date the aggregate costs to the Company for
claims, including product liability actions, have not been material. See "Risk
Factors--Product Liability Risk."
 
  There are no legal proceedings pending against the Company which, in the
opinion of management, would have a material adverse effect on the Company's
business, financial position or results of operations.
 
EMPLOYEES
 
  As of September 30, 1997, the Company had approximately 1,455 employees, of
which 1,124 were permanent and 331 were seasonal. None of the Company's
employees are represented by a union. Management believes that its
relationships with the Company's employees are good.
 
  In July 1996, certain employees of the Company were granted individual
amounts of "gainshares" based on several factors, including experience and
responsibilities. This program, which terminates December 31, 1997, provides
for participating employees to receive 40% of the Company's pre-tax profits
that are in excess of 5% of the Company's net sales. Each participating
employee's portion is calculated based on the number of shares held. Total
expenses to the Company under this plan in 1996 were $2.3 million.

EMPLOYMENT AGREEMENTS
 
  The Company has entered into employment agreements with Messrs. Sloan,
Andrade, Funk and Buffett (each, an "Executive"). The terms of each
Executive's employment agreement are substantially the same. Each agreement
provides for a specified minimum annual base salary, subject to increases
determined by the Company's Board of Directors, and participation in any
profit sharing, retirement, insurance or other benefit plans maintained by the
Company.
 
  The employment agreement of each Executive will terminate as of the earliest
of: (i) June 6, 2001; (ii) the last day of the month in which the Executive's
death occurs; or (iii) ninety days after the date the Company gives the
Executive notice of termination if such termination is for "cause" or due to
the Executive being "permanently disabled" (as such terms are defined in the
employment agreement). The Company may not terminate an Executive, with or
without cause, unless such termination has been authorized by a resolution
adopted by the Board at a meeting duly called and held, and where the
Executive is given prior written notice of the basis for his termination and
an opportunity to be heard by the Board at such meeting. In addition, the
Executive may not be terminated for cause unless: (i) the Company has followed
the foregoing procedures and (ii) the Executive is given an opportunity to
cure any of the actions or omissions which form the basis for his termination
within 30 days of the adoption of the Board resolution described above. If
employment is terminated due to permanent disability, the Executive will
continue to receive an annual salary (less any benefits paid during the period
of his disability under the Company's disability insurance programs) and other
benefits until such time that the Executive sells his stock to the Company
pursuant to the terms of certain stockholder agreements among the holders of
the Company's voting stock. See "Certain Relationships and Related
Transactions--Management Buyout--Stockholder Agreements." If employment is
terminated without cause after December 6, 1999, the Executive will receive,
immediately upon such termination, a severance payment based on his 1996
salary.
 
  Each employment agreement also provides that during the Executive's
employment with the Company, and for two years thereafter, the Executive will
not be employed by or otherwise engage in any business that is in competition
with the Company, except that the Executive may: (i) invest in such a business
where the stock of such business is traded on a national securities exchange
and the Executive owns less than 1% of the equity of
 
                                      59
<PAGE>
 
such business; (ii) serve on the board of directors of any corporation on
which the Executive is serving as of the date of his termination; and (iii)
invest in any business in which the Executive has an investment as of the date
of his termination. If the Executive is terminated by the Company without
cause, the foregoing covenant not to compete is null and void.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
  The Company did not have a Compensation Committee during 1996. All members
of the Company's Board of Directors participated in deliberations regarding
executive officer compensation during 1996. See "Certain Relationships and
Related Transactions." During 1996, no member of the Company's Board of
Directors served as a director or a member of the compensation committee of
any other company of which any executive officer served as a member of the
Company's Board of Directors.
 
DIRECTOR COMPENSATION
 
  Each director of the Company will receive an annual fee of $10,000 plus a
fee or $5,000 for each Board of Directors meeting attended, with such
attendance fees being capped at $40,000, in the aggregate, per year.

                CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
MANAGEMENT BUYOUT
 
  Prior to June 1996, the Company was owned by Larry Sloan, an uncle of Craig
Sloan, and by Craig Sloan, Tom Sloan and Jim Sloan, all of whom are brothers.
In June 1996, Craig Sloan and three other executives of the Company acquired
all of the Company's voting stock (the "Management Buyout"). The Management
Buyout generally consisted of a redemption by the Company of certain shares of
its voting stock and a subsequent purchase of shares by certain executives of
the Company. In connection with the Management Buyout, the new owners of the
Company's stock also entered into certain stock restriction and buy-sell
agreements. The various components of the Management Buyout are described in
more detail in the sections that follow.
 
                                      60
<PAGE>
 
 REDEMPTION AGREEMENTS
 
  In May 1996, the Company entered into Stock Redemption Agreements with Larry
Sloan, Tom Sloan and Jim Sloan (the "Selling Stockholders") pursuant to which
the Company agreed to redeem all the Selling Stockholders' capital stock (the
"Redemption"). The aggregate purchase price paid by the Company for stock
purchased in the Redemption was $25,490,444, which consisted of payments of
$15,600,000, $5,264,357 and $4,626,087 to Larry Sloan, Tom Sloan and Jim
Sloan, respectively. The purchase price consisted of (i) notes (the
"Stockholder Notes") totaling $17,490,444 issued by the Company to Larry
Sloan, Tom Sloan and Jim Sloan in amounts of $10,600,000, $2,264,357 and
$4,626,087, respectively, and (ii) cash totaling $8,000,000, which consisted
of payments to Larry Sloan and Tom Sloan of $5,000,000 and $3,000,000,
respectively. The Stockholder Notes, which bear interest at 8% and mature on
either May 1, 2002 or May 1, 2006, will be repaid at a discount with a portion
of the net proceeds to the Company from the Offering. See "Use of Proceeds."
Immediately following the Redemption, Craig Sloan became the sole stockholder
of the Company, owning 1,125,000 shares of voting common stock and 200,000
shares of newly issued non-voting common stock.
 
 STOCK PURCHASE AGREEMENTS
 
  In June 1996, the Company entered into Stock Purchase Agreements with Craig
Sloan, the Company's Chief Executive Officer, Jorge Andrade, the Company's
Chief Operating Officer, John W. Funk, the Company's Chief Financial Officer,
General Counsel and Secretary, and Howard G. Buffett, the Company's Chairman
of the Board, pursuant to which such individuals purchased from the Company an
aggregate of 675,000 shares of the Company's voting stock for a total cash
purchase price of $2,250,000. Pursuant to such Stock Purchase Agreements,
Jorge Andrade purchased 300,000 shares for $1,000,000, John W. Funk purchased
225,000 shares for $750,000, Howard G. Buffett purchased 100,000 shares for
$333,333, and Craig Sloan purchased 50,000 shares for $166,667. Upon
completion of such purchases, Craig Sloan, Jorge Andrade, John W. Funk and
Howard G. Buffett (collectively the "New Stockholders") owned 100% of the
Company's capital stock.
 
 STOCK PLEDGE, SUBORDINATION AND GUARANTEE AGREEMENTS
 
  To fund a portion of the $8,000,000 in cash payments made in connection with
the Redemption by the Company to Larry Sloan and Tom Sloan, the Company
obtained a $4,000,000 term loan (the "Loan") from the Bank. In order to (i)
induce the Bank to make the Loan, (ii) encourage the Selling Stockholders to
sell their stock in the Redemption and (iii) obtain necessary consents for the
Redemption from various other creditors of the Company, the Selling
Stockholders, the Company, the Bank, the New Stockholders and various other
creditors of the Company entered into various Stock Pledge Agreements,
Subordination Agreements and Guarantees under which (i) the New Stockholders
pledged all their stock (the "Collateral") to the Bank to secure the Company's
obligations under the Loan, (ii) the New Stockholders pledged an applicable
percentage of the Collateral to each of the Selling Stockholders to secure the
Company's obligations under each of the Stockholder Notes, (iii) the Selling
Stockholders agreed to subordinate their rights to their proportionate shares
in the Collateral to the Bank's rights in the Collateral and (iv) the Selling
Stockholders agreed to subordinate their rights to payments under the
Stockholder Notes to both the rights of the Bank to payments under the Loan
and to the rights of various other creditors to payments from the Company
under certain other credit facilities. Upon consummation of the Offering and
application of the net proceeds therefrom, the pledges of Collateral by the
New Stockholders to the Bank and the Selling Stockholders terminated. See "Use
of Proceeds."
  In connection with the Redemption, each of Craig Sloan, Jorge Andrade and
John Funk also (i) made personal guarantees of certain obligations of the
Company to various creditors and (ii) entered into Indemnification and
Guarantee Agreements with each of the Selling Stockholders whereby such
individuals agreed to indemnify each of the Selling Stockholders for losses
arising from guarantees made by the Selling Stockholders of certain
obligations of the Company and its affiliates to certain creditors of the
Company and its affiliates that did not release the Selling Stockholders from
their obligations under such guarantees.

 STOCKHOLDER AGREEMENTS
 
  In connection with the Management Buyout, the Company and the New
Stockholders entered into a Stock Restriction and Buy-Sell Agreement and the
New Stockholders entered into a Stock Restriction and Cross Purchase Agreement
(the "Stockholder Agreements"). The Stockholder Agreements define the rights
of the New Stockholders with respect to their ownership of the Company's
shares. These agreements generally (i) provide that the holders of a majority
of the stock may sell all of their shares at any time if the other New
Stockholders are entitled to participate in such sale on the same terms and
conditions, and that the holders of a majority of the stock may require the
other New Stockholders to sell all their stock at the same time on the same
terms and conditions, (ii) establish that the New Stockholders are restricted
in their ability to sell, pledge or transfer such shares, (iii) grant rights
of first refusal, first to the Company and then to all non-transferring
stockholders, with respect to the transfer of any shares, (iv) require that an
affirmative vote by a majority of the Company's voting stock is required to
approve certain corporate matters and (v) establish procedures for the
purchase of shares by the Company (subject to compliance with the terms of the
Indenture) or any remaining New Stockholders upon the death, permanent
disability or termination of employment of any New Stockholder. Each of the
New Stockholders is covered by life insurance policies, the proceeds of which
generally will be used to fund the purchase of shares from the estate of a
deceased New Stockholder. The Stockholder Agreements also (i) provide that the
holders of a majority of the Company's shares may cause the Company to
register their shares in an underwritten public offering and (ii) grant piggy-
back registration rights to the New Shareholders in the event of an
underwritten public offering.
 
  In addition, the Company, the New Stockholders and each of the holders of
the Company's non-voting common stock have entered into an agreement that (i)
provides that the holders of non-voting common stock are entitled to sell
their shares on the same terms and conditions in the event the New
Stockholders transfer a majority of the voting stock, (ii) provides that the
holders of the non-voting common stock must under certain circumstances agree
to sell their shares on the terms and conditions approved by the Company's
Board of Directors, (iii) establishes that the holders of the non-voting
common stock are restricted in their ability to sell, pledge or transfer such
shares, (iv) grants rights of first refusal, first to Mr. Sloan and then to
the other New Stockholders, with respect to the transfer of any non-voting
common stock to other non-voting stockholders and (v) establishes procedures
for the purchase of shares by Mr. Sloan, the other New Stockholders and the
Company (subject to compliance with the terms of the Indenture) upon the
death, permanent disability or termination of employment of any holder of non-
voting common stock. The agreement also grants piggy-back registration rights
to the holders of non-voting common stock in the event of an underwritten
public offering.
 
TRANSACTIONS WITH CAROLINA AGRI-SYSTEMS, INC. AND FARMPRO, INC.
 
  In March 1993, certain members of the Sloan family acquired Carolina Agri-
Systems, Inc. ("CASI"), a North Carolina corporation that sold various
products to swine contractors and growers. Larry Sloan owns 50% of the capital
stock of CASI, while Craig Sloan, Jim Sloan and Tom Sloan each own
approximately 16.7% of the capital stock of CASI. In 1995, CASI ceased
distribution operations and the Company wrote-off a $3.4 million receivable
from CASI. Prior to the consummation of the Offering the Company leased two
facilities that were owned by CASI. The first lease (the "Mt. Olive Lease")
was for a facility located in Mt. Olive, North Carolina (the "Mt. Olive
Facility"), which the Company uses for the assembly of hatchery equipment. The
Company made payments to CASI under the Mt. Olive Lease of $138,600 during the
nine months ended September 30, 1997, and of $184,800 during 1996. The other
lease of property owned by CASI (the "Warsaw Lease") was for property located
in Warsaw, North Carolina (the "Warsaw Facility"), which the Company uses as a
sales office and warehouse facility for the sale of swine equipment. The
Company made payments to CASI under the Warsaw Lease of $14,400 during the
nine months ended September 30, 1997, and of $19,200 during 1996. On November
5, 1997, and November 10, 1997, the Company purchased the Mt. Olive Facility
and the Warsaw Facility from CASI for $1,348,203 and $183,928, respectively.
The Company also has made sales in the ordinary course of business of swine
and poultry equipment to CASI. Sales by the Company to CASI were approximately
$0.1 million, $6.0 million and $7.9 million for 1996, 1995 and 1994,
respectively.

  FarmPRO, Inc. ("FarmPRO"), a Pennsylvania corporation that sells swine
equipment, is a significant customer of the Company. FarmPRO, formerly a
wholly owned subsidiary of CASI, was sold by CASI to certain management
members of FarmPRO at the end of 1995. Concurrently with such sale, the
Company and FarmPRO entered into a long-term supply agreement pursuant to
which FarmPRO agreed to purchase 90% of its equipment requirements from the
Company. On November 28, 1997, the Company became a guarantor of FarmPRO's
$5.1 million bank credit facility. Sales by the Company to FarmPRO were
approximately $12.2 million for the nine months ended September 30, 1997, and
$12.8 million, $8.9 million and $5.3 million for 1996, 1995 and 1994,
respectively.
 
OTHER RELATED PARTY TRANSACTIONS
 
  The Company makes sales in the ordinary course of business to Sloan
Implement Company, Inc., a supplier of agricultural equipment that is owned by
certain family members of Craig Sloan. Such transactions generally consist of
sales of grain equipment and amounted to $163,987 for the nine months ended
September 30, 1997, and $129,009, $315,938 and $580,855 for 1996, 1995 and
1994, respectively. In June 1996, Sloan Implement Company, Inc. repaid a note
to the Company in the amount of $1.8 million that was incurred in connection
with certain corporate restructuring activities between the two previously
affiliated entities.
  The Company has made payments to Sloan Transport, Inc., a company formerly
owned by Craig Sloan and certain other Sloan family members, for the use of a
private plane. Such payments were in the amounts of $76,854, $152,880 and
$220,040 for the years 1996, 1995 and 1994, respectively. In 1996, Sloan
Transport Inc. sold all of its assets and was dissolved.
  From time to time the Company extends demand loans to its officers and
directors for the payment of taxes incurred as a result of the Company's
Subchapter "S" status. The annual interest rate on such loans is based on the
prime rate, and has fluctuated between 8.75% and 8.25% during the last three
years. The amount outstanding under such loans for Craig Sloan, Jorge Andrade,
John W. Funk and Howard G. Buffett at September 30, 1997 was $590,300,
$256,395, $193,950 and $87,057, respectively, and the largest amount
outstanding for each individual during 1996 was $518,745, $29,431, $23,423 and
$9,979, respectively. The Company also extended similar loans to Larry Sloan,
Tom Sloan and Jim Sloan, which were repaid in connection with the Redemption.
The largest amounts outstanding under such loans during 1996 were $505,255,
$65,916 and $348,081, during 1995 were $579,058, $43,485 and $418,148, and
during 1994 were $541,132, $40,800 and $278,565, for Larry Sloan, Tom Sloan
and Jim Sloan, respectively. During 1995 and 1994, Craig Sloan advanced loans
to the Company for general corporate purposes. These loans, which bore
interest at the prime rate, were repaid in full during 1996. The largest
amount outstanding under such notes during 1995 and 1994 was $393,803 and
$350,409, respectively.

                    DESCRIPTION OF THE NEW CREDIT AGREEMENT
 
  Concurrently with the consummation of the Offering, the Company entered into
an Amended and Restated Credit Agreement (the "New Credit Agreement") with the
Bank, which amended the Bank Credit Facility. The New Credit Agreement
provides for a revolving credit and letter of credit facility of $40,000,000
terminating in November 2000. The New Credit Agreement bears interest at a
floating rate per annum equal to (at the Company's option): (i) 0.55% to 1.45%
over LIBOR based on the Company's total debt to EBITDA ratio or (ii) the
Bank's prime rate as in effect from time to time. The New Credit Agreement is
available for working capital and general corporate purposes. The Company is
required under the New Credit Agreement to pay the Bank a facility fee on a
quarterly basis. The obligations of the Company under the New Credit Agreement
are secured by a security interest in substantially all of the assets and
properties of the Company.
 
  The New Credit Agreement contains a number of covenants that, among other
things, restricts the ability of the Company to dispose of assets, incur
additional indebtedness, pay dividends or make distributions, create liens on
assets, enter into sale and leaseback transactions, make investments, loans or
advances, make acquisitions, engage in mergers or consolidations, issue
capital stock and form subsidiaries and otherwise restrict certain corporate
activities. In addition, the Company is required to comply with specified
financial ratios and tests.
 
  The New Credit Agreement contains various events of default, including
defaults relating to payments, breaches of representations, warranties and
covenants, certain events of bankruptcy and insolvency, defaults on certain
other indebtedness, certain liens and encumbrances on assets, certain events
terminating employee benefit plans and certain changes of control of the
Company.

                         DESCRIPTION OF THE NEW NOTES
 
  The Old Notes were issued and the New Notes will be issued under an
Indenture dated as of November 1, 1997 (the "Indenture") between the Company
and LaSalle National Bank, as trustee (the "Trustee"), in a private
transaction that is not subject to the registration requirements of the
Securities Act. For purposes of this summary, references to the "Company" mean
only The GSI Group, Inc. and not any of its subsidiaries. References to the
Notes include the New Notes and the Old Notes unless the context otherwise
requires.
 
  Upon the effectiveness of the Registration Statement of which this
Prospectus forms a part, the Indenture will be subject to and governed by the
Trust Indenture Act. The following summaries of the material provisions of the
Indenture do not purport to be complete, and where reference is made to
particular provisions of the Indenture, such provisions, including the
definitions of certain terms, are qualified in their entirety by reference to
all of the provisions of the Indenture and those terms made a part of the
Indenture by reference to the Trust Indenture Act. A copy of the Indenture is
filed as an exhibit to the Registration Statement of which this Prospectus
forms a part, and is incorporated by reference herein. For definitions of
certain capitalized terms used in the following summary, see "--Certain
Definitions" or "Exchange Offer; Registration Rights."
 
GENERAL
 
  The New Notes will be unsecured senior subordinated obligations of the
Company limited to $100,000,000 aggregate principal amount. The New Notes will
be issued solely in exchange for an equal principal amount of outstanding Old
Notes pursuant to the Exchange Offer. The form and terms of the New Notes will
be identical in all material respects to the form and terms of the Old Notes,
except that (i) the New Notes have been registered under the Securities Act
and, therefore, will not bear legends restricting the transfer thereof, (ii)
holders of New Notes will not be entitled to any Additional Interest thereon
pursuant to certain circumstances under the Registration Rights Agreement and
(iii) holders of New Notes will no longer be entitled to certain other rights
under the Registration Rights Agreement. The New Notes will be issued only in
fully registered form without coupons, in denominations of $1,000 and integral
multiples thereof. Principal of, premium, if any, and interest on the Notes
are payable, and the Notes are exchangeable and transferable, at the office or
agency of the Company in the City of New York maintained for such purposes
(which initially will be the corporate trust office of the Trustee). See
"Book-Entry, Delivery and Form." No service charge will be made for any
registration of transfer, exchange or redemption of the Notes, except in
certain circumstances for any tax or other governmental charge that may be
imposed in connection therewith.
 
  DMC has fully and unconditionally guaranteed payment of the Notes on an
unsecured senior subordinated basis. See "--Note Guarantees."
 
MATURITY, INTEREST AND PRINCIPAL
 
  The Notes will mature on November 1, 2007. Interest on the Notes will accrue
at the rate of 10 1/4% per annum and will be payable semi-annually in arrears
on each May 1 and November 1, commencing May 1, 1998, to the holders of record
of Notes at the close of business on the April 15 and October 15,
respectively, immediately preceding such interest payment date. Interest on
the Notes will accrue from the most recent date to which interest has been
paid or, if no interest has been paid, from the Issue Date. Interest will be
computed on the basis of a 360-day year of twelve 30-day months.

OPTIONAL REDEMPTION
 
  Optional Redemption. The Notes will be redeemable at the option of the
Company, in whole or in part, at any time on or after November 1, 2002, at the
redemption prices (expressed as percentages of principal amount) set forth
below, plus accrued and unpaid interest thereon, if any, to the date of
redemption, if redeemed during the 12-month period beginning on November 1 of
the years indicated below:

</TABLE>
 
  Optional Redemption upon Equity Offering. On or prior to November 1, 2000,
the Company may, at its option, use the net proceeds of an Equity Offering to
redeem up to 35% of the originally issued aggregate principal amount of the
Notes, at a redemption price in cash equal to 110.25% of the principal amount
thereof, plus accrued and unpaid interest thereon, if any, to the date of
redemption; provided, however, that not less than $65.0 million in aggregate
principal amount of Notes is outstanding following such redemption. Notice of
any such redemption must be given not later than 60 days after the
consummation of the Equity Offering.
 
  As used in the preceding paragraph, an "Equity Offering" means any public or
private sale of equity securities (other than Redeemable Capital Stock) of the
Company; provided, however, that the proceeds (net of any underwriting
discounts or commissions) to the Company from any such private sale of equity
securities shall be at least $20.0 million.
 
  Selection and Notice. In the event that less than all of the Notes are to be
redeemed at any time, selection of Notes for redemption shall be made by the
Trustee in compliance with the requirements of the principal national
securities exchange, if any, on which the Notes are listed or, if the Notes
are not listed on a national securities exchange, on a pro rata basis, by lot
or by such other method as the Trustee deems fair and appropriate; provided,
however, that no Notes of a principal amount of $1,000 or less shall be
redeemed in part; provided, further, however, that any such redemption made
with the net proceeds of an Equity Offering shall be made on a pro rata basis
or on as nearly a pro rata basis as practicable (subject to the procedures of
DTC). Notice of redemption will be mailed by first class mail at least 30 but
not more than 60 days before the redemption date to each holder of Notes to be
redeemed at its registered address. If any Note is to be redeemed in part
only, the notice of redemption that relates to such Note will state the
portion of the principal amount thereof to be redeemed. A New Note in a
principal amount equal to the unredeemed portion thereof will be issued in the
name of the holder thereof upon cancellation of the original Note. On and
after the redemption date, interest will cease to accrue on Notes or portions
thereof called for redemption so long as the Company has deposited with the
paying agent for the Notes funds in satisfaction of the applicable redemption
price pursuant to the Indenture.
 
CHANGE OF CONTROL
 
  The Indenture provides that, following the occurrence of a Change of Control
(the date of such occurrence being the "Change of Control Date"), the Company
will be obligated, not more than 40 or less than 20 business days after the
Change of Control Date, to make an offer to purchase (a "Change of Control
Offer") all of the then outstanding Notes at a purchase price (the "Change of
Control Purchase Price") in cash equal to 101% of the principal amount
thereof, plus accrued and unpaid interest thereon, if any, to the purchase
date. The Company will be required to purchase all Notes properly tendered
into the Change of Control Offer and not withdrawn.
 
  In order to effect such Change of Control Offer, the Company will, not later
than the 40th business day after the Change of Control Date, be obligated to
mail to each holder of Notes notice of the Change of Control Offer, which
notice will govern the terms of the Change of Control Offer and will state,
among other things, the procedures that holders must follow to accept the
Change of Control Offer. The Change of Control Offer will be required to be
kept open for a period of at least 20 business days.
 
                                      66
<PAGE>
 
  If a Change of Control Offer is made, there can be no assurance that the
Company will have available funds sufficient to pay the purchase price for all
of the Notes that might be tendered by holders of Notes seeking to accept the
Change of Control Offer. If the Company fails to repurchase all of the Notes
tendered for purchase, such failure will constitute an Event of Default under
the Indenture. See "--Events of Default" below.
 
  The Company shall comply, to the extent applicable, with the requirements of
Section 14(e) of the Exchange Act, and any other applicable securities laws or
regulations and any applicable requirements of any securities exchange on
which the Notes are listed, in connection with the repurchase of Notes
pursuant to a Change of Control Offer, and any violation of the provisions of
the Indenture relating to such Change of Control Offer occurring as a result
of such compliance shall not be deemed a Default.
 
SUBORDINATION
 
  The payment of the principal of, premium, if any, and interest on the Notes
will be subordinated in right of payment, as described below, to the prior
payment in full in cash or Cash Equivalents of all Senior Indebtedness.
 
  The Indenture provides that in the event of any insolvency or bankruptcy
case or proceeding, or any receivership, liquidation, reorganization or other
similar case or proceeding in connection therewith, relating to the Company,
or any liquidation, dissolution or other winding-up of the Company, whether
voluntary or involuntary, or any assignment for the benefit of creditors or
other marshaling of assets or liabilities of the Company, all Senior
Indebtedness must be paid in full before any payment or distribution
(excluding any payment or distribution of certain permitted equity or
subordinated securities) is made on account of the principal of, premium, if
any, or interest on the Notes.
 
  During the continuance of any default in the payment of any Designated
Senior Indebtedness pursuant to which the maturity thereof may immediately be
accelerated beyond any applicable grace period and after receipt by the
Trustee from representatives of holders of such Designated Senior Indebtedness
of written notice of such default, no payment or distribution of any assets of
the Company of any kind or character (excluding any payment or distribution of
certain permitted equity or subordinated securities) shall be made on account
of the principal of, premium, if any, or interest on, or the purchase,
redemption or other acquisition of, the Notes unless and until such default
has been cured or waived or has ceased to exist or such Designated Senior
Indebtedness shall have been discharged or paid in full.
 
  During the continuance of any non-payment default with respect to any
Designated Senior Indebtedness pursuant to which the maturity thereof may
immediately be accelerated (a "Non-payment Default") and after the receipt by
the Trustee from the representatives of holders of such Designated Senior
Indebtedness of a written notice of such Non-payment Default, no payment or
distribution of any assets of the Company of any kind or character (excluding
any payment or distribution of certain permitted equity or subordinated
securities) may be made by the Company on account of the principal of,
premium, if any, or interest on, or the purchase, redemption or other
acquisition of, the Notes for the period specified below (the "Payment
Blockage Period").
 
  The Payment Blockage Period will commence upon the receipt of notice of a
Non-payment Default by the Trustee from the representatives of holders of
Designated Senior Indebtedness and will end on the earlier to occur of the
following events: (i) 179 days shall have elapsed since the receipt of such
notice of a Non-payment Default (provided that such Designated Senior
Indebtedness shall not theretofore have been accelerated), (ii) such default
is cured or waived or ceases to exist or such Designated Senior Indebtedness
is discharged or (iii) such Payment Blockage Period shall have been terminated
by written notice to the Company or the Trustee from the representatives of
holders of Designated Senior Indebtedness initiating such Payment Blockage
Period. After the end of any Payment Blockage Period the Company shall
promptly resume making any and all required payments in respect of the Notes,
including any missed payments. Notwithstanding anything in the subordination
provisions of the Indenture or the Notes to the contrary, (x) in no event
shall a Payment Blockage Period extend beyond 179 days from the date of the
receipt by the Trustee of the notice initiating such Payment Blockage Period,
(y) there shall be a period of at least 186 consecutive days in each 365-day
period when no Payment
 
                                      67
<PAGE>
 
Blockage Period is in effect and (z) not more than one Payment Blockage Period
with respect to the Notes may be commenced within any period of 365
consecutive days. A Non-payment Default with respect to Designated Senior
Indebtedness that existed or was continuing on the date of the commencement of
any Payment Blockage Period with respect to the Designated Senior Indebtedness
initiating such Payment Blockage Period cannot be made the basis for the
commencement of a second Payment Blockage Period, whether or not within a
period of 365 consecutive days, unless such default has been cured or waived
for a period of not less than 90 consecutive days and subsequently recurs.
 
  If the Company fails to make any payment on the Notes when due or within any
applicable grace period, whether or not on account of the payment blockage
provisions referred to above, such failure would constitute an Event of
Default under the Indenture and would enable the holders of the Notes to
accelerate the maturity thereof. See "--Events of Default."
 
  By reason of such subordination, in the event of liquidation or insolvency,
creditors of the Company who are holders of Senior Indebtedness may recover
more, ratably, than the holders of the Notes and funds which would be
otherwise payable to the holders of the Notes will be paid to the holders of
Senior Indebtedness to the extent necessary to pay the Senior Indebtedness in
full, and the Company may be unable to meet its obligations fully with respect
to the Notes.
 
  As of September 30, 1997, on a pro forma basis after giving effect to the
Offering, the application of the net proceeds therefrom and the DMC
Acquisition, the Company would have had outstanding $6.9 million of Senior
Indebtedness. In addition, subsidiaries of the Company would have had
outstanding $6.0 million of Indebtedness and other obligations to which
holders of Notes would have been effectively structurally subordinated,
because the claims of creditors of such subsidiaries effectively will have
priority with respect to the assets and earnings of such subsidiaries over the
claims of the Company and its creditors, including holders of the Notes. The
Indenture limits, but does not prohibit, the incurrence by the Company of
additional Indebtedness which is senior to the Notes, but prohibits the
incurrence of any Indebtedness contractually subordinated in right of payment
to any other Indebtedness of the Company and senior in right of payment to the
Notes. See "Risk Factors--Subordination."
 
NOTE GUARANTEES
 
  DMC has fully and unconditionally guaranteed the Company's obligations under
the Notes. In addition, if any Domestic Subsidiary of the Company becomes a
Guarantor or obligor in respect of Indebtedness of the Company, the Company's
obligations under the Notes will be guaranteed by such Domestic Subsidiary.
See "--Certain Covenants--Limitation on Guarantees by Restricted
Subsidiaries." Subject to the subordination provisions described above, if the
Company defaults in payment of the principal of, premium, if any, or interest
on the Notes, DMC and each other Guarantor, if any, will be obligated to duly
and punctually pay the same.
 
  The Indebtedness evidenced by each Note Guarantee (including the payment of
principal of, premium, if any, and interest on the Notes) is subordinated on
the same basis to Guarantor Senior Indebtedness (defined with respect to the
Indebtedness of any Guarantor) as the Notes are subordinated to Senior
Indebtedness. See "--Subordination." As of September 30, 1997, on a pro forma
basis, after giving effect to the Offering, the application of the net
proceeds therefrom and the DMC Acquisition, DMC had no outstanding Guarantor
Senior Indebtedness, however DMC had outstanding $6.0 million of Indebtedness
and other obligations to which holders of the Notes would have been
effectively structurally subordinated, because of the reasons described above.
 
CERTAIN COVENANTS
 
  The Indenture contains the following covenants, among others:
 
  Limitation on Indebtedness. The Company shall not, and shall not cause or
permit any of the Restricted Subsidiaries to, directly or indirectly, create,
incur, assume, issue, guarantee or in any manner become liable for or with
respect to, contingently or otherwise (in each case, to "incur"), the payment
of any Indebtedness (including any Acquired Indebtedness); provided, however,
that (i) the Company and any Guarantor may incur
 
                                      68
<PAGE>
 
Indebtedness (including Acquired Indebtedness) and (ii) a Restricted
Subsidiary may incur Acquired Indebtedness, in each case if immediately after
giving pro forma effect thereto, the Consolidated Fixed Charge Coverage Ratio
of the Company and its Restricted Subsidiaries is at least equal to 2.0:1.0.
 
  Notwithstanding the foregoing, the Company and, to the extent specifically
set forth below, the Restricted Subsidiaries may incur each and all of the
following (collectively, "Permitted Indebtedness"):
 
    (i) Indebtedness of the Company or any Guarantor under the New Credit
  Agreement in an aggregate principal amount at any time outstanding not to
  exceed the greater of (x) $50.0 million and (y) the sum of 85% of the
  consolidated book value of the net accounts receivable and 65% of the
  consolidated book value of the inventory of the Company and its Restricted
  Subsidiaries, in each case determined in accordance with GAAP;
 
    (ii) Indebtedness under the Indenture, the Notes and the Note Guarantees;
 
    (iii) Indebtedness of the Company or any Restricted Subsidiary not
  otherwise referred to in this paragraph that is outstanding on the Issue
  Date, except Indebtedness repaid with the proceeds of the issuance of the
  Notes as described under "Use of Proceeds" (which is permitted hereunder);
 
    (iv) Indebtedness of the Company or any Restricted Subsidiary in respect
  of bid, payment or performance bonds, bankers' acceptances, letters of
  credit of the Company or any Restricted Subsidiary and surety bonds
  provided by the Company or any Restricted Subsidiary in the ordinary course
  of business;
 
    (v) Indebtedness of any Restricted Subsidiary owed to and held by the
  Company or any Restricted Subsidiary, and Indebtedness of the Company owed
  to and held by any other Restricted Subsidiary which is unsecured and
  subordinated in right of payment to the payment and performance of the
  Company's obligations under the Indenture and the Notes;
 
    (vi) any guarantees of Indebtedness by a Restricted Subsidiary incurred
  in compliance with the covenant described under "--Limitations on

  Limitation on Restricted Payments. The Company shall not, and shall not
cause or permit any of the Restricted Subsidiaries, directly or indirectly,
to:
 
    (i) declare or pay any dividend or make any other distribution or payment
  on or in respect of Capital Stock of the Company or any Restricted
  Subsidiary or any payment made to the direct or indirect holders (in their
  capacities as such) of Capital Stock of the Company or any Restricted

  Capital Stock of the Company (other than Redeemable Capital Stock) or in
  rights to purchase Capital Stock of the Company (other than Redeemable
  Capital Stock)); or
 
    (ii) purchase, redeem, defease or otherwise acquire or retire for value
  any Capital Stock of the Company or any Restricted Subsidiary (other than
  any such Capital Stock owned by the Company or a Restricted Subsidiary); or
 
    (iii) make any principal payment on, or purchase, defease, repurchase,
  redeem or otherwise acquire or retire for value, prior to any scheduled
  maturity, scheduled repayment, scheduled sinking fund payment or other
  Stated Maturity, any Subordinated Indebtedness (other than any Subordinated
  Indebtedness owed to and held by a Restricted Subsidiary); or
 
    (iv) make any Investment (other than a Permitted Investment) in any
  Person (such payments or Investments described in clauses (i), (ii), (iii)
  and (iv) are collectively referred to as "Restricted Payments"), unless, at
  the time of and after giving effect to the proposed Restricted Payment (the
  amount of any such Restricted Payment, if other than in cash, being the
  Fair Market Value of the asset(s) proposed to be transferred by the Company
  or such Restricted Subsidiary, as the case may be, pursuant to such
  Restricted Payment):
 
      (A) no Default shall have occurred and be continuing;
 
      (B) the Company could incur $1.00 of additional Indebtedness by
    virtue of the Consolidated Fixed Charge Coverage Ratio set forth in the
    first paragraph of the "Limitation on Indebtedness" covenant described
    above; and
 
      (C) the aggregate amount of all Restricted Payments declared or made
    (and not repaid or reimbursed) from and after the Issue Date would not
    exceed the sum of (1) 50% of cumulative Consolidated Net Income of the

                                      70
<PAGE>
 
    beginning on the first day of the fiscal quarter that includes the
    Issue Date and ending on the last day of the fiscal quarter of the
    Company immediately preceding the date of such proposed Restricted
    Payment for which consolidated financial information of the Company is
    internally available (or, if such cumulative Consolidated Net Income of
    the Company for such period shall be a deficit, minus 100% of such
    deficit), plus (2) the aggregate net cash proceeds received by the
    Company either (x) as capital contributions in the form of common
    equity to the Company after the Issue Date or (y) from the issuance or
    sale of Capital Stock (excluding Redeemable Capital Stock and Capital
    Stock to the extent the proceeds from the sale thereof are used to
    redeem Notes but including Capital Stock issued upon the conversion of
    convertible Indebtedness, in exchange for outstanding Indebtedness or
    from the exercise of options, warrants or rights to purchase Capital
    Stock (other than Redeemable Capital Stock)) of the Company to any
    Person (other than to a Restricted Subsidiary of the Company) after the
    Issue Date (excluding the net cash proceeds from any issuance and sale
    of Capital Stock financed using funds borrowed from the Company or any
    Restricted Subsidiary until and to the extent such borrowing is
    repaid), plus (3) in the case of the disposition or repayment of any
    Investment constituting a Restricted Payment made after the Issue Date,
    an amount equal to the lesser of the return of capital with respect to
    such Investment and the initial amount of such Investment which was
    treated as a Restricted Payment, in either case, less the cost of the
    disposition of such Investment.
 
  For purposes of the preceding clause (C)(2), upon the issuance of Capital
Stock either from the conversion of convertible Indebtedness or exchange for
outstanding Indebtedness or upon the exercise of options, warrants or rights,
the amount counted as net cash proceeds received will be the cash amount
received by the Company at the original issuance of the Indebtedness that is
so converted or exchanged or from the issuance of options, warrants or rights,
as the case may be, plus the incremental amount of cash received by the
Company, if any, upon the conversion, exchange or exercise thereof.
 
  None of the foregoing provisions of this covenant will prohibit:
 
    (i) the payment of any dividend within 60 days after the date of its
  declaration, if at the date of declaration such payment would be permitted
  by the provisions of the Indenture;
 
    (ii) so long as no Default shall have occurred and be continuing or would
  occur upon the consummation thereof, the redemption, repurchase or other
  acquisition or retirement of any shares of any class of Capital Stock of
  the Company in exchange for, or out of the net cash proceeds of, a
  substantially concurrent issue and sale of other shares of Capital Stock
  (other than Redeemable Capital Stock) of the Company to any Person (other
  than to a Restricted Subsidiary); provided, however, that any such net
  proceeds and the value of any Capital Stock issued in exchange for such
  retired Capital Stock are excluded from clause (C)(2) of the preceding
  paragraph;
 
    (iii) so long as no Default shall have occurred and be continuing or
  would occur upon the consummation thereof, any redemption, repurchase or
  other acquisition or retirement of Subordinated Indebtedness made by
  exchange for, or out of the net cash proceeds of, a substantially
  concurrent issue and sale of (A) Capital Stock (other than Redeemable
  Capital Stock) of the Company to any Person (other than to a Restricted
  Subsidiary); provided, however, that any such net cash proceeds and the
  value of any Capital Stock issued in exchange for Subordinated Indebtedness
  are excluded from clause (C)(2) of the preceding paragraph; or (B)
  Indebtedness of the Company or any Restricted Subsidiary so long as such
  Indebtedness (1) is subordinated to Senior Indebtedness and the Notes or
  Guarantor Senior Indebtedness and the Note Guarantees of such Guarantor, as
  the case may be, at least to the same extent as the Subordinated
  Indebtedness so purchased, exchanged, redeemed, repurchased, acquired or
  retired, and (2) has no Stated Maturity earlier than the Stated Maturity
  for the final scheduled principal payment of the Notes;
 
    (iv) Investments constituting Restricted Payments made as a result of the
  receipt of non-cash consideration from any Asset Sale made pursuant to and
  in compliance with the covenant "--Disposition of Proceeds of Asset Sales";
 
    (v) the application of the net proceeds of the Offering on the Issue
  Date, as described under "Use of Proceeds";
 
                                      71
<PAGE>
 
    (vi) so long as no Default shall have occurred and be continuing or would
  occur upon the consummation thereof, the purchase, redemption or other
  acquisition, cancellation or retirement for value of Capital Stock, or
  options, warrants, equity appreciation rights or other rights to purchase
  or acquire Capital Stock, of the Company or any Restricted Subsidiary, or
  similar securities, held by officers or employees or former officers or
  employees of the Company or any Restricted Subsidiary (or their estates or
  beneficiaries under their estates), upon death, disability, retirement or
  termination of employment (collectively "Repurchase Payments"), in an
  amount not to exceed $2.0 million in any single fiscal year, provided that
  to the extent such $2.0 million amount is not utilized in any single fiscal
  year (beginning in the fiscal year containing the Issue Date) such amount
  may be utilized in any future fiscal year;
 
    (vii) so long as no Default shall have occurred and be continuing or
  would occur upon the consummation thereof, in addition to Repurchase
  Payments permitted under clause (vi), Repurchase Payments in an amount not
  to exceed 50% of the sum of (A) Consolidated Net Income plus (B)
  Consolidated Non-cash Charges minus (C) capital expenditures made by the
  Company minus (D) other Repurchase Payments previously made pursuant to
  this clause (vii), in each case determined with respect to the Company and
  its Restricted Subsidiaries on a consolidated basis in accordance with GAAP
  for the four full fiscal quarters immediately preceding the date of any
  such proposed Repurchase Payment for which consolidated financial
  information of the Company is internally available; provided, however, that
  prior to making any such Repurchase Payment under this clause (vii) the
  Company shall have first made an offer to purchase (which offer will be
  required to be kept open for a period of at least 20 business days after
  commencement thereof) to all holders of outstanding Notes up to a maximum
  principal amount (expressed as a multiple of $1,000) of Notes equal to such
  proposed Repurchase Payment (which, if consummated, shall be effected pro
  rata based upon the aggregate principal amount of such Notes tendered by
  each holder), at a purchase price equal to 101% of the principal amount
  thereof, plus accrued and unpaid interest thereon, if any, to the date of
  such purchase; and to the extent the amount of such proposed Repurchase
  Payment exceeds the aggregate amount of Notes tendered by the holders of
  the Notes pursuant to such offer, the Company may make such Repurchase
  Payment;
 
    (viii) loans or advances to officers, directors and employees of the
  Company or any Restricted Subsidiary in an aggregate amount not in excess
  of $2.5 million at any one time outstanding;
 
    (ix) so long as no Default shall have occurred and be continuing or would
  occur upon the consummation thereof, dividends or distributions to
  Permitted Holders who are also officers or directors of the Company, in an

  year of the Company;
 
    (x) payments by the Company in satisfaction of its obligations under the
  Stockholder Agreements from the proceeds of life insurance policies
  received by the Company or any Restricted Subsidiary; or
 
    (xi) so long as the Company remains a Subchapter S corporation under the
  Internal Revenue Code, the payment of dividends or the making of loans or
  advances to the holders of the Company's Capital Stock in an amount equal
  to the Tax Amount (the "Permitted Tax Payments").
 
  In computing the amount of Restricted Payments previously made for purposes
of clause (C) of the preceding paragraph, amounts described under the
immediately preceding clauses (i), (vi) and (vii) shall be included.
 
  Limitation on Transactions with Affiliates. The Company shall not, and shall
not cause or permit any of the Restricted Subsidiaries, directly or
indirectly, to, conduct any business or enter into or suffer to exist any
transaction or series of related transactions with, or for the benefit of, any
of their respective Affiliates (other than a Restricted Subsidiary so long as
no Affiliate of the Company or any beneficial holder of 5% or more of any
class or series of Capital Stock of the Company shall beneficially own any
Capital Stock in such Restricted Subsidiary) or any beneficial holder of 10%
or more of any class of Capital Stock of the Company or any officer or
director of the Company or any Restricted Subsidiary (each, an "Affiliate
Transaction"), unless (i) such Affiliate Transaction is on terms that are no
less favorable to the Company or the Restricted Subsidiary, as the
 
                                      72
<PAGE>
 
case may be, than those which could have been obtained in a comparable
transaction at such time from Persons who do not have such a relationship,
(ii) with respect to any Affiliate Transaction or series of Affiliate
Transactions involving aggregate payments or value equal to or greater than
$2.0 million, the Company shall have delivered an officers' certificate to the
Trustee certifying that such Affiliate Transaction or series of Affiliate
Transactions has been approved by a majority of the Board of Directors of the
Company, including a majority of the disinterested directors, if any, of the
Board of Directors of the Company, and (iii) with respect to any Affiliate
Transaction or series of Affiliate Transactions involving aggregate payments
or value equal to or greater than $5.0 million (or greater than $2.0 million
in the event there are no disinterested directors), the Company shall have
obtained a written opinion from an Independent Financial Advisor stating that
the terms of such Affiliate Transaction or series of Affiliate Transactions
are fair, from a financial point of view, to the Company or the Restricted
Subsidiary involved, as the case may be.
 
  Notwithstanding the foregoing, the restrictions set forth in this covenant
shall not apply to (i) transactions with or among the Company and the
Restricted Subsidiaries; (ii) directors' fees, indemnification and similar
arrangements, consulting fees, employee salaries, bonuses or employment
agreements, compensation or employee benefit arrangements and incentive
arrangements with any officer, director or employee of the Company or any
Restricted Subsidiary entered into in the ordinary course of business
(including customary benefits thereunder) and payments under any
indemnification arrangements permitted by applicable law; (iii) the issue and
sale by the Company to its stockholders of Capital Stock (other than
Redeemable Capital Stock); (iv) any dividends made in compliance with the
provisions described under "--Limitation on Restricted Payments" above; (v)
loans and advances to officers, directors and employees of the Company or any
Restricted Subsidiary for travel, entertainment, moving and other relocation

Restricted Subsidiary in an aggregate amount not in excess of $2.5 million in
any fiscal year; and (vi) the incurrence of intercompany Indebtedness
permitted pursuant to clause (v) of the second paragraph of "--Limitation on
Indebtedness" above.
 
  Disposition of Proceeds of Asset Sales. The Company shall not, and shall not
cause or permit any Restricted Subsidiary, directly or indirectly, to, make
any Asset Sale, unless (i) the Company or such Restricted Subsidiary, as the
case may be, receives consideration at the time of such Asset Sale at least
equal to the Fair Market Value of the assets sold or otherwise disposed of and
(ii) at least 75% of such consideration consists of (A) cash or Cash
Equivalents, (B) properties and capital assets to be used in the same line of
business being conducted by the Company or any Restricted Subsidiary at such
time or (C) Capital Stock in any Person which thereby becomes a Restricted
Subsidiary whose assets consist primarily of properties and capital assets
used in the same line of business being conducted by the Company or any
Restricted Subsidiary at such time. The amount of any (i) Indebtedness (other
than any Subordinated Indebtedness) of the Company or any Restricted
Subsidiary actually assumed by the transferee in such Asset Sale and from
which the Company and the Restricted Subsidiaries are fully released and (ii)
notes or other similar obligations received by the Company or the Restricted
Subsidiaries from such transferee that are immediately converted, sold or
exchanged (or are converted, sold or exchanged within thirty days of the
related Asset Sale) by the Company or the Restricted Subsidiaries into cash,
in an amount equal to the net cash proceeds realized upon such conversion,
sale or exchange, shall be deemed to be cash for purposes of determining the
percentage of cash or Cash Equivalent consideration received by the Company or
the Restricted Subsidiaries.
 
  The Company or such Restricted Subsidiary, as the case may be, may (i) apply
the Net Cash Proceeds of any Asset Sale within 365 days of receipt thereof to
permanently repay Senior Indebtedness or Indebtedness (for purposes of this
clause, a repayment of any amount owing under a revolving credit facility
shall be deemed a permanent repayment to the extent the amount represented by
such repayment is not drawn upon by the Company for a period of six months
after such repayment) of any Restricted Subsidiary that is not subordinated in
right of payment to any Indebtedness of such Restricted Subsidiary, provided,
however, that no such repayment shall affect the amount permitted under clause
(i) of the second paragraph of the covenant "--Limitation on Indebtedness," or
(ii) commit in writing within 365 days after the receipt thereof to acquire,
construct or improve
 
                                      73
<PAGE>
 
properties and capital assets to be used in the same line of business as being
conducted by the Company or any Restricted Subsidiary at such time and so
apply such Net Cash Proceeds within 365 days after the receipt thereof.
 
  To the extent all or part of the Net Cash Proceeds of any Asset Sale are not
applied (or, in the case of clause (ii) above, committed to be so applied in
writing) within 365 days of such Asset Sale as described in clause (i) or (ii)
of the immediately preceding paragraph (such Net Cash Proceeds, the
"Unutilized Net Cash Proceeds"), the Company shall, within 20 business days
after such 365th day, make an offer to purchase (the "Asset Sale Offer") to
all holders of outstanding Notes up to a maximum principal amount (expressed
as a multiple of $1,000) of Notes equal to such Unutilized Net Cash Proceeds,
at a purchase price in cash equal to 100% of the principal amount thereof,
plus accrued and unpaid interest thereon, if any, to the date of such
purchase; provided, however, that the Asset Sale Offer shall not be required
to be made until there are aggregate Unutilized Net Cash Proceeds equal to or
in excess of $7.5 million, at which time the entire amount of such Unutilized
Net Cash Proceeds, and not just the amount in excess of $7.5 million, shall be
applied as required pursuant to this paragraph. An Asset Sale Offer will be
required to be kept open for a period of at least 20 business days after
commencement thereof.
 
  With respect to any Asset Sale Offer effected pursuant to this covenant, to
the extent the aggregate principal amount of Notes tendered pursuant to such
Asset Sale Offer exceeds the Unutilized Net Cash Proceeds to be applied to the
repurchase thereof, such Notes shall be purchased pro rata based on the
aggregate principal amount of such Notes tendered by each holder. To the
extent the Unutilized Net Cash Proceeds exceed the aggregate amount of Notes
tendered by the holders of the Notes pursuant to such Asset Sale Offer, the
Company may retain and utilize any portion of the Unutilized Net Cash Proceeds
not applied to repurchase the Notes for any purpose consistent with the other
terms of the Indenture.
 
  The Company shall comply, to the extent applicable, with the requirements of
Section 14(e) of the Exchange Act, and any other applicable securities laws or
regulations and any applicable requirements of any securities exchange on
which the Notes are listed, and any violation of the provisions of the
Indenture relating to such Asset Sale Offer occurring as a result of such
compliance shall not be deemed a Default.
 
  Limitation on Liens. The Company shall not, and shall not cause or permit
any Restricted Subsidiary to, create, incur, assume or suffer to exist any
Lien of any kind, upon any of its property or assets, whether now owned or
acquired after the Issue Date, or any proceeds therefrom, which secure either
(i) Subordinated Indebtedness unless the Notes, in the case of the Company,
and the Note Guarantees, if any, are secured by a Lien on such property,
assets or proceeds senior in priority to the Liens securing such Subordinated
Indebtedness or (ii) Pari Passu Indebtedness unless the Notes, in the case of
the Company, and the Note Guarantees, are equally and ratably secured with the
Liens securing such Pari Passu Indebtedness.
 
  Limitation on Other Senior Subordinated Indebtedness. Neither the Company
nor any Guarantor shall create, incur, assume, guarantee or in any other
manner become liable with respect to any Indebtedness (other than the Notes
and the Note Guarantees) subordinate in right of payment to any Indebtedness
of the Company or of such Guarantor, as the case may be, unless such
Indebtedness is either (i) pari passu in right of payment with the Notes or
such Note Guarantee, as the case may be, or (ii) subordinate in right of
payment to the Notes or such Note Guarantee, as the case may be, in the same
manner and at least to the same extent as the Notes are subordinated to Senior
Indebtedness or as such Note Guarantee is subordinated to Guarantor Senior
Indebtedness, as the case may be.
 
  Limitation on Guarantees by Restricted Subsidiaries. The Company shall not
cause or permit any of the Domestic Subsidiaries, directly or indirectly, to
guarantee the payment of any Indebtedness of the Company or any Restricted
Subsidiary unless such Domestic Subsidiary (A) is a Guarantor or (B)
simultaneously executes and delivers a supplemental indenture to the Indenture
pursuant to which it will become a Guarantor under the Indenture.
Notwithstanding the foregoing, any Note Guarantee by a Restricted Subsidiary
shall be automatically and unconditionally released and discharged upon any
sale, exchange or transfer, to any Person not an Affiliate of the Company, of
all of the Capital Stock of such Restricted Subsidiary, or all or
substantially all the assets of
 
                                      74
<PAGE>
 
such Restricted Subsidiary, pursuant to a transaction which is in compliance
with the Indenture. The Company may, at any time, cause a Restricted
Subsidiary to become a Guarantor by executing and delivering a supplemental
indenture providing for the guarantee of payment of the Notes by such
Restricted Subsidiary on the basis provided in the Indenture.
 
  Restrictions on Preferred Stock of Restricted Subsidiaries. The Company
shall not sell, and shall not cause or permit any of the Restricted
Subsidiaries to issue, any Preferred Stock of any Restricted Subsidiary (other
than to the Company or to a Wholly-Owned Restricted Subsidiary) or permit any
Person (other than the Company or a Wholly-Owned Restricted Subsidiary) to own
any Preferred Stock of any Restricted Subsidiary.
 
  Limitation on Dividends and Other Payment Restrictions Affecting Restricted
Subsidiaries. The Company shall not, and shall not cause or permit any
Restricted Subsidiary, directly or indirectly, to create or otherwise cause or
suffer to exist, or enter into any agreement with any Person that would cause
to become effective, any consensual encumbrance or restriction of any kind, on
the ability of any Restricted Subsidiary to (a) pay dividends, in cash or
otherwise, or make any other distribution on or in respect of its Capital
Stock or any other interest or participation in, or measured by, its profits,
to the Company or any other Restricted Subsidiary, (b) pay any Indebtedness
owed to the Company or any other Restricted Subsidiary, (c) make loans or
advances to, or guarantee any Indebtedness or other obligations of, the
Company or any other Restricted Subsidiary or (d) transfer any of its property
or assets to the Company or any other Restricted Subsidiary, except (i) any
encumbrance or restriction existing under the security documentation for the
New Credit Agreement as in effect on the Issue Date relating to assets subject
to a Lien created thereby, and with respect to a Restricted Subsidiary that is
not a Restricted Subsidiary on the Issue Date, existing at the time such
Person becomes a Restricted Subsidiary (but not created in contemplation
thereof); provided, however, that such encumbrances and restrictions are not
applicable to the Company or any Restricted Subsidiary, or the properties or
assets of the Company or any Restricted Subsidiary; (ii) customary non-
assignment provisions in leases entered into in the ordinary course of
business and consistent with past practices; (iii) Purchase Money Indebtedness
for property acquired in the ordinary course of business that only imposes
encumbrances and restrictions on the property so acquired; (iv) any agreement
for the sale or disposition of the Capital Stock or assets of any Restricted
Subsidiary; provided, however, that such encumbrances and restrictions
described in this clause (iv) are only applicable to such Restricted
Subsidiary or assets, as applicable, and any such sale or disposition is made
in compliance with "Disposition of Proceeds of Asset Sales" above to the
extent applicable thereto; and (v) any encumbrance or restriction existing
under any agreement that refinances or replaces the agreements containing the
encumbrance or restrictions in the foregoing clauses (i) through (iv);
provided, however, that the terms and conditions of any such restrictions
permitted under this clause (v) are not materially less favorable to the
holders of the Notes than those under or pursuant to the agreement evidencing
the Indebtedness refinanced.
 
  Limitation on Designations of Unrestricted Subsidiaries. The Company may
designate after the Issue Date any Subsidiary (other than a Guarantor) as an
"Unrestricted Subsidiary" under the Indenture (a "Designation") only if:
 
    (i) no Default shall have occurred and be continuing at the time of or
  after giving effect to such Designation;
 
    (ii) the Company would be permitted to make an Investment at the time of
  Designation (assuming the effectiveness of such Designation) in an amount
  (the "Designation Amount") equal to the Fair Market Value of the Company's
  interest in such Subsidiary on such date; and
 
    (iii) the Company would be permitted under the Indenture to incur $1.00
  of additional Indebtedness (other than Permitted Indebtedness) pursuant to
  the covenant described under "--Limitation on Indebtedness" at the time of
  such Designation (assuming the effectiveness of such Designation).
 
  In the event of any such Designation, the Company shall be deemed to have
made an Investment constituting a Restricted Payment pursuant to the covenant
described under "--Limitation on Restricted Payments" for all purposes of the
Indenture in the Designation Amount.
 
                                      75
<PAGE>
 
  The Company may revoke any Designation of a Subsidiary as an Unrestricted
Subsidiary (a "Revocation") if:
 
    (i) no Default shall have occurred and be continuing at the time of and
  after giving effect to such Revocation; and
 
    (ii) all Liens and Indebtedness of such Unrestricted Subsidiary
  outstanding immediately following such Revocation would, if incurred at
  such time, have been permitted to be incurred for all purposes of the
  Indenture.
 
  All Designations and Revocations must be evidenced by Board Resolutions of
the Company delivered to the Trustee certifying compliance with the foregoing
provisions.
 
  Reporting Requirements. So long as any of the Notes are outstanding, the
Company will file with the Commission, to the extent then permitted by the
Commission, the annual reports, quarterly reports and other documents that the
Company would have been required to file with the Commission pursuant to
Sections 13(a) and 15(d) of the Exchange Act if the Company was subject to
such Sections, and the Company will promptly provide to the Trustee copies of
such reports and documents; provided, however, that if the Company is for any
reason unable to make such filings it will make available, upon request, to
any holder of Notes or prospective purchaser of Notes, the information
specified in Rule 144(A)(d)(4) of the Securities Act.
 
CONSOLIDATION, MERGER, SALE OF ASSETS, ETC.
 
  The Indenture provides that the Company shall not, in any transaction or
series of related transactions, merge or consolidate with or into, or sell,
assign, convey, transfer, lease or otherwise dispose of all or substantially
all of its properties and assets as an entirety to, any Person or Persons, and
that the Company shall not permit any of the Restricted Subsidiaries to enter
into any such transaction or series of related transactions if such
transaction or series of related transactions, in the aggregate, would result
in a sale, assignment, conveyance, transfer, lease or other disposition of all
or substantially all of the properties and assets of the Company and the
Restricted Subsidiaries (determined on a consolidated basis for the Company
and the Restricted Subsidiary), to any Person or Persons, unless at the time
and after giving effect thereto (i) either (A)(1) if the transaction or
transactions is a merger or consolidation involving the Company, the Company
shall be the Surviving Person of such merger or consolidation or (2) if the
transaction or transactions is a merger or consolidation involving a
Restricted Subsidiary, such Restricted Subsidiary shall be the Surviving
Person of such merger or consolidation, or (B)(1) the Surviving Person shall
be a corporation organized and existing under the laws of the United States of
America, any State thereof or the District of Columbia and (2)(x) in the case
of a transaction involving the Company, the Surviving Person shall expressly
assume by a supplemental indenture executed and delivered to the Trustee, in
form satisfactory to the Trustee, all the obligations of the Company under the
Notes and the Indenture and the Registration Rights Agreement, and in each
case, the Indenture and the Registration Rights Agreement shall remain in full
force and effect, or (y) in the case of a transaction involving a Restricted
Subsidiary that is a Guarantor, the Surviving Person shall expressly assume by
a supplemental indenture executed and delivered to the Trustee, inform
satisfactory to the Trustee, all the obligations of such Restricted Subsidiary
under its Note Guarantee and the Indenture and the Registration Rights
Agreement, and in each case, such Indenture and the Registration Rights
Agreement shall remain in full force and effect; (ii) immediately after giving
effect to such transaction or series of related transactions on a pro forma
basis, no Default shall have occurred and be continuing; and (iii) the
Company, or the Surviving Person, as the case may be, immediately after giving
effect to such transaction or series of transactions on a pro forma basis
(including, without limitation, any Indebtedness incurred or anticipated to be
incurred in connection with or in respect of such transaction or series of
transactions), could incur $1.00 of additional Indebtedness (other than
Permitted Indebtedness) under the first paragraph of the "--Limitation on
Indebtedness" covenant described above.
 
  In connection with any consolidation, merger, transfer, lease or other
disposition contemplated hereby, the Company shall deliver, or cause to be
delivered, to the Trustee, in form and substance reasonably satisfactory to
the Trustee, an officers' certificate and an opinion of counsel, each stating
that such consolidation, merger, transfer, lease or other disposition and the
supplemental indenture in respect thereof comply with the
 
                                      76
<PAGE>
 
requirements under the Indenture. In addition, each Guarantor, in the case of
a transaction described in the first paragraph hereunder, unless it is the
other party to the transaction or unless its Note Guarantee will be released
and discharged in accordance with its terms as a result of the transaction,
will be required to confirm, by supplemental indenture, that its Note
Guarantee will continue to apply to the obligations of the Company or the
Surviving Person under the Indenture.
 
  Upon any consolidation or merger of the Company or any Guarantor or any
transfer of all or substantially all of the assets of the Company in
accordance with the foregoing, in which the Company or a Guarantor is not the
Surviving Person, the Surviving Person shall succeed to, and be substituted
for, and may exercise every right and power of, the Company under the
Indenture and the Notes and the Registration Rights Agreement or such
Guarantor under the Indenture, the Note Guarantee of such Guarantor and the
Registration Rights Agreement, as the case may be, with the same effect as if
such successor corporation had been named as the Company or Guarantor, as the
case may be, therein; and thereafter, except in the case of (a) a lease or (b)
any sale, assignment, conveyance, transfer, lease or other disposition to a
Restricted Subsidiary of the Company or such Guarantor, the Company shall be
discharged from all obligations and covenants under the Indenture and the
Notes and such Guarantor shall be discharged from all obligations and
covenants under the Indenture and the Note Guarantee of such Guarantor, as the
case may be.
 
  The Indenture provides that for all purposes of the Indenture and the Notes
(including the provisions of this covenant and the covenants described in "--
Limitation on Indebtedness," "--Limitation on Restricted Payments" and
"Limitation on Liens"), Subsidiaries of any Surviving Person shall, upon such
transaction or series of related transactions, become Restricted Subsidiaries
unless and until designated as Unrestricted Subsidiaries pursuant to and in
accordance with "--Limitation on Designations of Unrestricted Subsidiaries"
and all Indebtedness, and all Liens on property or assets, of the Company and
the Restricted Subsidiaries in existence immediately prior to such transaction
or series of related transactions will be deemed to have been incurred upon
consummation of such transaction or series of related transactions.
 
EVENTS OF DEFAULT
 
  The following will be "Events of Default" under the Indenture:
 
    (i) default in the payment of the principal of or premium, if any, when
  due and payable, on any of the Notes (at its Stated Maturity, upon optional
  redemption, required purchase, scheduled principal payment or otherwise);
  or
 
    (ii) default in the payment of an installment of interest on any of the
  Notes, when due and payable, continued for 30 days or more; or
 
    (iii) the Company or any Guarantor fails to comply with any of its
  obligations described under
  "--Consolidation, Merger, Sale of Assets, Etc.," "--Certain Covenants--
  Change of Control" or
  "--Certain Covenants--Disposition of Proceeds of Asset Sales"; or
 
    (iv) the Company or any Guarantor fails to perform or observe any other
  term, covenant or agreement contained in the Notes, the Note Guarantees or
  the Indenture (other than a default specified in (i), (ii) or (iii) above)
  for a period of 30 days after written notice of such failure requiring the
  Company to remedy the same shall have been given (x) to the Company by the
  Trustee or (y) to the Company and the Trustee by the holders of 25% in
  aggregate principal amount of the Notes then outstanding; or
 
    (v) default or defaults under one or more agreements, indentures or
  instruments under which the Company or any Restricted Subsidiary then has
  outstanding Indebtedness in excess of $7.5 million individually or in the
  aggregate and either (a) such Indebtedness is already due and payable in
  full or (b) such default or defaults results in the acceleration of the
  maturity of such Indebtedness; or
 
    (vi) any Note Guarantee ceases to be in full force and effect or is
  declared null and void or any Guarantor denies that it has any further
  liability under any Note Guarantee, or gives notice to such effect (other
  than by reason of the termination of the Indenture or the release of any
  such Note Guarantee in
 
                                      77
<PAGE>
 
  accordance with "--Certain Covenants--Limitation on Guarantees by
  Restricted Subsidiaries") and such condition shall have continued for a
  period of 30 days after notice to the Company by the Trustee; or
 
    (vii) one or more judgments, orders or decrees of any court or regulatory
  or administrative agency for the payment of money in excess of $7.5 million
  either individually or in the aggregate shall have been rendered against
  the Company or any Restricted Subsidiary or any of their respective
  properties and shall not have been discharged and either (a) any creditor
  shall have commenced an enforcement proceeding upon such judgment, order or
  decree, and such judgment is not being appealed by the Company or (b) there
  shall have been a period of 60 consecutive days during which a stay of
  enforcement of such judgment, order or decree, by reason of a pending
  appeal or otherwise, shall not be in effect; or
 
    (viii) certain events of bankruptcy, insolvency or reorganization with
  respect to the Company or any Material Subsidiary of the Company shall have
  occurred.
 
  If an Event of Default (other than as specified in clause (viii) with
respect to the Company) shall occur and be continuing, the Trustee, by notice
to the Company, or the holders of at least 25% in aggregate principal amount
of the Notes then outstanding, by notice to the Trustee and the Company, may
declare the principal of, premium, if any, and accrued interest on all of the
outstanding Notes due and payable immediately, upon which declaration all such
amounts payable in respect of the Notes will become and be immediately due and
payable; provided, however, that so long as the New Credit Agreement shall be
in force and effect, if an Event of Default shall have occurred and be
continuing (other than an Event of Default under clause (viii) with respect to
the Company), any such acceleration shall not be effective until the earlier
to occur of (x) five business days following delivery of a notice of such
acceleration to the agent under the New Credit Agreement and (y) the
acceleration of any Indebtedness under the New Credit Agreement. If an Event
of Default specified in clause (viii) above with respect to the Company occurs
and is continuing, then the principal of, premium, if any, and accrued
interest on all of the outstanding Notes will ipso facto become and be
immediately due and payable without any declaration or other act on the part
of the Trustee or any holder of Notes.
 
  Notwithstanding the preceding paragraph, in the event of a declaration of
acceleration in respect of the Notes because an Event of Default specified in
clause (v) shall have occurred and be continuing, such declaration of
acceleration will be automatically annulled if the Indebtedness that is the
subject of such Event of Default has been discharged or paid (if permitted by
the terms thereof and the Indenture) or the requisite holders thereof have
rescinded their declaration of acceleration in respect of such Indebtedness,
and written notice of such discharge or rescission, as the case may be, shall
have been given to the Trustee by the Company, within 60 days after such
declaration of acceleration in respect of the Notes and no other Event of
Default has occurred which has not been cured or waived during such 60-day
period.
 
  After a declaration of acceleration, but before a judgment or decree for
payment of the money due has been obtained by the Trustee, the holders of a
majority in aggregate principal amount of the outstanding Notes, by written
notice to the Company and the Trustee, may rescind such declaration if (a) the
Company has paid or deposited with the Trustee a sum sufficient to pay (i) all
sums paid or advanced by the Trustee under the Indenture and the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, (ii) all overdue interest on all Notes, (iii) the principal of
and premium, if any, on any Notes which have become due otherwise than by such
declaration of acceleration and interest thereon at the rate borne by the
Notes and (iv) to the extent that payment of such interest is lawful, interest
upon overdue interest at the rate borne by the Notes; and (b) all Events of
Default, other than the non-payment of principal of, premium, if any, and
interest on the Notes that has become due solely by such declaration of
acceleration, have been cured or waived.
 
  No holder of any of the Notes has any right to institute any proceeding with
respect to the Indenture or any remedy thereunder, unless the holders of at
least 25% in aggregate principal amount of the outstanding Notes have made
written request, and offered reasonable indemnity, to the Trustee to institute
such proceeding as Trustee under the Notes and the Indenture, the Trustee has
failed to institute such proceeding within 15 days after receipt of such
notice and the Trustee, within such 15-day period, has not received directions
inconsistent
 
                                      78
<PAGE>
 
with such written request by holders of a majority in aggregate principal
amount of the outstanding Notes. Such limitations do not apply, however, to a
suit instituted by a holder of a Note for the enforcement of the payment of
the principal of, premium, if any, or interest on such Note on or after the
respective due dates expressed in such Note.
 
  During the existence of an Event of Default, the Trustee is required to
exercise such rights and powers vested in it under the Indenture and use the
same degree of care and skill in its exercise thereof as a prudent Person
would exercise under the circumstances in the conduct of such Person's own
affairs. Subject to the provisions of the Indenture relating to the duties of
the Trustee, in case an Event of Default shall occur and be continuing, the
Trustee under the Indenture is not under any obligation to exercise any of its
rights or powers under the Indenture at the request or direction of any of the
holders unless such holders shall have offered to the Trustee reasonable
security or indemnity. Subject to certain provisions concerning the rights of
the Trustee, the holders of a majority in aggregate principal amount of the
outstanding Notes have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee, or
exercising any trust or power conferred on the Trustee under the Indenture.
 
  The Company is required to furnish to the Trustee annual statements as to
the performance by the Company and any Guarantor of their respective
obligations under the Indenture and as to any default in such performance. The
Company is also required to notify the Trustee within ten business days of any
event which is, or after notice or lapse of time or both would become, an
Event of Default.
 
DEFEASANCE OR COVENANT DEFEASANCE OF INDENTURE
 
  The Company may, at its option and at any time, terminate the obligations of
the Company and any Guarantor with respect to the outstanding Notes
("defeasance"). Such defeasance means that the Company will be deemed to have
paid and discharged the entire Indebtedness represented by the outstanding
Notes, except for (i) the rights of holders of outstanding Notes to receive
payment in respect of the principal of, premium, if any, and interest on such
Notes when such payments are due, (ii) the Company's obligations to issue
temporary Notes, register the transfer or exchange of any Notes, replace
mutilated, destroyed, lost or stolen Notes and maintain an office or agency
for payments in respect of the Notes, (iii) the rights, powers, trusts, duties
and immunities of the Trustee and (iv) the defeasance provisions of the
Indenture. In addition, the Company may, at its option and at any time, elect
to terminate the obligations of the Company and any Guarantor with respect to
certain covenants that are set forth in the Indenture, some of which are
described under "--Certain Covenants" above, and any omission to comply with
such obligations will not constitute a Default or an Event of Default with
respect to the Notes ("covenant defeasance").
 
  In order to exercise either defeasance or covenant defeasance, (i) the
Company must irrevocably deposit with the Trustee, in trust, for the benefit
of the holders of the Notes, cash in United States dollars, U.S. Government
Obligations (as defined in the Indenture), or a combination thereof, in such
amounts as will be sufficient, in the opinion of a nationally recognized firm
of independent public accountants, to pay the principal of, premium, if any,
and interest on the outstanding Notes at maturity; (ii) the Company shall have
delivered to the Trustee an opinion of counsel to the effect that the holders
of the outstanding Notes will not recognize income, gain or loss for federal
income tax purposes as a result of such defeasance or covenant defeasance and
will be subject to federal income tax on the same amounts, in the same manner
and at the same times as would have been the case if such defeasance or
covenant defeasance had not occurred (in the case of defeasance, such opinion
must refer to and be based upon a ruling of the Internal Revenue Service or a
change in applicable federal income tax laws); (iii) no Default shall have
occurred and be continuing on the date of such deposit; (iv) such defeasance
or covenant defeasance shall not cause the Trustee to have a conflicting
interest with respect to any securities of the Company or any Guarantor; (v)
such defeasance or covenant defeasance shall not result in a breach or
violation of, or constitute a default under, any material agreement or
instrument to which the Company or any Guarantor is a party or by which it is
bound; (vi) the Company shall have delivered to the Trustee an opinion of
counsel to the effect that (A) the trust funds will not be subject to any
rights of holders of Senior
 
                                      79
<PAGE>
 
Indebtedness, including, without limitation, those arising under the Indenture
and (B) after the 91st day following the deposit, the trust funds will not be
subject to the effect of any applicable bankruptcy, insolvency, reorganization
or similar laws affecting creditors' rights generally; and (vii) the Company
shall have delivered to the Trustee an officers' certificate and an opinion of
counsel, each stating that all conditions precedent under the Indenture to
either defeasance or covenant defeasance, as the case may be, have been
complied with.
 
SATISFACTION AND DISCHARGE
 
  The Indenture will be discharged and will cease to be of further effect
(except as to surviving rights or registration of transfer or exchange of the
Notes, as expressly provided for in the Indenture) as to all outstanding Notes
when (i) either (a) all the Notes theretofore authenticated and delivered
(except lost, stolen or destroyed Notes which have been replaced or paid and
Notes for whose payment money has theretofore been deposited in trust or
segregated and held in trust by the Company and thereafter repaid to the
Company or discharged from such trust) have been delivered to the Trustee for
cancellation or (b) all Notes not theretofore delivered to the Trustee for
cancellation have become due and payable and the Company or any Guarantor has
irrevocably deposited or caused to be deposited with the Trustee funds in an
amount sufficient to pay and discharge the entire Indebtedness on the Notes
not theretofore delivered to the Trustee for cancellation, for principal of,
premium, if any, and interest on the Notes to the date of deposit together
with irrevocable instructions from the Company directing the Trustee to apply
such funds to the payment thereof at maturity or redemption, as the case may
be; (ii) the Company or any Guarantor has paid all other sums payable under
the Indenture by the Company and any Guarantor; and (iii) the Company and each
Guarantors have delivered to the Trustee an officers' certificate and an
opinion of counsel each stating that all conditions precedent under the
Indenture relating to the satisfaction and discharge of the Indenture have
been complied with.
 
AMENDMENTS AND WAIVERS
 
  From time to time, the Company and any Guarantor, when authorized by
resolutions of their boards of directors, and the Trustee may, without the
consent of the holders of any outstanding Notes, amend, waive or supplement
the Indenture or the Notes for certain specified purposes, including, among
other things, curing ambiguities, defects or inconsistencies, qualifying, or
maintaining the qualification of, the Indenture under the Trust Indenture Act,
or making any change that does not materially adversely affect the legal
rights of any holder; provided, however, that the Company has delivered to the
Trustee an opinion of counsel stating that such change does not materially
adversely affect the legal rights of any holder. Other amendments and
modifications of the Indenture or the Notes may be made by the Company, any
Guarantor and the Trustee with the consent of the holders of not less than a
majority of the aggregate principal amount of the outstanding Notes; provided,
however, that no such modification or amendment may, without the consent of
the holder of each outstanding Note affected thereby, (i) change the maturity
of the principal of or any installment of interest on any such Note or alter
the optional redemption or repurchase provisions of any such Note or the
Indenture in a manner adverse to the holders of the Notes; (ii) reduce the
principal amount (or the premium) of any such Note; (iii) reduce the rate of
or extend the time for payment of interest on any such Note; (iv) change the
place or currency of payment of principal of (or premium) or interest on any
such Note; (v) modify any provisions of the Indenture relating to the waiver
of past defaults (other than to add sections of the Indenture or the Notes
subject thereto) or the right of the holders of Notes to institute suit for
the enforcement of any payment on or with respect to any such Note or any Note
Guarantee in respect thereof or the modification and amendment provisions of
the Indenture and the Notes (other than to add section of the Indenture or the
Notes which may not be amended, supplemented or waived without the consent of
each holder therein affected); (vi) reduce the percentage of the principal
amount of outstanding Notes necessary for amendment to or waiver of compliance
with any provision of the Indenture or the Notes or for waiver of any Default
in respect thereof; (vii) waive a default in the payment of principal of,
interest on, or redemption payment with respect to, the Notes (except a
rescission of acceleration of the Notes by the holders thereof as provided in
the Indenture and a waiver of the payment default that resulted from such
acceleration); (viii) modify the ranking or priority of any Note or the Note
Guarantee in respect thereof of any Guarantor or modify the definition of
Senior Indebtedness or Guarantor Senior Indebtedness or amend or modify
 
                                      80
<PAGE>
 
the subordination provisions of the Indenture in any manner adverse to the
holders of the Notes; or (ix) release any Guarantor from any of its
obligations under its Note Guarantee or the Indenture otherwise than in
accordance with the Indenture.
 
  The holders of a majority in aggregate principal amount of the outstanding
Notes, on behalf of all holders of Notes, may waive compliance by the Company
and any Guarantor with certain restrictive provisions of the Indenture.
Subject to certain rights of the Trustee, as provided in the Indenture, the
holders of a majority in aggregate principal amount of the Notes, on behalf of
all holders of the Notes, may waive any past default under the Indenture
(including any such waiver obtained in connection with a tender offer or
exchange offer for the Notes), except a default in the payment of principal,
premium or interest or a default arising from failure to purchase any Notes
tendered pursuant to an optional redemption or repurchase, or a default in
respect of a provision that under the Indenture cannot be modified or amended
without the consent of the holder of each Note that is affected.

amount of Consolidated Cash Flow Available for Fixed Charges of the Company
for the four full fiscal quarters immediately preceding the date of the
transaction (the "Transaction Date") giving rise to the need to calculate the
Consolidated Fixed Charge Coverage Ratio for which consolidated financial
information of the Company is internally available (such four full fiscal
quarter period being referred to herein as the "Four Quarter Period") to the
aggregate amount of Consolidated Fixed Charges of the Company for such Four
Quarter Period. For purposes of this definition, "Consolidated Cash Flow
Available for Fixed Charges" and "Consolidated Fixed Charges" will be
calculated, without duplication, after giving effect on a pro forma basis for
the period of such calculation to (i) the incurrence of any Indebtedness of
the Company or any of the Restricted Subsidiaries during the period commencing
on the first day of the Four Quarter Period to and including the Transaction
Date (the "Reference Period"), including, without limitation, the incurrence
of the Indebtedness giving rise to the need to make such calculation, as if
such incurrence occurred on the first day of the Reference Period, (ii) an
adjustment to eliminate or include, as applicable, the Consolidated Cash Flow
Available for Fixed Charges and Consolidated Fixed Charges of the Company
directly attributable to assets which are the subject of any Asset Sale or
Asset Acquisition (including, without limitation, any Asset Acquisition giving
rise to the need to make such calculation as a result of the Company or one of
the Restricted Subsidiaries (including any Person who becomes a Restricted
Subsidiary as a result of the Asset Acquisition) incurring, assuming or
otherwise being liable for Acquired Indebtedness) occurring during the
Reference Period, as if such Asset Sale or Asset Acquisition occurred on the
first day of the Reference Period and (iii) the retirement of Indebtedness
during the Reference Period which cannot thereafter be reborrowed occurring as
if retired on the first day of the Reference Period. Furthermore, in
calculating Consolidated Fixed Charges for purposes of determining the
denominator (but not the numerator) of this definition of "Consolidated Fixed
Charge Coverage Ratio," (1) interest on Indebtedness determined on a
fluctuating basis as of the Transaction Date and which will continue to be so
determined thereafter will be deemed to accrue at a fixed rate per annum equal
to the rate of interest on such Indebtedness in effect on the Transaction
Date; (2) if interest on any Indebtedness actually incurred on the Transaction
Date may optionally be determined at an interest rate based upon a factor of a
prime or similar rate, a eurocurrency interbank offered rate, or other rates,
then the interest rate in effect on the Transaction Date shall be deemed to
have been in effect during the Reference Period; and (3) notwithstanding
clause (1) above, interest on Indebtedness determined on a fluctuating basis,
to the extent such interest is covered by agreements relating to Interest Rate
Protection Obligations, will be deemed to accrue at the rate per annum
resulting after giving effect to the operation of such agreements. If the
Company or any Restricted Subsidiaries directly or indirectly guarantees
Indebtedness of a third Person, the above definition will give effect to the
incurrence of such guaranteed Indebtedness as if the Company or any Restricted
Subsidiary had directly incurred or otherwise assumed such guaranteed
Indebtedness.

restricted period" within the meaning of Rule 903 of Regulation S, transfers
of interest in the Offshore Global Old Note were only effected through records

(b) ownership of beneficial interests in the Global New Note will be shown on,
and the transfer of ownership thereof will be effected only through, records
maintained by DTC or its nominee (with respect to interests of Participants
(as defined herein)) and the records of Participants (with respect to
interests of persons other than Participants). Ownership of beneficial
interests in the Global New Note will be limited to persons who have accounts
with DTC ("Participants") or persons who hold interests through Participants.
QIBs may hold their interests in the Global New Note directly through DTC if
they are Participants in such system, or indirectly through organizations
which are Participants in such system.
 
  So long as DTC, or its nominee, is the registered owner or holder of the New
Notes, DTC or such nominee, as the case may be, will be considered the sole
owner and holder of the New Notes represented by such Global New Note for all
purposes under the Indenture. No beneficial owner of an interest in the Global
New Note will be able to transfer such interest except in accordance with
DTC's procedures, in addition to those provided for under the Indenture with
respect to the New Notes.
 
  Payments of the principal of or premium and interest on the Global New Note
will be made to DTC or its nominee, as the case may be, as the registered
owner thereof. None of the Company, the Trustee or any paying agent under the
Indenture will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests in the Global New Note or for maintaining, supervising or reviewing
any records relating to such beneficial ownership interest.
 
  The Company expects that DTC or its nominee, upon receipt of any payment of
the principal of or premium and interest on the Global New Note, will credit
Participants' accounts with payments in amounts proportionate to their
respective beneficial interests in the principal amount of such Global New
Note as shown on the records
 
                                      91
<PAGE>
 
of DTC or its nominee. The Company also expects that payments by Participants
to owners of beneficial interests in the Global New Note held through such
Participants will be governed by standing instructions and customary practice
as is now the case with securities held for the accounts of customers
registered in the names of nominees for such customers. Such payments will be
the responsibility of such Participants.
 
  Transfers between Participants in DTC will be effected in the ordinary way
through DTC's same-day funds system in accordance with DTC rules and will be
settled in federal funds. If a holder requires physical delivery of a
Certificated New Note for any reason, including to sell New Notes to persons
in states that require physical delivery of the New Notes or to pledge such
securities, such holder must transfer its interest in the Global New Note in
accordance with normal procedures of DTC and with the procedures set forth in
the Indenture.
 
  DTC has advised the Company that DTC will take any action permitted to be
taken by a holder of New Notes (including the presentation of New Notes for
exchange as described below) only at the direction of one or more Participants
to whose account the DTC interests in the Global New Note are credited and
only in respect of such portion of the aggregate principal amount of New Notes
as to which such Participant or Participants has or have given such direction.
However, if there is an Event of Default under the Indenture, DTC will
exchange the Global New Note for Certificated New Notes, which it will
distribute to its Participants.
 
  DTC has advised the Company as follows: DTC is a limited purpose trust
company organized under the laws of the State of New York, a member of the
Federal Reserve System, a "clearing corporation" within the meaning of the
Uniform Commercial Code and a "clearing agency" registered pursuant to the
provisions of Section 17A of the Exchange Act. DTC was created to hold
securities for its Participants and facilitate the clearance and settlement of
securities transactions between Participants through electronic book-entry
changes in accounts of its Participants, thereby eliminating the need for
physical movement of certificates. Participants include securities brokers and
dealers, banks, trust companies and clearing corporations and certain other
organizations. Indirect access to the DTC system is available to others such
as banks, brokers, dealers and trust companies that clear through or maintain
a custodial relationship with a Participant, either directly or indirectly
("Indirect Participants").
 
  Although DTC, Euroclear and Cedel are expected to follow the foregoing
procedures in order to facilitate transfers of interest in the Global New
Notes among Participants of DTC, they are under no obligation to perform such
procedures, and such procedures may be discontinued at any time. Neither the
Company nor the Trustee will have any responsibility for the performance by
DTC, Euroclear and Cedel or the Participants or Indirect Participants of their
respective obligations under the rules and procedures governing their
operations.
 
  CERTIFICATED NEW NOTES. Interests in the Global New Note will be
exchangeable or transferable, as the case may be, for Certificated Notes if
(i) DTC notifies the Company that it is unwilling or unable to continue as
depositary for such Global New Note, or DTC ceases to be a "Clearing Agency"
registered under the Exchange Act, and a successor depositary is not appointed
by the Company within 90 days, or (ii) an Event of Default has occurred and is
continuing with respect to such New Notes. Upon the occurrence of any of the
events described in the preceding sentence, the Company will cause the
appropriate Certificated New Notes to be delivered.
 
                              REGISTRATION RIGHTS
 
  Pursuant to the Registration Rights Agreement with the Initial Purchasers,
the Company agreed to file with the Commission the Exchange Offer Registration
Statement of which this Prospectus is a part on an appropriate form under the
Securities Act with respect to an offer to exchange the Old Notes for the New
Notes. Upon the effectiveness of the Exchange Offer Registration Statement,
the Company will offer to the holders of Old Notes who are able to make
certain representations the opportunity to exchange their Old Notes for New
Notes. If (i) the Company is not permitted to file the Exchange Offer
Registration Statement or to consummate the Exchange Offer because the
Exchange Offer is not permitted by applicable law or Commission policy, (ii)
the Exchange Offer is not for any other reason consummated within 180 days
after the Issue Date, (iii) any holder of Old Notes
 
                                      92
<PAGE>
 
notifies the Company within a specified time period that (a) due to a change
in applicable law or Commission policy it is not entitled to participate in
the Exchange Offer, (b) due to a change in applicable law or Commission policy
it may not resell the New Notes acquired by it in the Exchange Offer to the
public without delivering a prospectus and the prospectus contained in the
Exchange Offer Registration Statement is not appropriate or available for such
resales by such holder or (c) it is a broker-dealer and owns Old Notes
acquired directly from the Company or (iv) the holders of a majority of the
Old Notes may not resell the New Notes to be acquired by them in the Exchange
Offer to the public without restriction under the Securities Act and without
restriction under applicable blue sky or state securities laws, the Company
will file with the Commission the Shelf Registration Statement to cover
resales of the Transfer Restricted Notes (as defined herein) by the holders
thereof. The Company will use its best efforts to cause the applicable
registration statement to be declared effective as promptly as possible by the
Commission. For purposes of the foregoing, "Transfer Restricted Notes" means
each Old Note until (i) the date on which such Old Note has been exchanged by
a person other than a broker-dealer for a New Note in the Exchange Offer, (ii)
following the exchange by a broker-dealer in the Exchange Offer of an Old Note
for a New Note, the date on which such New Note is sold to a purchaser who
receives from such broker-dealer on or prior to the date of such sale a copy
of the prospectus contained in the Exchange Offer Registration Statement,
(iii) the date on which such Old Note has been effectively registered under
the Securities Act and disposed of in accordance with the Shelf Registration
Statement, (iv) the date on which such Old Note is distributed to the public
pursuant to Rule 144(k) under the Securities Act (or any similar provision
then in force, but not Rule 144A under the Securities Act), (v) such Old Note
shall have been otherwise transferred by the holder thereof and a New Note not
bearing a legend restricting further transfer shall have been delivered by the
Company and subsequent disposition of such Old Note shall not require
registration or qualification under the Securities Act or any similar state
law then in force or (vi) such Old Note ceases to be outstanding.
 
  Under existing Commission interpretations, the New Notes would, in general,
be freely transferable after the Exchange Offer without further registration
under the Securities Act; provided, that in the case of broker-dealers
participating in the Exchange Offer, a prospectus meeting the requirements of
the Securities Act must be delivered upon resale by such broker-dealers in
connection with resales of the New Notes. The Company has agreed, for period
of 180 days after consummation of the Exchange Offer, to make available a
prospectus meeting the requirements of the Securities Act to any such broker-
dealer for use in connection with any resale of any New Notes acquired in the
Exchange Offer. A broker-dealer who delivers such a prospectus to purchasers
in connection with such resales will be subject to certain of the civil
liability provisions under the Securities Act and will be bound by the
provisions of the Registration Rights Agreement (including certain
indemnification rights and obligations).
 
  Each holder of Old Notes who wishes to exchange such Old Notes for New Notes
in the Exchange Offer will be required to make certain representations,
including representations that: (i) the holder is not an "affiliate" of the
Company as defined in Rule 405 of the Securities Act, (ii) the holder is not a
broker-dealer that acquired Old Notes directly from the Company in order to
resell them pursuant to Rule 144A of the Securities Act or any other available
exemption under the Securities Act, (iii) the holder will acquire the New
Notes in the ordinary course of business and (iv) the holder is not
participating, and does not intend to participate, and has no arrangement or
understanding with any person to participate, in the distribution of the New
Notes.
 
  If the holder is a broker-dealer that will receive New Notes for its own
account in exchange for Old Notes that were acquired as a result of market-
making activities or other trading activities, it will be required to
acknowledge that it will deliver a prospectus in connection with any resale of
such New Notes.
 
  The Company has agreed to pay all expenses incident to the Exchange Offer
and will indemnify the Initial Purchasers against certain liabilities,
including liabilities under the Securities Act.
 
  The Registration Rights Agreement provides that (i) unless the Exchange
Offer would not be permitted by applicable law or Commission policy, the
Company will use its best efforts to file the Exchange Offer Registration
Statement with the Commission on or prior to 90 days after the Issue Date,
(ii) unless the Exchange
 
                                      93
<PAGE>
 
Offer would not be permitted by applicable law or Commission policy, the
Company will use its best efforts to have the Exchange Offer Registration
Statement declared effective by the Commission on or prior to 150 days after
the Issue Date, (iii) unless the Exchange Offer would not be permitted by
applicable law or Commission policy, the Company will use its best efforts to
have the Exchange Offer Registration Statement remain effective until the
closing of the Exchange Offer, (iv) unless the Exchange Offer would not be
permitted by applicable law or Commission policy, the Company will commence
the Exchange Offer and use its best efforts to issue, on or prior to 180 days
after the Issue Date, New Notes in exchange for all Old Notes tendered prior
thereto in the Exchange Offer and (v) if obligated to file the Shelf
Registration Statement, the Company will use its best efforts to file the
Shelf Registration Statement prior to the later of (a) 120 days after the
Issue Date or (b) 30 days after such filing obligation arises and use its best
efforts to cause the Shelf Registration Statement to be declared effective by
the Commission on or prior to 60 days after such obligation arises; provided,
that if the Company has not consummated the Exchange Offer within 180 days of
the Issue Date, then the Company will file the Shelf Registration Statement
with the Commission on or prior to the 181st day after the Issue Date. The
Company shall use its best efforts to keep such Shelf Registration Statement
continuously effective, supplemented and amended until the second anniversary
of the Issue Date or such shorter period that will terminate when all the
Transfer Restricted Notes covered by the Shelf Registration Statement have
been sold pursuant thereto. A holder of Old Notes who intends to sell such Old
Notes pursuant to the Shelf Registration Statement will be required to be
named as a selling securityholder in the related prospectus and to deliver
such prospectus to purchasers, will be subject to certain of the civil
liability provisions under the Securities Act in connection with such sales
and will be bound by the provisions of the Registration Rights Agreement
applicable to such holder (including certain indemnification and contribution
obligations).
 
  If (i) the Company fails to file any of the registration statements required
by the Registration Rights Agreement on or before the date specified for such
filing, (ii) any of such registration statements are not declared effective by
the Commission on or prior to the date specified for such effectiveness (the
"Effectiveness Target Date"), subject to certain limited exceptions, (iii) the
Company fails to consummate the Exchange Offer within 30 days of the
Effectiveness Target Date with respect to the Exchange Offer Registration
Statement or (iv) the Shelf Registration Statement or the Exchange Offer
Registration Statement is declared effective but thereafter, subject to
certain limited exceptions, ceases to be effective or usable in connection
with the Exchange Offer or resales of Transfer Restricted Notes, as the case
may be, during the periods specified in the Registration Rights Agreement
(each such event referred to in clauses (i) through (iv) above, a
"Registration Default"), then the interest rate on the Transfer Restricted
Notes will accrue at a rate per annum equal to an additional one quarter of
one percent (0.25%) of the principal amount of the Notes upon the occurrence
of each Registration Default, which rate will increase by one quarter of one
percent (0.25%) each 90-day period that such Additional Interest continues to
accrue under any such circumstance, with an aggregate maximum increase in the
interest rate equal to one percent (1%) per annum. Following the cure of all
Registration Defaults, the accrual of additional interest will cease and the
interest rate will revert to the original rate.
 
  The summary herein of certain provisions of the Registration Rights
Agreement does not purport to be complete and is subject to, and is qualified
in its entirety by reference to, all the provisions of the Registration Rights
Agreement, a copy which is filed as an exhibit to the Registration Statement
of which this Prospectus forms a part.

                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
  The following discussion summarizes the material federal income tax
considerations of the issuance of New Notes and the Exchange Offer. This
summary does not discuss all aspects of federal income taxation that may be
relevant to particular holders of Note, especially in light of a holder's
personal investment circumstances, or to certain types of holders subject to
special treatment under the federal income tax laws (for example, life
insurance companies, tax-exempt organizations and foreign corporations and
individuals who are not citizens or residents of the United States) and does
not discuss any aspects of state, local or foreign taxation. This discussion
is limited to those holders who will hold the Notes as "capital assets"
(generally, property held for investment) within the meaning of Section 1221
of the Internal Revenue Code of 1986, as amended (the "Code").
 
  This summary is based upon laws, regulations, rulings and decisions now in
effect and upon proposed regulations, all of which are subject to change
(possibly with retroactive effect) by legislation, administrative action or
judicial decision.
 
  EXCHANGE OFFER. The exchange of Old Notes for New Notes pursuant to the
Exchange Offer should not be treated as a taxable "exchange" because the New
Notes should not be considered to differ materially in kind or extent from the
Old Notes. Rather, the New Notes received by a holder of the Old Notes should
be treated as a continuation of the Old Notes in the hands of such holder. As
a result, there should be no gain or loss to holders exchanging the Old Notes
for the New Notes pursuant to the Exchange Offer.
 
  INTEREST. A holder will be required to include in gross income the stated
interest on the Old Notes or the New Notes in accordance with the holder's
method of tax accounting.
 
  TAX BASIS. Generally, a holder's tax basis in an Old Note will initially be
the holder's purchase price for the Old Note and will be decreased by the
amount of any principal payments received. If a holder exchanges an Old Note
for a New Note pursuant to the Exchange Offer, the tax basis of the New Note
immediately after such exchange should equal the holder's tax basis in the Old
Note immediately prior to the exchange.
 
  SALE OR REDEMPTION. The sale, exchange, redemption or other disposition of
an Old Note or a New Note (other than pursuant to the Exchange Offer)
generally will be a taxable event. A holder generally will recognize gain or
loss equal to the difference between (i) the amount of cash plus the fair
market value of any property received upon such sale, exchange, redemption or
other taxable disposition of an Old Note or a New Note (other than in respect
of accrued interest thereon) and (ii) the holder's adjusted tax basis in such
Old Note or New Note. Such gain or loss generally will be capital gain or
loss, provided that the holder has held the Note as a capital asset. The
recently enacted Taxpayer Relief Act of 1997 made certain changes to the Code
with respect to taxation of capital gains of taxpayers other than
corporations. In general, the maximum tax rate for non-corporate taxpayers on
long-term capital gains has been lowered to 20% from the previous 28% rate for
most capital assets (including the Old or New Notes) held for more than 18
months. For taxpayers in the 15% regular tax bracket, the maximum tax rate on
long-term capital gains in now 10%. Capital gain on such assets for non-
corporate holders having a holding period of more than one year but not more
than 18 months will be subject to a maximum tax rate of 28%. The holding
period of each New Note would include the holding period of the Old Notes
exchanged therefor.
 
  PURCHASERS OF NOTES AT OTHER THAN ORIGINAL ISSUANCE. The foregoing summary
does not discuss special rules which may affect the treatment of purchasers
that acquire Notes other than at original issuance, including those provisions
of the Code relating to the treatment of "market discount" and "acquisition
premium." Any such Purchaser should consult its tax advisor as to the
consequences to him of the acquisition, ownership and disposition of Old Notes
and the New Notes.
 
  BACKUP WITHHOLDING. Unless a holder or other payee provides its correct
taxpayer identification number (employer identification number or social
security number) to the Company (as payor) and certifies that such number is
correct, under the federal income tax backup withholding rules, generally 31%
of (1) the interest paid
 
                                      95
<PAGE>
 
on the Notes, and (2) proceeds of sale or other disposition of the Notes must
be withheld and remitted to the United States Department of the Treasury.
Therefore, each holder should complete and sign the Substitute Form W-9
included so as to provide the information and certification necessary to avoid
backup withholding. However, certain exchanging holders (including, among
others, certain foreign individuals) are not subject to these backup
withholding and reporting requirements. In order for a foreign individual to
qualify as an exempt foreign recipient, that exchanging holder must submit a
statement, signed under penalties of perjury, attesting to that individual's
exempt foreign status.
 
  Withholding is not an additional federal income tax. Rather, the federal
income tax liability of a person subject to withholding will be reduced by the
amount of tax withheld. If withholding results in an overpayment of taxes, a
refund may be obtained from the Internal Revenue Service.
 
  THE FOREGOING SUMMARY IS INCLUDED HEREIN FOR GENERAL INFORMATION ONLY. EACH
HOLDER OF NOTES OR NEW NOTES SHOULD CONSULT SUCH HOLDER'S TAX ADVISOR AS TO
THE SPECIFIC TAX CONSEQUENCES TO SUCH HOLDER OF THE EXCHANGE OFFER, INCLUDING
THE APPLICATION OF AND EFFECT OF STATE, LOCAL, FOREIGN AND OTHER TAX LAWS.
 
                                      96
<PAGE>
 
                             PLAN OF DISTRIBUTION
 
  Pursuant to the Exchange Offer, each Participating Broker-Dealer must
acknowledge that it will deliver a prospectus in connection with any resale of
such New Notes. This Prospectus may be used by a Participating Broker-Dealer
in connection with resales of New Notes received in exchange for Old Notes
where such Old Notes were acquired as a result of market-making activities or
other trading activities. The Company has agreed that it will make this
Prospectus available to any Participating Broker-Dealer for use in connection
with any such resale and Participating Broker-Dealers shall be authorized to
deliver this Prospectus for a period not exceeding 180 days after the
Expiration Date.
 
  The Company will not receive any proceeds from any sales of the New Notes by
Participating Broker-Dealers. New Notes received by Participating Broker-
Dealers for their own account pursuant to the Exchange Offer may be sold from
time to time, in one or more transactions in the over-the-counter market, in
negotiated transactions, through the writing of options on the New Notes or a
combination of such methods of resale, at market prices prevailing at the time
of resale, at prices related to such prevailing market prices or at negotiated
prices. Any such resale may be made directly to purchasers or to or through
brokers or dealers who may receive compensation in the form of commissions or
concessions from such Participating Broker-Dealer or the purchasers of any
such New Notes. Any broker-dealer that resells New Notes that were received by
it for its own account pursuant to the Exchange Offer and any broker or dealer
that participates in a distribution of such New Notes may be deemed to be an
"underwriter" within the meaning of the Securities Act and any profit on any
such resale of New Notes and any commissions or concessions received by any
such persons may be deemed to be underwriting compensation under the
Securities Act. The Letter of Transmittal states that by acknowledging that it
will deliver and by delivering a prospectus, a Participating Broker-Dealer
will not be deemed to admit that it is an "underwriter" within the meaning of
the Securities Act.
 
  The Company will promptly send additional copies of this Prospectus and any
amendment or supplement to this Prospectus to any Participating Broker-Dealer
that reasonably requests such documents in the Letter of Transmittal. See "The
Exchange Offer."
 
                                 LEGAL MATTERS
 
  Certain legal matters with respect to the validity of the issuance of the
Notes offered hereby will be passed upon for the Company by Mayer, Brown &
Platt, Chicago, Illinois.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Board of Directors and Stockholders of
The GSI Group, Inc.:
  We have audited the accompanying consolidated balance sheets of The GSI
Group, Inc. and subsidiaries as of December 31, 1995 and 1996, and the related
consolidated statements of income, stockholders' equity and cash flows for
each of the three years in the period ended December 31, 1996. These
consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of The GSI
Group, Inc. and subsidiaries as of December 31, 1995 and 1996, and the results
of their operations and their cash flows for the years then ended, in
conformity with generally accepted accounting principles.

                     THE GSI GROUP, INC. AND SUBSIDIARIES
 
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                               DECEMBER 31, 1996
 
1. NATURE OF OPERATIONS
 
  The GSI Group, Inc. and its subsidiaries ( the "Company") manufacture grain
storage bins and accessories, swine and poultry confinement, ventilation and
feeding systems and poultry incubation systems and accessories used primarily
in the agricultural industry. The Company's headquarters and main
manufacturing facility is in Assumption, Illinois, with other facilities in
Illinois and North Carolina. In addition, the Company has operations in
Brazil, Malaysia, South Africa, The Netherlands and Mexico.
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Basis of Consolidation
 
  The consolidated financial statements includes the accounts of the Company
and its subsidiaries. All intercompany transactions have been eliminated.
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the
reporting period. Actual results could differ from those estimates.
 
 Cash and Cash Equivalents
 
  The Company considers all short-term investments with original maturities of
three months or less when acquired to be cash equivalents.
 
 Inventories
 
  Inventories are stated at the lower of cost or market. Cost includes the
cost of materials, labor and factory overhead. The cost of those inventories
was determined on the last-in, first-out method. Had the inventories been
determined on the first-in, first-out method at December 31, 1995 and 1996,
the reported value of such inventories would have been increased by $2.8
million and $3.3 million, respectively.
 
 Property, Plant and Equipment
 
  Property, plant and equipment is stated at cost less accumulated
depreciation. The cost of property, plant and equipment acquired as part of a
business acquisition represents the fair market value of such assets at the
acquisition date typically as determined by independent appraisal.
Depreciation is provided using the straight-line method by making periodic
charges to income over the estimated useful lives of the assets (5-10 years
for all property except for depreciable real property, which is depreciated
over 25 years).
 
  Property, plant and equipment under capital leases are amortized over the
shorter of the estimated useful life of the asset or the term of the lease.
 
  Maintenance and repairs are charged to expense as incurred, while major
replacements and improvements are capitalized. Maintenance and repair costs
were $2.7 million, $2.0 million and $2.1 million for the years ended

December 31, 1994, 1995 and 1996, respectively. The cost and accumulated
depreciation of items sold or retired are removed from the property accounts
and any gain or loss is recorded currently in the consolidated statements of
income.
 
 Research and Development
 
  Costs associated with research and development are expensed as incurred.
Such costs incurred were $1.1 million, $1.4 million and $1.2 million for the
years ended December 31, 1994, 1995 and 1996, respectively.
 
 Intangible Assets
 
  The excess of purchase costs over amounts allocated to identifiable assets
and liabilities of businesses acquired ("goodwill") is amortized on the
straight-line basis over 40 years. Should events or circumstances occur
subsequent to the acquisition of a business which bring into question the
realizable value or impairment of the related goodwill, the Company will
evaluate the remaining useful life and balance of goodwill and make
appropriate adjustments. The Company's principal considerations in determining
impairment include the strategic benefit to the Company of the particular
business as measured by undiscounted current and expected future operating
cash flows of that particular business and expected undiscounted cash flows.
Should an impairment be identified, a loss would be reported to the extent
that the carrying value of the related goodwill exceeds the fair value of that
goodwill as determined by valuation techniques available in the circumstances.
 
 Revenue Recognition
 
  Revenue on all products are recorded when products are completed and
shipped.
 
 Translation of Foreign Currency
 
  The Company translates the financial statements of its foreign subsidiaries
in accordance with Statement of Financial Accounting Standards ("SFAS") No.
52, "Foreign Currency Translation." The cumulative translation adjustment and
translation loss were immaterial to the consolidated financial statements.
 
 Earnings Per Share
 
  Earnings per common share are computed by dividing earnings by the weighted
average number of common shares outstanding during each period. See Note 6.
 
 Income Taxes
 
  Effective February 1988, an election was filed with the Internal Revenue
Service to have taxable income of the Company taxed to the individual owners
pursuant to S Corporation provisions of the Internal Revenue Code.
Accordingly, no provision for federal income taxes has been recorded.
Dividends sufficient to pay the resulting income taxes of the owners are
declared and paid as needed. The Company is responsible for certain state
taxes.
 
 New Accounting Pronouncements
 
  SFAS No. 128, "Earnings Per Share," was issued in February 1997 and will be
adopted by the Company effective January 1, 1998. This new pronouncement
establishes revised methods for computing and reporting earnings per share.
Adoption of this standard will not materially impact previously reported
earnings per share.
 
  SFAS No. 130, "Reporting Comprehensive Income," was issued in July 1997 and
will be adopted by the Company effective January 1, 1998. This new
pronouncement establishes standards for reporting and display of

 Reclassification
 
  Certain reclassifications have been made to prior-year amounts to conform to
the current-year presentation.
 
3. DISCONTINUED OPERATIONS
 
  In 1995, in order to concentrate on its core businesses, the Company made a
decision to sell its Heritage Vinyl Products Division ("Division"). The
agreement to sell the Division was signed in December 1995 and the sale of the
Division closed on January 11, 1996. The sale of the net assets of the
Division resulted in net proceeds to the Company of $8.0 million. The gain on
the sale was $2.8 million. The Company restated 1994 consolidated financial
statements to present continuing operations and the discontinued operations of
the Division. A charge of $482,000 was recorded in 1996 to adjust certain
retained assets to net realizable value.

  The long-term debt agreements provide for certain restrictive financial and
non-financial covenants. The more significant of these covenants require the
maintenance of certain levels of working capital, net worth, dividend
payments, cash flow coverage and current ownership structure.
 
  Costs associated with obtaining the debt described above aggregate to $0.3
million and $0.4 million as of December 31, 1995 and 1996, respectively.
Amortization of deferred financing costs amounted to $0.1 each year for each
of the years ended December 31, 1994, 1995 and 1996. As of December 31, 1995
and 1996, accumulated amortization of such costs was $0.1 million and $0.2
million, respectively.
 
  The fair value of long-term debt approximates carrying value based on
borrowing rates currently available to the Company for borrowing with similar
terms and maturities.
 
8. EMPLOYEE BENEFIT PLANS
 
  On December 31, 1995, the Company terminated its profit sharing plan. The
plan's assets were distributed at the direction of the account holders. Under
this plan, the Company's contribution was discretionary. The Company made
contributions of $212,000 during 1994 and made no contributions to this plan
during 1995.
 
  On January 1, 1996, the Company created a defined contribution plan covering
virtually all full-time employees. Under the plan, Company contributions are
discretionary. During 1996, the Company provided a 25% matching contribution
up to 1% of the employees' compensation. Employer contributions to this plan
were $79,000 during 1996.
 
  On July 1, 1996, certain employees were granted individual amounts of
"gainshares" based on several factors, including experience and
responsibilities. This program, which terminates December 31, 1997, provides
for participating employees to receive 40% of the pre-tax profits (as defined
by the stockholders) that are in excess of 5% of net sales. Each participating
employee's portion is calculated based on the number of shares held divided by
the total number of shares provided. Total expense for 1996 was $2.3 million.
 
9. COMMITMENTS AND CONTINGENCIES
 
  The Company is involved in various legal matters arising in the normal
course of business which, in the opinion of management, will not have a
material effect on the Company's financial position or results of operations.
 
  The Company has month by month leases for several buildings and paid rentals
in 1995 and 1996 of $131,880 and $592,000, respectively. The Company leases
various other items of equipment and vehicles under operating lease
arrangements. Total lease expense for the years ended December 31, 1994, 1995
and 1996, was $2.3 million, $3.1 million and $2.1 million, respectively.

NOTE 1--BASIS OF PRESENTATION
 
  The accompanying unaudited condensed consolidated financial statements have
been prepared in accordance with generally accepted accounting principles for

information and footnotes required by generally accepted accounting principles
for a complete set of financial statements. In the opinion of management, all
adjustments considered necessary for a fair presentation (consisting of normal
recurring accruals) have been included. As interim periods are not necessarily

notes thereto included in this Offering Memorandum.
 
  The consolidated financial statements include the accounts of The GSI Group,
Inc. and its subsidiaries (the "Company"). All significant intercompany
transactions and accounts have been eliminated in the accompanying

                     THE GSI GROUP, INC. AND SUBSIDIARIES
 
       NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
  The Company maintains a line-of-credit that has a maximum borrowing level of
$37.6 million as of September 30, 1997 based upon accounts receivable and
inventory and secured by accounts receivable, inventories and certain
equipment. Interest is at variable rates based on floating prime rate plus
one-half or LIBOR-based rates as of December 31, 1996 and a floating prime
rate or LIBOR based rate as of September 30, 1997 (8.75% and 8.00%,
respectively, at December 31, 1996 and 8.5% and 7.6%, respectively at
September 30, 1997.) Outstanding letters of credit, which reduce the overall
level of borrowing, as of December 31, 1996 and September 30, 1997 were $3.9
million each period, respectively which reduces the overall availability of
the line to $5.2 million at December 31, 1996 and $0.9 million at September
30, 1997. The line of credit matures on May 31, 1999.
 
  The Company has a term note payable at variable interest based on a floating
prime rate plus one or LIBOR-based rate (9.25% and 8.53%, respectively, at
December 31, 1996 and 9.5% and 8.8%, respectively, at September 30, 1997.) The
payable is secured by accounts receivable, inventories and certain equipment
and is due June, 2001.
 
  The line-of-credit agreement provides certain restrictive financial and non-
financial covenants including maintenance of certain levels of capital
spending and cash flow coverage.
 
NOTE 6--EARNINGS PER SHARE
 
  Earnings (loss) per common share have been computed based on the weighted
average common shares outstanding. Primary and fully diluted earnings (loss)
per share are the same.
 
NOTE 7--SUBSEQUENT EVENTS
 
  In November 1997, the Company anticipates issuing $100 million of Senior
Subordinated Notes ("Notes"), which will be due 2007. The Notes will represent
unsecured senior subordinated obligations of the Company. The Notes have
customary restrictive covenants including restrictions of incurrence of
additional indebtedness and limitations on dividends and other payments
affecting subsidiaries. Upon occurrence of a change in control (as defined),
the Company is required to repurchase the Notes at a price equal to 101% of
the principal amount thereof plus accrued and unpaid interest, if any, to the
date of purchase.
 
  The Company entered into a stock purchase agreement dated October 10, 1997
to acquire David Manufacturing Co. ("DMC") for approximately $19.3 million in
cash. DMC is a manufacturer and supplier of grain drying and handling
equipment. The acquisition, which will be accounted for as a purchase, is
expected to close on November 5, 1997.

To the Board of Directors
David Manufacturing Co.
Mason City, Iowa
 
  We have audited the accompanying balance sheet of David Manufacturing Co. as
of October 31, 1996, and the related statements of income, stockholders'
equity, and cash flows for the year then ended. These financial statements are
the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audit.
 
  We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of David Manufacturing Co. as
of October 31, 1996, and the results of its operations and its cash flows for
the year then ended, in conformity with generally accepted accounting
principles.

NOTE 1. NATURE OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES
 
  Nature of business: The Company manufactures and sells grain handling and
drying equipment to dealers.
 
    Sales are made on credit terms established by the Company. The Company's
  customers are concentrated in the agricultural industry and are located
  throughout the Midwest.
 
 Significant accounting policies:
 
    Accounting estimates and assumptions: The preparation of financial
  statements in conformity with generally accepted accounting principles
  requires management to make estimates and assumptions that effect the
  reported amounts of assets and liabilities and disclosure of contingent
  assets and liabilities at the date of the financial statements and the
  reported amounts of revenue and expenses during the reporting period.
  Actual results could differ from those estimates.
 
    Cash and cash equivalents: For purposes of reporting cash flows, the
  Company considers all highly liquid debt instruments purchased with a
  maturity of three months or less to be cash equivalents. The Company
  maintains cash in bank deposit accounts, which at times may exceed
  federally insured limits. The Company has not experienced any losses in
  such accounts.
 
    Inventories: Inventories are valued at the lower of cost, as determined
  by the last-in, first-out (LIFO) method, or market.
 
    Property and equipment: Property and equipment is stated at cost.
  Depreciation is computed primarily by the straight-line method over the
  following estimated useful lives:

                                                                           -----

</TABLE>
 
    Patent rights: Patent rights are being amortized by the straight-line
  method over a period of twelve years and are periodically reviewed for
  impairment based upon an assessment of future operations to ensure that
  they are appropriately valued. Accumulated amortization on patent rights
  totaled $19,798 and $31,260 at October 31, 1996 and September 30, 1997,
  respectively.
 
    Warranty claims: Estimated warranty costs are provided at the time of
  sale of the warranted products.
 
    Revenue recognition: Revenue is recognized when the products are shipped.
 
    Income taxes: Deferred taxes are provided on a liability method whereby
  deferred tax assets are recognized for deductible temporary differences and
  deferred tax liabilities are recognized for taxable temporary differences.
  Temporary differences are the differences between the reported amounts of
  assets and liabilities and their tax bases. Deferred tax assets are reduced
  by a valuation allowance when, in the opinion of management, it is more
  likely than not that some portion or all of the deferred tax assets will
  not be realized. Deferred tax assets and liabilities are adjusted for the
  effects of changes in tax laws and rates on the date of enactment.
 
    Earnings per common share: Earnings per common share are determined by
  dividing net income by the weighted average number of shares outstanding.
 
    New accounting pronouncements: SFAS No. 128, "Earnings Per Share," was
  issued in February 1997 and will be adopted by the Company effective
  January 1, 1998. This new pronouncement establishes revised methods for
  computing and reporting earnings per share. Adoption of this standard will
  not materially impact previously reported earnings per share.
 
    SFAS No. 130, "Reporting Comprehensive Income," was issued in July 1997
  and will be adopted by the Company effective January 1, 1998. This new
  pronouncement establishes standards for reporting and

  display of comprehensive income and its components. Adoption of this
  standard will not impact the Company's financial position or results of
  operations.
 
    Interim Financial Information (unaudited): The financial statements as of
  September 30, 1997, and for the eleven month periods ended September 30,
  1997 and 1996, are unaudited, but in the opinion of management included all
  adjustments, consisting only of normal recurring adjustments, necessary for
  a fair presentation of the financial position and results of operations.
  The operating results for the interim periods are not indicative of the
  operating results to be expected for a full year or for other interim
  periods. Not all disclosures required by generally accepted accounting
  principles necessary for a complete presentation have been included.
 
NOTE 2. PLEDGED ASSETS, NOTE PAYABLE AND LONG-TERM DEBT
 
  The Company has a revolving line of credit with a bank whereby outstanding
borrowings may not exceed the lesser of the borrowing base defined as a
percentage of eligible accounts receivable and inventory or $6,250,000.
Interest is payable monthly at the bank's base rate plus variable percentage
points based on achieving certain financial ratios (currently 9.0%).
Outstanding borrowings ($600,000 as of October 31, 1996) are due March 31,
1997. As of October 31, 1996 the remaining available borrowing base on this
line of credit was $5,400,000. The line of credit is collateralized by all
assets of the Company and the personal guarantees of Mr. Wesley Cagle, Mr.
Stephen Wolfe, and Mr. Keith Braun up to $150,000 each, plus interest and all
costs of collection. A letter of credit of $250,000 is available as part of
the revolving line of credit. The loan agreement contains various
restrictions, including restrictions on the payment of dividends, expenditures
for property and equipment and the maintenance of various financial ratios
including debt to tangible net worth. At October 31, 1996, the Company was in
compliance with all loan covenants.
 
  The Company has a balance due of $1,167,644 on an unsecured contract payable
to David M. Murphy. The contract is due in monthly installments of $17,114
including interest at 6.1%, with final payment due October 1, 2003. The
contract payable is subordinated to bank debt; however, such subordination
will permit payment of principal and interest, so long as no event of default
has occurred under the credit agreement.
 
  Approximate maturities of long-term debt are as follows:

  Based on the borrowings rates currently available to the Company for bank
loans with similar terms and average maturities, the fair value of the note
payable approximates its carrying value and the fair value of the long-term
debt is approximately $1,065,000.

  The liquidation of LIFO inventory quantities during the year ended October
31, 1996, which were carried at the lower of cost prevailing in certain
earlier years, resulted in an increase in the net income for the year ended

stock.

NOTE 7. AFFILIATED COMPANY
 
  Effective January 1, 1995, the Company became affiliated with the David
Service Company, a foreign DISC corporation, as a result of having common
stockholders and management. The Company has an agreement with the David
Service Company whereby a commission of up to 50% of net export profits can be
paid by the Company to the DISC corporation. For the year ended October 31,
1996, the commission expense totaled $196,442.
 
NOTE 8. UNION REPRESENTATION AT DMC
 
  After an impasse in negotiations during a five week strike beginning March
13, 1996, replacement workers were hired for those refusing to come back to
work under the Company's final offer.
 
  A petition for a vote of decertification was signed by 51 percent of the
workers and submitted by them to the NLRB (National Labor Relations Board).
Just prior to the scheduled vote, the Company was sent a letter by the Union
stating they were no longer interested in representing the workers at DMC.
This negated the vote and left DMC employees without union representation. The
workplace is now union free.

                    INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  Section 145 of the Delaware General Corporation Law ("Section 145") permits
indemnification of directors, officers, agents and controlling persons of a
corporation under certain conditions and subject to certain limitations.
Section 145 empowers a corporation to indemnify any person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative
or investigative (other than an action by or in the right of the corporation),
by reason of the fact that he is or was a director, officer, employee or agent
of the corporation or another enterprise if serving at the request of the
corporation. Depending on the character of the proceeding, a corporation may
indemnify against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred in connection with
such action, suit or proceeding if the person indemnified acted in good faith
and in a manner be reasonably believed to be in or not opposed to, the best
interests of the corporation, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe his conduct was unlawful. In
the case of an action by or in the right of the corporation, no
indemnification may be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the corporation
unless and only to the extent that the Court of Chancery or the court in which
such action or suit was brought shall determine that, despite the adjudication
of liability, such person is fairly and reasonably entitled to indemnity for
such expenses which the court shall deem proper. Section 145 further provides
that to the extent a director or officer of a corporation has been successful
in the defense of any action, suit or proceeding referred to above or in the
defense of any claim, issue or matter therein, he shall be indemnified against
expenses (including attorneys' fees) actually and reasonably incurred by him
in connection therewith. In addition, pursuant to Article SEVENTH of the
Company's Amended and Restated Certificate of Incorporation, a director will
not be liable to the Company or its stockholders for monetary damages for
breach of fiduciary duty as a director. Article EIGHTH of the Company's
Amended and Restated Certificate of Incorporation provides that with respect
to threatened, pending or completed actions, suits or proceedings to which any
individual is made a party by reason of such individual being or having been a
director, officer, employee or agent of the Company, or is or was serving at
the request of the Company as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
the Company has the power to indemnify such persons, provided that such person
in general, acted in good faith and in the best interests of the Company.
 
  The Company maintains a directors' and officers' liability insurance policy
which insures directors and officers of the Company and officers of the
Company and its subsidiaries for losses as a result of claims based upon their
acts or omissions in the discharge of their duties as directors and officers
of the Company and its subsidiaries.
 
  Sections 851 and 856 of the Iowa Business Corporation Act ("IBCA") provide
that a corporation has the power to indemnify its directors and officers
against liabilities and expenses incurred by reason of such person serving in
the capacity of director or officer, if such person has acted in good faith
and in a manner reasonably believed by the individual to be in or not opposed
to the best interests of the corporation, and in any criminal proceeding if
such person had no reasonable cause to believe the individual's conduct was
unlawful. The foregoing indemnity provisions notwithstanding, in the case of
actions brought by or in the right of the corporation, no indemnification
shall be made to such director or officer with respect to any matter as to
which such individual has been adjudged to be liable to the corporation
unless, and only to the extent that, a court determines that indemnification
is proper under the circumstances. DMC's Bylaws provide indemnification for
its officers and directors to the extent permitted by the IBCA. DMC's Bylaws
also provide that DMC shall indemnify any of its directors and officers who
are wholly successful, on the merits or otherwise, in the defense of any
proceeding to which such directors or officers were parties, because of the
fact that such directors or officers are or were directors or officers of DMC,
against reasonable expenses incurred by such directors and officers in
connection with such proceeding.
 
  DMC maintains a directors' and officers' liability insurance policy to
insure against losses arising from claims made against its directors and
officers, subject to the limitations and conditions as set forth in the
policies.

ITEM 22. UNDERTAKINGS
 
  Each of the undersigned registrants hereby undertakes:
 
  Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the
registrant in the successful defense of any action, suit or proceeding) is
asserted by such director, officer or controlling person in connection with
the securities being registered, the registrant will, unless in the opinion of
its counsel the matter has been settled by controlling precedent, submit to a
court of appropriate jurisdiction the question whether such indemnification by
it is against public policy as expressed in the Act and will be governed by
the final adjudication of such issue.
 
  (a) Each of the undersigned registrants hereby undertakes:
 
    (1) To file, during any period in which offers or sales are being made, a

      (iii) To include any material information with respect to the plan of
    distribution not previously disclosed in the registration statement or
    any material change to such information in the registration statement.
 
    (2) That, for the purpose of determining any liability under the
  Securities Act of 1933, each such post-effective amendment shall be deemed
  to be a new registration statement relating to the securities offered
  therein, and the offering of such securities at that time shall be deemed
  to be the initial bona fide offering thereof.
 
    (3) To remove from registration by means of a post-effective amendment
  any of the securities being registered which remain unsold at the
  termination of the offering.
 
  (b) Each of the undersigned registrants hereby undertakes:
 
    (1) To respond to requests for information that is incorporated by
  reference into the Prospectus pursuant to Item 4, 10(b), 11 or 13 of this

          SECTION 1.  Representations and Warranties.
                      ------------------------------ 

          (a)  The Company represents and warrants to each Initial Purchaser as
of the date hereof and as of the Closing Time, and agrees with each Initial
Purchaser as follows:

               (i)  Similar Offerings.  The Company has not, directly or
                    -----------------                                    
     indirectly, solicited any offer to buy or offered to sell, and will not,
     directly or indirectly, solicit any offer to buy or offer to sell, in the
     United States or to any United States citizen or resident, any security
     which is or would be integrated with the sale of the Securities in a manner
     that would require the Securities to be registered under the 1933 Act.

               (ii) The Preliminary Offering Memorandum as of its date did not,
     and the Final Offering Memorandum as of the date hereof does not, and at
     the Closing Time the Final Offering Memorandum will not, include an untrue
     statement of a material fact or omit to state a material fact necessary in
     order to make the statements therein, in the light of the circumstances
     under which they were made, not misleading; provided, however, that this
     representation, warranty and agreement shall not apply to statements in or
     omissions from the Preliminary Offering Memorandum or the
<PAGE>
 
                                      -4-

     Final Offering Memorandum made in reliance upon and in conformity with
     information furnished to the Company in writing by any Initial Purchaser
     through Merrill Lynch expressly for use therein.

               (iii)  Arthur Andersen LLP and McGladrey & Pullen, LLP who
     certified the financial statements and supporting schedules included in the
     Offering Memorandum with respect to the Company and its subsidiaries and
     David Manufacturing Co., respectively, are independent certified public
     accountants within the meaning of Regulation S-X under the 1933 Act.

               (iv)   The financial statements, together with the related
     schedules and notes, included in the Offering Memorandum present fairly in
     all material respects the financial position of the Company and its
     consolidated subsidiaries at the dates indicated and the statement of 
     operations, stockholders' equity and cash flows of the Company and its
     consolidated subsidiaries and David Manufacturing Co. for the periods
     specified; said financial statements have been prepared in conformity with
     generally accepted accounting principles ("GAAP") applied on a consistent
                                                ----                           
     basis throughout the periods involved.  The supporting schedules, if any,
     included in the Offering Memorandum present fairly in accordance with GAAP
     the information required to be stated therein.  The selected consolidated
     financial data and the summary consolidated financial data included in the
     Offering Memorandum present fairly the information shown therein and have
     been compiled on a basis consistent with that of the audited financial
     statements included in the Offering Memorandum.  The statistical
     information and other market-related data included in the Offering
     Memorandum present fairly, in all material respects, the information and
     data shown therein and are derived from sources the Company believes are
     accurate in all material respects.  The pro forma financial information
     relating to the Company and its subsidiaries and the related notes thereto
     included in the Offering Memorandum present fairly in all material respects
     the in formation shown therein, have been prepared in all material
     respects in accordance with the Commission's rules and guidelines with
     respect to pro forma financial adjustments and have been properly computed
     on the bases described therein, and the assumptions used in the
     preparation thereof are reasonable and the adjustments used therein are
     appropriate to give effect to the transactions and circumstances referred
     to therein.

     taken, directly or indirectly, any action designed, or which might
     reasonably be expected to cause or result, under the 1934 Act, in, or which

     Securities, the Exchange Securities or the Private Exchange Securities.

          (b)  Any certificate signed by any officer of the Company or any of

          SECTION 2.  Sale and Delivery to Initial Purchasers; Closing.
                      ------------------------------------------------ 

          (a)  On the basis of the representations and warranties herein
contained and subject to the terms and conditions herein set forth, the Company
agrees to sell to each Initial Purchaser, severally and not jointly, and each
Initial Purchaser, severally and not jointly, agrees to purchase from the
Company, at the price set forth in Schedule B hereto, the aggregate principal
                                   ----------                                 
amount of Securities set forth in Schedule A hereto opposite the name of such
                                  ----------                                 
Initial Purchaser, plus any additional principal amount of Securities such
Initial Pur chaser may become obligated to purchase pursuant to the provisions
of Section 11 hereof.

          (b)  Payment of the purchase price for, and delivery of certificates
in definitive form for, the Securities shall be made at the offices of Mayer
Brown & Platt, 190 South LaSalle Street, Chicago, Illinois, or at such other
place as shall be agreed upon by Merrill Lynch and the Company, at 9:00 A.M.,
Central Standard Time, on November 5, 1997 (unless postponed in accordance with
the provisions of Section 11), or such other time not later than ten business
days after such date as shall be agreed upon by Merrill Lynch and the Company
(such time and date of payment and delivery being herein called the "Closing
                                                                     -------
Time").
- ----   

          Payment shall be made to the Company by wire transfer of immediately
available funds to a bank account designated by the Company, against delivery in
accordance with the DTC Agreement to Merrill Lynch for the respective accounts
of the Initial Purchasers of certificates for the Securities to be purchased
by them.  It is understood that each Initial Purchaser has authorized Merrill
Lynch, for its account, to accept delivery of, receipt for, and make payment of
the purchase price for, the Securities which it has agreed to purchase.  Merrill
Lynch, individually and not as representative of the Initial Purchasers, may
(but shall not be obligated to) make payment of the purchase price for the
Securities to be purchased by any Initial Purchaser whose funds have not been
received by, the Closing Time, but such payment shall not relieve such Initial
Purchaser from its obligations hereunder.  The certificates representing the
Securities shall be registered in such names and in such denominations ($1,000
or integral multiples thereof) as the Initial Purchasers may request not later
than 10:00 A.M., New York City time, on the second business day prior to the
Closing Time and shall be made available for ex amination and packaging by the
Initial Purchasers in New York,

New York not later than 10:00 A.M, New York City time, on the last business day
prior to the Closing Time.

          (c)  Each Initial Purchaser, severally and not jointly, represents and
warrants to, and agrees with, the Company that it is a "qualified institutional
buyer" within the meaning of Rule 144A under the 1933 Act (a "Qualified
                                                              ---------
Institutional Buyer").

          SECTION 3.  Covenants of the Company.  The Company covenants with
                      ------------------------                             
each Initial Purchaser as follows:

          (a)  The Company has furnished or, as promptly as possible, will
     furnish to each Initial Purchaser, without charge, such number of copies of
     the Preliminary Offering Memorandum, the Final Offering Memorandum and any
     amendments and supplements thereto as such Initial Purchaser may
     reasonably request.

          (b)  The Company will immediately notify each Initial Purchaser, and
     confirm such notice in writing, of (x) any filing made by the Company of
     information relating to the offering of the Securities with any securities
     exchange or any other regulatory body in the United States or any other
     jurisdiction.  If prior to the completion of the placement of the
     Securities by the Initial Purchasers as evidenced by a notice in writing
     from the Initial Purchasers to the Company (from the date hereof to such
     completion, the "Offering Period"), any event shall occur as a result of
                      ---------------                                        
     which it is necessary, in the reasonable opinion of the Company, its
     counsel, the Initial Purchasers or counsel for the Initial Purchasers, to
     amend or supplement the Offering Memorandum in order that the Offering
     Memorandum not include any untrue statement of a material fact or omit to
     state a material fact necessary in order to make the statements therein, in
     the light of the circumstances then existing, not misleading or if, in the
     opinion of the Company, its counsel, the Initial Purchasers, or counsel
     for the Initial Purchasers, such amendment or supplement is necessary to
     comply with applicable law, the Company will (subject to Section 3(c)
     hereof) forthwith amend or supplement the Offering Memorandum by preparing
     and furnishing to each Initial Purchaser an amendment or amendments of, or
     a supplement or supplements to, the Offering Memorandum (in such number as
     the Initial Purchasers may reasonably request), at its own expense, so
     that, as so amended or supplemented, the Offering Memorandum will not
     include an untrue statement of a material fact or
<PAGE>
 
                                     -17- 

     omit to state a material fact necessary in order to make the statements
     therein, in the light of the circumstances existing at the time it is
     delivered to a Subsequent Purchaser, not misleading or so that the Offering
     Memorandum, as so amended or supplemented, shall comply with applicable
     law, as the case may be.

          (c)  The Company will advise each Initial Purchaser promptly of any
     proposal to amend or supplement the Offering Memorandum during the
     Offering Period and will not effect such amendment or supplement without
     the prior written consent of the Initial Purchasers.  Neither the consent
     of the Initial Purchasers, nor the Initial Purchasers' delivery of any
     such amendment or supplement, shall constitute a waiver of any of the
     conditions set forth in Section 5 hereof.

          (d)  The Company will use its best efforts, in cooperation with the
     Initial Purchasers, to qualify the Securities for offering and sale under
     the applicable securities laws of such jurisdictions as the Initial
     Purchasers may designate and will maintain such qualifications in effect
     as long as required for the resale of the Securities by the Initial
     Purchasers as contemplated herein; provided, however, that the Company
     shall not be obligated to file any general consent to service of process or
     to qualify as a foreign corporation or as a dealer in securities in any
     jurisdiction in which it is not so qualified or to subject itself to
     taxation in respect of doing business in any jurisdiction in which it is
     not otherwise so subject.

          (e)  The Company shall take all reasonable action necessary to enable
     Standard & Poor's Ratings Group, a division of McGraw Hill, Inc. ("S&P"),
                                                                        ---   
     and Moody's Investors Service, Inc. ("Moody's") to provide their respective

     credit ratings of the Securities.

          (f)  The Company will cooperate with the Initial Purchasers and use
     its best efforts to permit the Securities to be eligible for clearance and
     settlement through the facilities of DTC and to be designated as "PORTAL
     Securities" in accordance with the rules and regulations of the National
     Association of Securities Dealers, Inc. ("NASD").
                                               ----   

          (g)  The Company will use the net proceeds received by it from the
     sale of the Securities in the manner specified in the Offering Memorandum
     under the heading "Use of Proceeds."

                                     -18-

          (h)  The Company agrees that, in order to render the Securities
     eligible for resale pursuant to Rule 144A under the 1933 Act, unless the
     Company furnishes information to the Commission pursuant to Section 13 or
     15(d) of the 1934 Act, so long as any of the Securities, including the Ex
     change Securities and Private Exchange Securities, remain outstanding and
     not subject to an effective registration statement under the 1933 Act, it
     will make available, upon request, to any holder of Securities or
     prospective pur chasers of Securities the information specified in Rule
     144A(d)(4) (such information, whether made available to holders or
     prospective purchasers or furnished to the Commission, is herein referred
     to as "Additional Information").
            -----------------------   

          (i)  In connection with the original distribution of the Securities,
     the Company agrees that, prior to any offer or resale of the Securities by
     the Initial Purchasers, the Initial Purchasers and counsel for the Initial
     Purchasers shall have the right to make reasonable inquiries into the
     business of the Company and the Subsidiaries.  The Company also agrees to
     provide answers to each prospective Subsequent Purchaser of Securities who
     so requests concerning the Company and the Subsidiaries (to the extent
     that such information is available or can be acquired and made available
     to prospective Subsequent Purchasers without unreasonable effort or
     expense and to the extent the provision thereof is not prohibited by
     applicable law and would not involve the disclosure of confidential
     information of the Company) and the terms and conditions of the offering
     of the Securities, as provided in the Offering Memorandum.

          (j)  Until the expiration of two years after the original issuance of
     the Securities, the Company will not, and will cause its Affiliates not to,
     purchase or agree to purchase or otherwise acquire any Securities which are
     "restricted securities" (as such term is defined under Rule 144(a)(3) under
     the 1933 Act), whether as beneficial owner or otherwise (except as agent
     acting as a securities broker on behalf of and for the account of customers
     in the ordinary course of business in unsolicited broker's transactions)
     unless, upon any such purchase, the Company or any such Affiliate shall
     submit such Securities to the Trustee for cancellation.

          (k)  During a period of 180 days from the date of the Offering
     Memorandum, the Company will not, without the
<PAGE>
 
                                     -19-

     prior written consent of Merrill Lynch, directly or indirectly, issue,
     sell, offer or agree to sell, grant any option for the sale of, or
     otherwise dispose of, any other debt securities of the Company or
     securities of the Company convertible into, or exchangeable for, the
     Securities or such other debt securities, except for the Exchange
     Securities and the Private Exchange Securities.

          SECTION 4.  Payment of Expenses.
                      ------------------- 

          (a)  The Company will pay all expenses incident to the performance of

including the reasonable fees and disbursements of counsel for the Initial

Purchasers for the loss of anticipated profits from the transactions
contemplated by this Agreement.

and agree to observe the following procedures in connection with the offer and

               (i)  Offers and sales of the Securities will be made only by the
     Initial Purchasers or affiliates thereof qualified to do so in the
     jurisdictions in which such offers or sales are made.  Each such offer or
     sale shall only be made (A), in the case of Securities resold or otherwise
     transferred pursuant to Rule 144A, to persons whom the offeror or seller
     reasonably believes to be Qualified
<PAGE>
 
                                     -23-

     Institutional Buyers or (B) to non-U.S. persons outside the United States
     to whom the offeror or seller reasonably believes offers and sales of the
     Securities may be made in reliance upon Regulation S under the 1933 Act.

               (ii)   The Securities will be offered by approaching prospective
     Subsequent Purchasers on an individual basis.  No general solicitation or
     general advertising (within the meaning of Rule 502(c) under the 1933 Act)
     will be used in the United States in connection with the offering of the
     Securities.

               (iii)  In the case of a non-bank Subsequent Purchaser of a
     Security acting as a fiduciary for one or more third parties, in connection
     with an offer and sale to such purchaser pursuant to clause (i) above,
     each third party shall, in the judgment of the applicable Initial Pur
     chaser, be a Qualified Institutional Buyer or a non-U.S. person outside the
     United States.

               (iv)   Each Initial Purchaser acknowledges and will take
     reasonable steps to inform, and cause each of its United States affiliates
     to take reasonable steps to inform, persons acquiring Securities from such
     Initial Purchaser or affiliate, as the case may be, in the United States
     that the Securities (A) have not been and will not be registered under the
     1933 Act, (B) are being sold to them without registration under the 1933
     Act in reliance on Rule 144A or Regulation S under the 1933 Act and (C) may
     not be offered, sold or otherwise transferred prior to (x) the date which
     is two years (or such shorter time as is permitted by Rule 144(k) under the
     1933 Act or any successor provision thereunder) after the later of the
     date of the original issue of the Securities and the last date on which the
     Company or any affiliate of the Company was the owner of such Securities or
     any predecessor thereto or (y) such later date, if any, as may be required
     by applicable law, except (1) to the Company, (2) for so long as such
     Securities are eligible for resale pursuant to Rule 144A, to a person it
     reasonably believes is a Qualified Institutional Buyer that purchases such
     Securities for its own account or for the account of a Qualified 
     Institutional Buyer to whom notice is given that the transfer is being made
     in reliance on Rule 144A, (3) pursuant to offers and sales to persons who
     are not U.S. Persons (as defined in Regulation S under the 1933 Act) that
     occur outside the United States pursuant to Regulation S under the 1933
     Act, (4) pursuant to an effective registration state-
<PAGE>
 
                                     -24-

     ment under the 1933 Act or (5) pursuant to another available exemption
     from the registration requirements of the 1933 Act.

               (v)    No sale of the Securities to any one Subsequent Purchaser
     will be for less than $100,000 principal amount and no Security will be
     issued in a smaller principal amount.  If any Subsequent Purchaser is a
     non-bank fiduciary acting on behalf of others, each person for whom it is
     acting must purchase at least $100,000 principal amount of the Securities.

               (vi)   The transfer restrictions and the other provisions set
     forth in the Indenture, including the legend required thereby, shall apply
     to the Securities except as otherwise agreed by the Company and the Initial
     Purchasers.  Following the sale of the Securities by the Initial
     Purchasers to Subsequent Purchasers pursuant to and in compliance with the
     terms hereof, the Initial Purchasers shall not be liable or responsible to
     the Company for any losses, damages or liabilities suffered or incurred by
     the Company, including any losses, damages or liabilities under the 1933
     Act, arising from or relating to any resale or transfer of any Security
     occurring after such sale by the Initial Purchasers.

               (vii)  Each Initial Purchaser will deliver to each purchaser of
     the Securities from such Initial Purchaser, in connection with its original
     distribution of the Securities, a copy of the Offering Memorandum, as
     amended and supplemented at the date of such delivery.

          (b)  Each Initial Purchaser understands that the Securities have not
been and will not be registered under the 1933 Act and may not be offered or
sold within the United States or to, or for the account or benefit of, U.S.
persons except in accordance with Regulation S or Rule 144A under the 1933 Act
or pursuant to an exemption from the registration requirements of the 1933 Act.
Each Initial Purchaser represents and agrees, that, except as permitted by
Section 6(a) above, it has offered and sold Securities and will offer and sell
Securities (i) as part of its distribution at any time and (ii) otherwise
until forty days after the later of the date upon which the offering of the
Securities commences and the Closing Time, only in accordance with Rule 903 of
Regulation S or Rule 144A under the 1933 Act.  Accordingly, neither the Initial
Purchasers, their affiliates nor any persons acting on their behalf have
engaged or will engage in any directed selling efforts 
<PAGE>
 
                                     -25-

with respect to Securities, and the Initial Purchasers, their affiliates and any
person acting on their behalf have complied and will comply with the offering
restriction requirements of Regulation S. Each Initial Purchaser agrees that, at
or prior to confirmation of a sale of Securities (other than a sale of
Securities pursuant to Rule 144A), it will have sent to each distributor, dealer
or person receiving a selling concession, fee or other remuneration that
purchases Securities from it or through it during the restricted period a
confirmation or notice to substantially the following effect:

     "The Securities covered hereby have not been registered under
     the United States Securities Act of 1933 (the "Securities Act")
                                                    --------------
     and may not be offered or sold within the United States or to or
     for the account or benefit of U.S. persons (i) as part of their
     distribution at any time and (ii) otherwise until forty days
     after the later of the date upon which the offering of the
     Securities commenced and the date of closing, except in either
     case in accordance with Regulation S or Rule 144A under the
     Securities Act. Terms used above have the meaning given to them
     by Regulation S."

Terms used in the above paragraph have the meanings given to them by Regulation
S.

          Each Initial Purchaser severally represents and agrees that it has not
entered and will not enter into any contractual arrangements with respect to
the distribution of the Securities, except with its affiliates or with the prior
written consent of the Company.

          SECTION 7.  Indemnification.
                      --------------- 

          (a)  The Company agrees to indemnify and hold harmless each Initial
Purchaser and each person, if any, who controls any Initial Purchaser within
the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act as
follows:

               (i)   against any and all loss, liability, claim, damage and
     expense whatsoever, as incurred, arising out of any untrue statement or
     alleged untrue statement of a material fact contained in any Preliminary
     Offering Memorandum or the Final Offering Memorandum (or any amendment or
     supplement thereto), or the omission or alleged omission therefrom of a
     material fact necessary in order to make
<PAGE>
 
                                -26-

     the statements therein, in the light of the circumstances under
     which they were made, not misleading;

               (ii)   against any and all loss, liability, claim, damage and
     expense whatsoever, as incurred, to the extent of the aggregate amount paid
     in settlement of any litigation, or any investigation or proceeding by any
     governmental agency or body, commenced or threatened, or of any claim
     whatsoever based upon any such untrue statement or omission, or any such
     alleged untrue statement or omission; provided, however, that (subject to
     Section 7(d) below) any such settlement is effected with the written
     consent of the Company; and

               (iii)  against any and all expense whatsoever, as incurred
     (including the reasonable fees and disbursements of counsel chosen as
     provided in Section 7(c) below), reasonably incurred in investigating,
     preparing or defending against any litigation, or any investigation or
     proceeding by any governmental agency or body, commenced or threatened, or
     any claim whatsoever based upon any such untrue statement or omission, or
     any such alleged untrue state ment or omission, to the extent that any such
     expense is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss,
liability, claim, damage or expense to the extent arising out of any untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Company by any
Initial Purchaser through Merrill Lynch expressly for use in the Offering
Memorandum (or any amendment or supplement thereto) and provided, further, that
this indemnity agreement shall not inure to the benefit of any Initial Purchaser
from whom the person asserting any such loss, liability, claim, damage or
expense purchased Securities, or any person controlling such Initial Purchaser,
if a copy of the Final Memorandum (or the Final Memorandum as amended or
supplemented) was not sent or given by or on behalf of the Initial Purchasers
(and the Company shall have timely furnished the Initial Purchasers with
sufficient copies thereof) to such person at or prior to the time of delivery of
written confirmation of the sale of the Securities to such person and if the
Final Memorandum (or the Final Memorandum as amended or supplemented) corrected
the untrue statement or omission giving rise to such loss, liability, claim,
damage or expense.
<PAGE>
 
                                -27-

          (b)  Each Initial Purchaser severally agrees to indemnify and hold
harmless the Company, its directors and each person, if any, who controls the
Company within the meaning of Section 15 of the 1933 Act or Section 20 of the
1934 Act against any and all loss, liability, claim, damage and expense
described in the indemnity contained in subsection (a) of this Section 7, as
incurred, but only with respect to untrue statements or omissions, or alleged
untrue statements or omissions, made in the Preliminary Offering Memorandum or
the Final Offering Memorandum (or any amendment or supplement thereto) in
reliance upon and in conformity with written information furnished to the
Company by such Initial Purchaser through Merrill Lynch expressly for use in the
Preliminary Offering Memorandum or the Final Offering Memorandum (or any
amendment or supple ment thereto).

          (c)  Each indemnified party shall give notice as promptly as
reasonably practicable to each indemnifying party of any action commenced
against it in respect of which indemnity may be sought hereunder, but failure
to so notify an indemnifying party shall not relieve such indemnifying party
from any liability hereunder to the extent it is not materially prejudiced as a
result thereof and in any event shall not relieve it from any liability which
it may have otherwise than on account of this indemnity agreement.  In the case
of parties indemnified pursuant to Section 7(a) above, counsel to the 
indemnified parties shall be selected by Merrill Lynch, and, in the case of
parties indemnified pursuant to Section 7(b) above, counsel to the indemnified
parties shall be selected by the Company.  An indemnifying party may participate
at its own expense in the defense of any such action; provided, however, that
counsel to the indemnifying party shall not (except with the consent of the
indemnified party) also be counsel to the indemnified party.  In no event shall
the indemnifying parties be liable for fees and expenses of more than one
counsel (in addition to any local counsel) separate from their own counsel for
all indemnified parties in connection with any one action or separate but
similar or related actions in the same jurisdiction arising out of the same
general allegations or circumstances.  No indemnifying party shall, without the
prior written consent of the indemnified parties, settle or compromise or
consent to the entry of any judgment with respect to any litigation, or any
investigation or proceeding by any governmental agency or body, commenced or
threatened, or any claim whatsoever in respect of which indemnification or
contribution could be sought under this Section 7 or Section 8 hereof (whether
or not the indemnified parties are actual or potential parties thereto), unless
such settlement, compromise or consent (i) in-
<PAGE>
 
                                -28-

cludes an unconditional release of each indemnified party from all liability
arising out of such litigation, investigation, proceeding or claim and (ii) does
not include a statement as to or an admission of fault, culpability or a failure
to act by or on behalf of any indemnified party.

          (d)  If at any time an indemnified party shall have requested an
indemnifying party to reimburse the indemnified party for fees and expenses of
counsel to which such indemnified party is entitled pursuant to Section 7(a) or
(b), such indemnifying party agrees that it shall be liable for any settlement
of the nature contemplated by Section 7(a)(ii) effected without its written
consent if (i) such settlement is entered into more than 45 days after receipt
by such indemnifying party of the aforesaid request, (ii) such indemnifying
party shall have received notice of the terms of such settlement at least 30
days prior to such settlement being entered into and (iii) such indemnifying
party shall not have reimbursed such indemnified party in accordance with such
request prior to the date of such settlement.

          SECTION 8.  Contribution.  If the indemnification provided for in
                      ------------                                         
Section 7 hereof is for any reason unavailable to or insufficient to hold
harmless an indemnified party in respect of any losses, liabilities, claims,
damages or expenses referred to therein, then each indemnifying party shall
contribute to the aggregate amount of such losses, liabilities, claims, damages
and expenses incurred by such indemnified party, as incurred, (i) in such
proportion as is appropriate to reflect the relative benefits received by the
Company on the one hand and the Initial Purchasers on the other hand from the
offering of the Securities pursuant to this Agreement or (ii) if the allocation
provided by clause (i) is not permitted by applicable law, in such proportion as
is appropriate to reflect not only the relative benefits referred to in clause
(i) above but also the relative fault of the Company on the one hand and of the
Initial Purchasers on the other hand in connection with the statements or
omissions which resulted in such losses, liabilities, claims, damages or
expenses, as well as any other relevant equitable considerations.

          The relative benefits received by the Company, on the one hand, and
the Initial Purchasers, on the other hand, in connection with the offering of
the Securities pursuant to this Agreement shall be deemed to be in the same
respective proportions as the total net proceeds from the offering of the
Securities pursuant to this Agreement (before deducting expenses)
<PAGE>
 
                                     -29-

received by the Company, and the total discount received by the Initial
Purchasers, bear to the aggregate initial offering price of the Securities.

          The relative fault of the Company, on the one hand, and the Initial
Purchasers, on the other hand, shall be determined by reference to, among other
things, whether any such untrue or alleged untrue statement of a material fact
or omission or alleged omission to state a material fact relates to information
supplied by the Company or by the Initial Purchasers and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission.

          The Company and the Initial Purchasers agree that it would not be just
and equitable if contribution pursuant to this Section 8 were determined by pro
rata allocation (even if the Initial Purchasers were treated as one entity for
such purpose) or by any other method of allocation which does not take account
of the equitable considerations referred to above in this Section 8. The
aggregate amount of losses, liabilities, claims, damages and expenses incurred
by an indemnified party and referred to above in this Section 8 shall be deemed
to include any legal or other expenses reasonably incurred by such indemnified
party in investigating, preparing or defending against any litigation, or any
investigation or proceeding by any governmental agency or body, commenced or
threatened, or any claim whatsoever based upon any such untrue or alleged 
untrue statement or omission or alleged omission.

          Notwithstanding the provisions of this Section 8, no Initial Purchaser
shall be required to contribute any amount in excess of the amount by which the
total price at which the Securities purchased by it and offered to Subsequent
Purchasers exceeds the amount of any damages which such Initial Purchaser has
otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission.

          No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the 1933 Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation.

          For purposes of this Section 8, each person, if any, who controls an
Initial Purchaser within the meaning of Section 15 of the 1933 Act or Section 20
of the 1934 Act shall have the same rights to contribution as such Initial
Purchaser, and each director of the Company and each person, if any, who
controls
<PAGE>
 
                                     -30-

the Company within the meaning of Section 15 of the 1933 Act or Section 20 of
the 1934 Act shall have the same rights to contribution as the Company. The
Initial Purchasers' respective obligations to contribute pursuant to this
Section 8 are several in proportion to the principal amount of Securities set
forth opposite their respective names in Schedule A hereto and not joint.
                                         ----------                      

          SECTION 9.  Representations, Warranties and Agreements to Survive

Delivery.  All representations, warranties and agreements contained in this
- --------                                                                   
Agreement or in certificates of officers of the Company submitted pursuant
hereto, shall remain operative and in full force and effect, regardless of any
investigation made by or on behalf of any Initial Purchaser or controlling
person, or by or on behalf of the Company, and shall survive delivery of the
Securities to the Initial Purchasers.

          SECTION 10. Termination of Agreement.
                      ------------------------ 

          (a)  Merrill Lynch may terminate this Agreement, by notice to the
Company, at any time at or prior to the Closing Time (i) if there has been,
since the time of execution of this Agreement or since the respective dates as
of which information is given in the Offering Memorandum, any Material Adverse
Change, (ii) if there has occurred any material adverse change in the financial
markets in the United States, any outbreak of hostilities or escalation thereof
or other calamity or crisis or any change or development involving a prospective
change in national or international political, financial or economic
conditions, in each case the effect of which is such as to make it, in the
judgment of Merrill Lynch, impracticable to market the Securities or to enforce
contracts for the sale of the Securities, (iii) if trading in any securities of
the Company has been suspended or limited by the Commission, if trading
generally on the American Stock Exchange or the New York Stock Exchange or in
the Nasdaq National Market System has been suspended or limited, or minimum or
maximum prices for trading have been fixed, or maximum ranges for prices have
been required, by any of said exchanges or by such system or by order of the
Commission, the NASD or any other governmental authority, or (iv) if a banking
moratorium has been declared by either Federal or New York authorities.

          (b)  If this Agreement is terminated pursuant to this Section 10, such
termination shall be without liability of any party to any other party except as
provided in Section 4 hereof, and provided further that Sections 1, 7, 8, 12, 13
and
<PAGE>
 
                                     -31-

14 shall survive such termination and remain in full force and effect.

          SECTION 11.  Default by One of the Initial Purchasers.  If one of the
                       -----------------------------------------                
Initial Purchasers shall fail at the Closing Time to purchase the Securities
which it is obligated to purchase under this Agreement (the "Defaulted

to make arrangements for the non-defaulting Initial Purchaser, or any other
Initial Purchaser, to purchase all, but not less than all, of the Defaulted
Securities in such amounts as may be agreed upon and upon the terms herein set
forth; if, however, Merrill Lynch shall not have completed such arrangements
within such 24-hour period, then this Agreement shall terminate without
liability on the part of the non-defaulting Initial Purchaser.

          No action taken pursuant to this Section 11 shall relieve any
defaulting Initial Purchaser from liability in respect of its default.

          In the event of any such default which does not result in a
termination of this Agreement, either Merrill Lynch or the Company shall have
the right to postpone the Closing Time for a period not exceeding seven days in
order to effect any required changes in the Offering Memorandum or in any other
documents or arrangements.  As used herein, the term "Initial Purchaser"

their heirs and legal representatives, any legal or equitable right, remedy or
claim under or in respect of this Agreement or any provision herein contained.

existing as a corporation in good standing under the laws of the jurisdiction of
its incorporation, has corporate power and authority to own, lease and operate

          (vii)  The Indenture has been duly authorized, executed and delivered
by the Company and (assuming the due authorization, execution and delivery
thereof by the Trustee) constitutes a valid and binding agreement of the
Company, enforceable against the Company in accordance with its terms, except
as the enforcement thereof may be limited by bankruptcy, insolvency (including,
without limitation, all laws relating to fraudulent transfers), reorganization,
moratorium or other similar laws relating to or affecting enforcement of
creditors' rights generally, or by general principles of equity (regardless of
whether enforcement is considered in a proceeding in equity or at law).

          (viii) The Registration Rights Agreement has been duly authorized,
executed and delivered by the Company and (assuming the due authorization,
execution and delivery thereof by the Initial Purchasers) constitutes a valid
and binding agreement of the Company, enforceable against the Company in
accordance with its terms, except (i) as the enforcement thereof may be limited
by bankruptcy, insolvency (including, without limitation, all laws relating to

indemnification and contribution thereunder may be limited by federal or state
securities laws or regulations or the public policy underlying such laws or
regulations.

          (ix)   The Securities are in the form contemplated by the Indenture,
have been duly authorized by the Company and, when executed by the Company and
authenticated by the Trustee in the manner provided in the Indenture (assuming
the due authorization, execution and delivery of the Indenture by the Trustee)
and delivered against payment of the purchase price therefor, will constitute
valid and binding obligations of the Company entitled to the benefits of the
Indenture, enforceable against the Company in accordance with their terms,
except as the enforcement thereof may be limited by bankruptcy, insolvency
(including, without limitation, all laws relating to fraudulent transfers),
reorganization, moratorium or other similar laws relating to or affecting
enforcement of creditors' rights generally, or by general principles of equity
(regardless of whether enforcement is considered in a proceeding in equity or
at law).

          (x)    The Exchange Securities and the Private Exchange Securities
have been duly authorized by the Company and, when executed by the Company and
authenticated in the manner provided for in the Indenture and delivered in
exchange for the Securities in accordance with the terms of the Registration

the benefits of the Indenture, except as the enforcement thereof may be limited
by bankruptcy, insolvency (including, without limitation, all laws relating to
fraudulent transfers), reorganization, moratorium or other similar laws relating
to or affecting enforcement of creditors' rights generally, or by general
principles of equity (regardless of whether enforcement is considered in a
proceeding in equity or at law).

          (xi)   The Securities, the Indenture and the Registration Rights
Agreement conform in all material respects to the descriptions thereof contained
in the Offering Memorandum.

          (xii)  The execution, delivery and performance of each of the
Operative Documents and the consummation of the transactions contemplated
thereby (including the issuance and sale of the Securities and the use of the
proceeds therefrom as described in the Offering Memorandum under the caption
"Use Of Proceeds") and compliance by the Company with its obligations thereunder
will not, whether with or without the giving of notice or lapse of time or
both, conflict with or constitute a breach of, or default or Repayment Event (as
defined in Section l(a)(xvi) of the Purchase Agreement) under, or a violation
of, or result in the creation or imposition of any lien, charge or encumbrance
upon any property or assets of the Company or any Subsidiary pursuant to, (i)
any contract, indenture, mortgage, deed of trust, loan or credit agreement,
note, lease or any other agreement or instrument, known to us, to which the
Company or any of the Subsidiaries is a party or by which it or any of them may
be bound, or to which any of the property or assets of the Company or any
Subsidiary is subject, (ii) the charter or bylaws of the Company or any of the
Subsidiaries, or (iii) any applicable law, statute, rule or regulation of the
United States, the State of New York or the State of Delaware, or any judgment,
order, writ or decree, known to us, of any government, government
instrumentality or court, domestic or foreign, having jurisdiction over the
Company or any of the Subsidiaries or any of their respective properties or
assets.

          (xiii) No filing with, or authorization, approval, consent, license,
order, registration, qualification or decree

                                      A-3

of, any court or governmental authority or agency is necessary or required in
connection with the offering, issuance or sale of the Securities, the Exchange
Securities or the Private Exchange Securities, the performance by the Company
of its obligations under the Operative Documents or the consummation of the
transactions contemplated thereby, except as may be required under the 1933
Act, under the 1939 Act or pursuant to state securities or "blue sky" laws, as
to which no opinion is rendered hereby.

          (xiv)    To the best of our knowledge, there is no pending or 
threatened action, suit, proceeding, inquiry or investigation (collectively,
"Legal Proceedings"), to which the Company or any Subsidiary is a party, or to
- -------------------
which the property of the Company or any Subsidiary is subject, before or by any
court or governmental agency or body, which might reasonably be expected to
result in a Material Adverse Effect, or which might reasonably be expected to
materially and adversely affect the properties or assets of the Company or any
Subsidiary or the consummation of the Purchase Agreement by the Company or its
obligations thereunder or the transactions contemplated by the Offering
Memorandum.

          (xv)     The information in the Offering Memorandum under the headings
"Business--Regulatory and Environmental Matters" and "Business--Product
Liability and Legal Proceedings," to the extent that it constitutes summaries of
legal matters, legal proceedings or legal conclusions, fairly summarizes such
matters in all material respects.

          (xvi)    All descriptions in the Offering Memorandum of contracts and
other documents to which the Company or any of the Subsidiaries is a party are
accurate in all material respects.

          (xvii)   To the best of our knowledge, there are no franchises,
contracts, indentures, mortgages, loan agreements, notes, leases or other
instruments that would be required to be described in a registration statement
on Form S-1 under the 1933 Act that are not described or referred to in the
Offering Memorandum.

          (xviii)  Assuming compliance by the Initial Purchasers with the
representations and warranties in Section 2(c) of the Purchase Agreement and the
procedures set forth in Section 6 of the Purchase Agreement, it is not necessary
in connection with the offer, sale and delivery of the Securities to the Initial
Purchasers and to each Subsequent Purchaser in the manner con-

                                      A-4
<PAGE>
 
templated by the Purchase Agreement and the Offering Memorandum to register the
Securities under the 1933 Act or to qualify the Indenture under the 1939 Act.

          (xix)  The Company is not an "investment company" or an entity
"controlled" by an "investment company," as such terms are defined in the 1940
Act.
  
          (xx)   Neither the consummation of the transactions contemplated
hereby nor the sale, issuance, execution or delivery of the Securities, nor the
application of the proceeds therefrom (if applied as described in the Offering
Memorandum under the caption "Use of Proceeds"), will violate Regulation G, T, U
or X of the Board of Governors of the Federal Reserve System.

          We have participated in conferences with officers and other
representatives of the Company, your representatives and representatives of the
independent accountants for the Company at which conferences the contents of the
Offering Memorandum and related matters were discussed.  However, we do not
express an opinion with respect to, and do not assume any responsibility for,
the accuracy, completeness or fairness of the statements contained in the
Offering Memorandum or make any representation that we have independently
verified or checked the accuracy, completeness or fairness of such statements.
On the basis of and subject to the foregoing, we advise you that nothing has
come to our attention that has led us to believe that the Final Offering
Memorandum, as of its date or as of the date hereof, included or includes an
untrue statement of a material fact or omitted or omits to state a material fact
necessary in order to make the statements therein, in the light of the 
circumstances under which they were made, not misleading (it being understood
that we express no belief with respect to the financial statements, including
the notes thereto, or any other financial or statistical data set forth or
referred to in the Offering Memorandum).

          In rendering such opinion, such counsel may rely, as to matters of
fact (but not as to legal conclusions), to the extent they deem proper, on
certificates of responsible officers of the Company and public officials.  Such
opinion shall not state that it is to be governed or qualified by, or that it is
otherwise subject to, any treatise, written policy or other document relating to
legal opinions, including, without limitation, the Legal Opinion Accord of the
ABA Section of Business Law (1991).

                             AMENDED AND RESTATED
                         CERTIFICATE OF INCORPORATION
                                      OF
                              THE GSI GROUP, INC.

                                                        

     This Amended and Restated Certificate of Incorporation, having been duly
adopted in accordance with the provisions of Section 245 of the General
Corporation Law of the State of Delaware amends and restates in its entirety the
certificate of incorporation of The GSI Group, Inc., which was originally
incorporated on April 30, 1964 as Sloan Implement Company, Inc.:

     FIRST: The name of the corporation (hereinafter called the "Corporation")
is:

                              The GSI Group, Inc.

     SECOND: The address, including street, number, city and county of the
registered office of the Corporation in the State of Delaware is 1013 Centre
Road, Wilmington, Delaware in the County of New Castle and the name of the
stock, $.01 par value, 1,100,000 shall be non-voting stock, $.01 par value, and
100,000 shall be preferred stock, $.01 par value. Shares of preferred stock will
be issued, from time to time, in one or more series, as authorized by the Board
of Directors of the Corporation (the "Board"). Prior to the issuance of shares
of each series, the Board by resolution shall (i) designate that series to
distinguish it from all other series and classes of stock of the Corporation;
(ii) specify the number of shares to be included in the series and shall set the
terms, preferences, conversion or other rights, voting powers, restrictions,
limitations as to dividends or other distributions, qualifications and terms or
conditions of redemption. Subject to the express terms of any other series of
preferred stock outstanding at the time and notwithstanding any other provisions
of these ARTICLES, the Board may increase or decrease the number of shares of,
or alter the designations, classify or reclassify, any unissued shares of any
series of preferred stock by setting or changing, in any one or more respects,
from time to time before issuing the shares, the terms, preferences, conversion
or other rights, voting powers, restrictions, limitations as to dividends or
other distributions, qualifications or terms or conditions of redemption of the
shares of any series of preferred stock. Any and all such shares issued, and for
which the full consideration has been paid or delivered, shall be deemed fully
paid stock and the holder of such shares shall not be liable for any further
call or assessment or any other payment thereon.

     FIFTH:  The books of the Corporation may be kept (subject to any provision
contained in the statutes) outside the State of Delaware at such place or places
as may be designated from time to time by the Board or in the By-Laws of the
Corporation.

<PAGE>
 
     SIXTH: Whenever a compromise or arrangement is proposed between this
Corporation and its creditors or any class of them and/or between this
Corporation and its stockholders or any class of them, any court of equitable
jurisdiction within the State of Delaware may, on the application in a summary
way of this Corporation or of any creditor or stockholder thereof or on the
application of any receiver or receivers appointed for this Corporation under
the provisions of Section 291 of Title 8 of the Delaware Code or on the
application of trustees in dissolution or of any receiver or receivers appointed
for this Corporation under the provisions of Section 292 of Title 8 of the
Delaware Code order a meeting of the creditors or class of creditors, and/or of
the stockholders or class of stockholders of this Corporation, as the case may
be, to be summoned in such manner as the said court directs. If a majority in
number representing three-fourths in value of the creditors or class of
creditors, and/or of the stockholders or class of stockholders of this
Corporation, as the case may be, agree to any compromise or arrangement and to
any reorganization of this Corporation as a consequence of such compromise or
arrangement, the said compromise or arrangement and the said reorganization
shall, if sanctioned by the court to which the said application has been made,
be binding on all the creditors or class of creditors, and/or of the
stockholders or class of stockholders of this Corporation as the case may be,
and also on this Corporation.

     SEVENTH: For the management of the business and for the conduct of the
affairs of the Corporation and in further definition, limitation and regulation
of the powers of the Corporation and of its directors and stockholders, it is
further provided:

     The number of directors of the Corporation shall be as specified in the By-
     Laws of the Corporation but such number may from time to time be increased
     or decreased in such manner as may be prescribed by the By-Laws. In no
     event shall the number of directors be less than the minimum prescribed by
     law. The election of directors need not be by ballot, unless the By-Laws of
     the Corporation so provide. Directors need not be stockholders.

     In furtherance and not in limitation of the powers conferred by the laws of
     the State of Delaware, the Board is expressly authorized and empowered to
     make, alter, amend, and repeal By-Laws, subject to the power of the
     stockholders to alter or repeal By-Laws made by the Board.

     Any director or any officer elected or appointed by the stockholders or by
     the Board may be removed at any time in such manner as shall be provided in
     the By-Laws of the Corporation.

     In the absence of fraud, no contract or other transaction between the
     Corporation and any other corporation and no act of the Corporation, shall
     in any way be affected or invalidated by the fact that any of the directors
     of the Corporation are pecuniarily or otherwise interested in, or are
     directors or officers of, such other Corporation; and in the absence of
     fraud, any director, individually, or any firm of which any director may be
     a member, may be a party to, or may be pecuniarily or otherwise interested
     in, any contract or transaction of the Corporation; provided, in any case,
     that the fact that he or such firm

                                       2
<PAGE>
 
     is so interested shall be disclosed or shall have been known to the Board
     or the majority thereof; and any director of the Corporation, who is also a
     director or officer of any such other Corporation, or who is also
     interested, may be counted in determining the existence of a quorum at any
     meeting of the Board of the Corporation which shall authorize any such
     contract, act or transaction, and may vote thereat to authorize any such
     contract, act or transaction, with like force and effect as if he were not
     such director or officer of such other corporation, or not so interested.

     To the fullest extent permitted by the Delaware General Corporation Law as
     it now exists or may hereafter be amended, no director of this Corporation
     shall be liable to this Corporation or any of its stockholders for monetary
     damages for breach of fiduciary duty as a director. If the General
     Corporation Law of the State of Delaware is amended to authorize the
     further elimination of liability of directors, then the liability of a
     director of the Corporation, in addition to the limitation on personal
     liability for breach of fiduciary duty shall be limited to the furthest
     extent permitted by an amended General Corporation Law of the State of
     Delaware. Any repeal or modification of this Article SEVENTH by the
     stockholders of the Corporation shall be prospective only, and shall not
     adversely affect any limitation on the personal liability of as director of
     the Corporation existing at the time of such repeal or modification.

     EIGHTH: (a) The Corporation shall have power to indemnify any person who
was or is a party or is threatened to be made a party to any threatened, pending
or completed action, suit or proceeding, whether civil, criminal, administrative
or investigative (other than an action by or in the right of the Corporation) by
reason of the fact that he is or was a director, officer, employee or agent of
the Corporation, or is or was serving at the request of the Corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against expenses (including attorneys'
fees), judgments, fines, and amounts paid in settlement actually and reasonably
incurred by him in connection with such action, suit or proceeding if he acted
in good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the Corporation and, with respect to any criminal action
or proceeding, had no reasonable cause to believe his conduct was unlawful. The
termination of any action, suit or proceeding by judgment, order, settlement,
conviction, or upon a plea of nolo contendere or its equivalent, shall not, of
itself, create a presumption that the person did not act in good faith and in a
manner which he reasonably believed to be in or not opposed to the best
interests of the Corporation, and with respect to any criminal action or
proceeding, had reasonable cause to believe that his conduct was unlawful.

          The Corporation shall have power to indemnify any person who was or is
a party or is threatened to be made a party to any threatened, pending or
completed action or suit by or in the right of the Corporation to procure a
judgment in its favor by reason of the fact that he is or was a director,
officer, employee or agent of the Corporation, or is or was serving at the
request of the Corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise against
expenses (including attorneys' fees) actually and reasonably incurred by him in
connection with the defense or settlement of such action or suit if he acted in
good faith and in a manner he reasonably believed to be in or not

                                       3
<PAGE>
 
opposed to the best interests of the Corporation and except that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the Corporation
unless and only to the extent that the Court of Chancery or the court in which
such action or suit was brought shall determine upon application that, despite
the adjudication of liability but in view of all the circumstances of the case,
such person is fairly and reasonably entitled in indemnity for such expenses
which the Court of Chancery or such other court shall deem proper.

          To the extent that a director, officer, employee or agent of the
Corporation has been successful on the merits or otherwise in defense of any
action, suit or proceeding referred to under Paragraphs (a) and (b) of this
Article, or in defense of any claim, issue or matter therein, he shall be
indemnified against expenses (including attorneys' fees) actually and reasonably
incurred by him in connection therewith.

          Any indemnification under paragraphs (a) and (b) (unless ordered by a
court) shall be made by the Corporation only as authorized in the specific case
upon a determination that indemnification of the director, officer, employee or
agent is proper in the circumstances because he has met the applicable standard
of conduct set forth in paragraphs (a) and (b). Such determination shall be made
(1) by the board of directors by a majority vote of a quorum consisting of
directors who were not parties to such action, suit or proceeding, or by a
majority vote of a committee of such directors, or (2) if such a quorum is not
obtainable or, even if obtainable, a quorum of disinterested directors so
directs, by independent legal counsel in a written opinion, or (3) by the
stockholders.

          Expenses incurred in defending a civil or criminal action, suit, or
proceeding may be paid by the Corporation in advance of the final disposition of
such action, suit or proceeding upon receipt of an undertaking by or on behalf
of the director, officer, employee or agent to repay such amount if it shall
ultimately be determined that he is not entitled to be indemnified by the
Corporation as authorized in this Article EIGHTH.

          The indemnification and advancement of expenses provided by or granted
pursuant to the other sections of this Article EIGHTH shall not be deemed
exclusive of any other rights to which those seeking indemnification or
advancement of expenses may be entitled under any by-law, agreement, vote of
stockholders or disinterested directors or otherwise, both as to action in his
official capacity and as to action in another capacity while holding such
office.

          The Corporation shall have power to purchase and maintain insurance on
behalf of any person who is or was a director, officer, employee or agent of the
Corporation, or is or was serving at the request of the Corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise against any liability asserted against him
and incurred by him in any such capacity, or arising out of his status as such,
whether or not the Corporation would have the power to indemnify him against
such liability under the provisions of this Article EIGHTH.

          For the purposes of this Article EIGHTH, reference to "the
Corporation" shall include, in addition to the resulting corporation, any
constituent corporation (including any

                                       4
<PAGE>
 
constituent of a constituent) absorbed in a consolidation or merger which, if
its separate existence had continued, would have had power and authority to
indemnify its directors, officers and employees or agents, so that any person
who is or was serving at the request of such constituent corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise shall stand in the same position under the
provisions of this section with respect to the resulting or surviving
corporation as he would have with respect to such constituent corporation if its
separate existence had continued.

            For the purposes of this Article EIGHTH, references to "other
enterprises" shall include employee benefit plans; references to "fines" shall
include any excise taxes assessed on a person with respect to any employee
benefit plan; and references to "serving at the request of the Corporation"
shall include any service as a director, officer, employee or agent of the
Corporation which imposes duties on, or involves services by, such director,
officer employee, or agent with respect to an employee benefit plan, its
participants or beneficiaries; and a person who acted in good faith and in a
manner he reasonably believed to be in the interest of the participants and
beneficiaries of an employee benefit plan shall be deemed to have acted in a
manner "not opposed to the best interests of the Corporation" as referred to in
this Article EIGHTH.

            The indemnification and advancement of expenses provided by, or
granted pursuant to, this Article EIGHTH shall, unless otherwise provided when
authorized or ratified, continue as to a person who has ceased to be a director,
officer, employee or agent and shall inure to the benefit of the heirs,
executors and administrators of such a person.

such provision, as the Board of Directors of such corporation may determine.

     Shares standing in the name of a deceased person may be voted by his
administrator or executor, either in person or by proxy. Shares standing in the
name of a guardian, conservator or trustee may be voted by such fiduciary,

entitled, as such fiduciary, to vote shares held by him without a transfer of
such shares into his name.

     Shares standing in the name of a receiver may be voted by such receiver,
and shares held by or under the control of a receiver may be voted by such
receiver without the transfer thereof into his name if authority so to do be
contained in an appropriate order of the court by which such receiver was
appointed.

members thereof present at any meeting and not disqualified from voting, whether
or not he or they constitute a quorum, may unanimously appoint another member of

Certificate of Incorporation by the Board of Directors, adopting an agreement of
merger or consolidation, recommending to the stockholders the sale, lease or
exchange of all or substantially all of the Corporation's property and assets,
recommending to the stockholders a dissolution of the Corporation or a
revocation of a dissolution, or amending the By-Laws of the Corporation; and,

Certificate of Incorporation, no director shall be personally liable to the
Corporation or any stockholder for monetary damages for breach of fiduciary duty
as a director; provided, however, that the foregoing provision shall not
eliminate or limit the liability of a director (i) for any breach of the
director's duty of loyalty to the Corporation or its stockholders, (ii) for acts
or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) under Section 174 of Title 8 of the Delaware
Code (relating to the Delaware General Corporation Law) or any amendment thereto
or successor provision thereto, or (iv) for any transaction from which the
director derived an improper personal benefit. Neither the amendment nor the
repeal of this provision in the Corporation's Certificate of Incorporation, nor
the adoption of any provision to the Certificate of Incorporation inconsistent
with this provision, shall eliminate or reduce the effect of this provision in
respect of any matter occurring, or any cause of action, suit or claim that, but
for this provision, would accrue or arise, prior to such amendment, repeal or
adoption of an inconsistent provision. If the Delaware General Corporation Law
is amended to authorize the further elimination of liability of directors, then
the liability of a director of the Corporation, in addition to the limitation on
personal liability for breach of fiduciary duty shall be limited to the furthest
extent permitted by an amended Delaware General Corporation Law. Any repeal or
modification of this Article 3 by the stockholders of the Corporation shall be
prospective only, and shall not adversely affect any limitation on the

     5.1.  ACTIONS AGAINST A PERSON. The Corporation shall indemnify any person
           ------------------------   
who was or is a party or is threatened to be made a party to any threatened,

Corporation) by reason of the fact that he is or was a director, officer,
employee or agent of the Corporation, or is or was serving at the request of the
Corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, against expenses

actually and reasonably incurred by him in connection with such action, suit or
proceeding if he acted in good faith and in a manner he reasonably believed to
be in or not opposed to the best interests of the Corporation, and with respect
to any criminal action or proceeding, had no reasonable cause to believe his
conduct was unlawful. The termination of any action, suit or proceeding by
judgment, order, settlement, conviction, or upon a plea of nolo contendre or its
equivalent, shall not, of itself, create a presumption that the person did not
act in good faith and in a manner which he reasonably believed to be in or not
opposed to the best interests of the Corporation, and, with respect to any
criminal action or proceeding, had reasonable cause to believe that his conduct
was unlawful.

     5.2.  ACTIONS BY OR IN THE RIGHT OF THE CORPORATION.  The Corporation shall
           ---------------------------------------------                        
indemnify any person who was or is a party or is threatened to be made a party

Corporation to procure a judgment in its favor by reason of the fact that he is
or was a director, officer, employee or agent of the Corporation, or is or was
serving at the request of the Corporation as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise against expenses (including attorneys' fees) actually and reasonably
incurred by him in connection with the defense or settlement of such action or
suit if he acted in good faith and in a manner he reasonably believed to be in
or not opposed to the best interests of the Corporation and except that no
indemnification shall be made in respect of any claim, issue or matter as to

which such person shall have been adjudged to be liable to the Corporation
unless and only to the extent that the Court of Chancery or the court in which
such action or suit was brought shall determine upon application that, despite

such person is fairly and reasonably entitled to indemnity for such expenses
which the Court of Chancery or such other court shall deem proper.

     5.3.  INDEMNIFICATION IN EVENT OF SUCCESSFUL DEFENSE.  To the extent that a

therein, he shall be indemnified against expenses (including attorneys' fees)
actually and reasonably incurred by him in connection therewith.

     5.4.  BOARD OF DIRECTORS' APPROVAL. Any indemnification under Sections 5.1
           ----------------------------        
and 5.2 of these By-Laws (unless ordered by a court) shall be made by the
Corporation only as authorized in the specific case upon a determination that
indemnification of the director, officer, employee or agent is proper in the
circumstances because he has met the applicable standard of conduct set forth in
Sections 5.1 and 5.2 hereof. Such determination shall be made (1) by the Board
of Directors by a majority vote of a quorum consisting of directors who were not
parties to such action, suit or proceeding, or (2) if such a quorum is not
obtainable, or, even if obtainable but a quorum of disinterested directors so
directs, by independent legal counsel in a written opinion, or (3) by the
stockholders.

     5.5.  ADVANCE INDEMNITY PAYMENTS. Expenses incurred in defending a civil or
           --------------------------       
criminal action, suit or proceeding may be paid by the Corporation in advance of
the final disposition of such action, suit or proceeding upon receipt of an
undertaking by or on behalf of the director, officer, employee or agent to repay
such amount if it shall ultimately be determined that he is not entitled to be
indemnified by the Corporation as authorized in this Article.

     5.6.  NON-EXCLUSIVITY. The indemnification and advancement of expenses
           ---------------  
provided by or granted pursuant to, Article NINTH of the Corporation's
Certificate of Incorporation, the Delaware General Corporation Law and this
Article shall not be deemed exclusive of any other rights to which those seeking
indemnification or advancement of expenses may be entitled under any By-Law,
agreement, vote of stockholders or disinterested directors or otherwise, both as
to action in his official capacity and as to action in another capacity while
holding such office.

     5.7.  INDEMNITY INSURANCE. The Corporation may purchase and maintain
           -------------------     
insurance on behalf of any person who is or was a director, officer, employee or
agent of the Corporation, or is or was serving at the request of the Corporation
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise against any liability asserted against
him and incurred by him in any such capacity, or arising out of his status as

merger which, if its separate existence had continued, would have had the power
and authority to indemnify its directors, officers and employees or agents, so

corporation as a director, officer, employee or agent of another corporation or
is or was serving at the request of such constituent corporation as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust or other enterprise, shall stand in the same position under the provisions
of this Article with respect to the resulting or surviving corporation as he

          herein for any annual meeting of the shareholders, or at any
          adjournment thereof, the Board of Directors shall cause the election
          to be held at a special meeting of the shareholders as soon thereafter
          as conveniently may be.

Section 2.  Special Meetings. Special meetings of the shareholders, for any
          purpose or purposes, unless otherwise prescribed by statute, may be
          called by the President or by the Board of Directors, and shall be

          to vote at the meeting.

          for any special meeting called by the Board of Directors. A waiver of
          notice signed by all shareholders entitled to vote at a meeting may
          designate any place, either within or without the State of Iowa, as
          the place for holding of such meeting. If no designation is made, or
          if a special meeting be otherwise called, the place of meeting shall
          be the registered office of the corporation in the State of Iowa.

Section 4.  Notice of Meeting.  Written or printed notice stating the
          place, day and hour of the meeting and, in case of a special meeting,
          the purpose or purposes for which the meeting is called, shall be
          delivered not less than 10 nor more than 60 days before the date of
          the meeting, either personally or by mail, by or at the direction of
          the President, the Secretary, or the officer or persons calling the
          meeting, to each shareholder of record entitled to vote at such
          meeting. If mailed, such notice shall be deemed to be delivered when
          deposited in the United States mail, addressed to the shareholder at
          his address as it appears on the stock transfer books of the
          corporation, with postage thereon prepaid.

Section 5.  Closing of Transfer Books or Fixing of Record Date. For the
          purpose of determining shareholders entitled to notice of, or to vote
          at any special meeting of shareholders or any adjournment thereof, or
          shareholders entitled to receive payment of any dividend, or in order
          to make a determination of shareholders for any other proper purpose,
          the Board of Directors of the corporation may provide that the stock
          transfer books shall be closed for a stated period but not to exceed,
          in any case, 60 days. If the stock transfer books shall be closed for
          the purpose of determining shareholders entitled to notice of or to
          vote at a meeting of shareholders, such books shall be closed for at
          least 10 days immediately preceding such meeting. In lieu of closing
          the stock transfer books, the Board of Directors may fix in advance a
          date as the record date for any such determination of shareholders,
          such date in any case to be not more than 60 days and, in case of a
          meeting of shareholders, not less than 10 days prior to the date on
          which the particular action, requiring such determination of
          shareholders, is to be taken. If the stock transfer books are not
          closed and no record date is fixed for the determination of
          shareholders entitled to notice of or to vote at a meeting of
          shareholders, or shareholders entitled to receive payment of a
          dividend, the date on which notice of the meeting is mailed or the
          date on which the resolution of the Board of Directors declaring such
          dividend is adopted, as the case may be, shall be the record date for
          such determination of shareholders. When a determination of
          shareholders entitled to vote at any meeting of shareholders has been
          made as provided in this section, such determination shall apply to
          any adjournment thereof.

Section 6.  Voting Lists. The officer or agent having charge of the stock
          transfer books for shares of the corporation shall make a complete
          list of the shareholders entitled to vote at such meeting, or any
          adjournment thereof, arranged in alphabetical order, with the address
          of and the number of shares held by each. The list shall be available
          for inspection by any shareholder beginning two business days after
          notice of the meeting is given. The list shall be kept on file at the
          corporation's principal office and shall be subject to inspection by
          any shareholder at any time during usual business hours. Such list
          shall also be produced and kept open at the time and place of the
          meeting and shall be subject to the inspection of any shareholder
          during the whole time of the meeting. The original stock transfer book
          shall be prima facie evidence as to who are the shareholders entitled
          to examine such list or transfer books or to vote at any meeting of
          shareholders.

Section 7.  Quorum. A majority of the outstanding shares of the corporation
          entitled to vote, represented in person or by proxy, shall constitute
          a quorum at a meeting of shareholders. If less than a majority of
          the outstanding shares are represented at a meeting, a majority of the
          shares so represented may adjourn the meeting from time to time
          without further notice. At such adjourned meeting at which a quorum
          shall be present or represented, any business may be transacted which
          might have been transacted at the meeting as originally notified. The
          shareholders present at a duly organized meeting may continue to
          transact business until adjournment, notwithstanding the withdrawal of
          enough shareholders to leave less than a quorum.

Section 8.  Proxy. At all meetings of shareholders, a shareholder may vote by
          proxy by executing in writing an appointment form which specifically
          identifies the proxy and describes the grant of authority to vote.
          Such appointment form shall be filed with the Secretary of the
          corporation before or at the time of the meeting. No appointment form
          shall be valid after 11 months from the date of its execution unless
          otherwise provided in the appointment form.

Section 9.  Voting of Shares. Each outstanding share entitled to vote shall be
          entitled to one vote upon each matter submitted to a vote at a meeting
          of shareholders.

Section 10.  Informal Action by Shareholders. Any action required to be taken at
          a meeting of the shareholders, or any other action which may be taken
          at a meeting of the shareholders, may be taken without a meeting or
          vote as prescribed in the Iowa Business Corporation Act.

          for that purpose by a vote of the holders of a majority of the shares
          then entitled to vote at an election of Directors. Only a shareholder
          may be a Director.

Section 3.  Regular Meetings. A regular meeting of the Board of Directors shall
          be held without other notice than this Bylaw immediately after, and at
          the same place as, the annual meeting of shareholders. The Board of
          Directors may provide, by resolution, the time and place, either

          regular meetings without other notice than such resolution.

Section 4.  Special Meetings. Special meetings of the Board of Directors may be
          called by or at the request of the President or any Director. The

          Iowa, as the place for holding any special meeting of the Board of
          Directors called by them.

Section 5.  Notice. Notice of any special meeting shall be given at least two
          days prior thereto by written notice delivered personally or mailed to

          notice shall be deemed to be delivered when deposited in the United
          States mail, so addressed, with postage thereon prepaid. If notice be
          given by telegram, such notice shall be deemed to be delivered when
          the telegram is delivered to the telegraph company. Any Director may
          waive notice of any meeting. The attendance of a Director at a meeting
          shall constitute a waiver of notice of such meeting, except where a
          Director attends a meeting for the express purpose of objecting to the
          transactions of any business because the meeting is not lawfully
          called or convened. Neither the business to be transacted at, nor the
          purpose of, any regular or special meeting of the Board of Directors
          need be specified in the notice or waiver of notice of such meeting.

          meeting of the Board of Directors or of a committee designated by the
          Board if he participates in such meeting by conference telephone or
          similar communications equipment by means of which all persons
          participating in the meeting can hear each other.

Section 9.  Vacancies. Any vacancy occurring in the Board of Directors and any
          directorship to be filled by reason of an increase in the number of

          Directors then in office, even if less than a quorum of the Board of
          Directors. A Director so elected shall be elected for the unexpired
          term of his predecessor in office or the full term of such new

          Director or a fixed sum for attendance at each meeting of the Board of
          Directors or both. No such payment shall preclude any Director from
          serving the corporation in any other capacity and receiving

          at a meeting of the Board of Directors at which action on any
          corporate matter is taken shall be presumed to have assented to the
          action taken unless his dissent shall be entered in the minutes of the
          meeting or unless he shall file his written dissent to such action
          with the person acting as the Secretary of the meeting before the
          adjournment thereof or shall forward such dissent by registered or
          certified mail to the Secretary of the corporation immediately after
          the adjournment of the meeting. Such right to dissent shall not apply
          to a Director who voted in favor of such action.

aggregate amount of Consolidated Cash Flow Available for Fixed Charges of the

Consolidated Fixed Charge Coverage Ratio for which consolidated financial
information of the Company is internally available (such four full fiscal
quarter period being referred to herein as the "Four Quarter Period") to the
aggregate amount of Consolidated Fixed Charges of the Company for such Four
Quarter Period. For purposes of this definition, "Consolidated Cash Flow

calculated, without duplication, after giving effect on a pro forma basis for
the period of such calculation to (i) the incurrence of any Indebtedness of the

the numerator) of this definition of "Consolidated Fixed Charge Coverage Ratio,"
(1) interest on Indebtedness determined on a fluctuating basis as of the
Transaction Date and which will continue to be so determined thereafter will be
deemed to accrue at a fixed rate per annum equal to the rate of interest on such
Indebtedness in effect on the Transaction Date; (2) if interest on any
Indebtedness actually incurred on the Transaction Date may optionally be
determined at an interest rate based upon a factor of a prime or similar rate, a
eurocurrency interbank offered rate, or other rates, then the interest rate in
effect on the Transaction Date shall be deemed to have been in effect during the
Reference Period; and (3) notwithstanding clause (1) above, interest on
Indebtedness determined on a fluctuating basis, to the extent such interest is
covered by

guaranteed Indebtedness.

Holder of such Depositary receipt; provided, however, that (except as required
                                   --------  -------                          
by law) such custodian is not authorized to make any deduction from the amount
payable to the Holder of such Depositary receipt from any amount received by the

of principal of or interest on the U.S. Government Obligation evidenced by such

          Section 1.04.  Form of Documents Delivered to Trustee.
                         --------------------------------------  

          Upon any request or application by the Company to the Trustee to take
any action under this Indenture, the Company shall furnish to the Trustee (a) an
Officers' Certificate in form and substance reasonably satisfactory to the
Trustee stating that, in the opinion of the signers, all conditions precedent
(including any covenants compliance with which constitutes a condition
precedent), if any, provided for in this Indenture relating to the proposed
action have been complied with, (b) an Opinion of Counsel in form and substance
reasonably satisfactory to the Trustee stating that, in the opinion of counsel,
all such conditions (including any covenants compliance with which constitutes a
condition precedent), have been complied with and (c) where applicable, a
certificate or opinion by an accountant that complies with Section 314(c) of the
Trust Indenture Act.

          Each Officers' Certificate and Opinion of Counsel with respect to
compliance with a condition or covenant provided for in this Indenture shall
include:

          (a)  a statement that the Person making such certificate or Opinion of
Counsel has read such covenant or condition;

          (b)  a brief statement as to the nature and scope of the examination
or investigation upon which the statements contained in such Officers'
Certificate or Opinion of Counsel are based;

          (c)  a statement that, in the opinion of such Person, he has made such
examination or investigation as is necessary to enable him to express an
informed opinion as to whether or not such covenant or condition has been
complied with; and

          (d)  a statement as to whether or not, in the opinion of such Person,
such condition or covenant has been complied with.

          In any case where several matters are required to be certified by, or
covered by an opinion of, any specified Person, it is not necessary that all
such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.
<PAGE>
 
                                     -18-

          Any certificate or opinion of an Officer of the Company may be based,
insofar as it relates to legal matters, upon a certificate or opinion of, or
representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which his certificate or opinion is based are
erroneous.  Any such certificate or opinion of counsel may be based, insofar as
it relates to factual matters, upon a certificate or opinion of, or
representations by, an officer or officers of the Company stating that the
information with respect to such factual matters is in the possession of the
Company, unless such counsel knows, or in the exercise of reasonable care should
know, that the certificate or opinion or representations with respect to such
matters are erroneous.  Opinions of Counsel required to be delivered to the
Trustee may have qualifications customary for opinions of the type required and
counsel delivering such Opinions of Counsel may rely on certificates of the
Company or government of other officials customary for opinions of the type
required, including certificates certifying as to matters of fact, including
that various financial covenants have been complied with.

          Any certificate of opinion of an officer of the Company, and Guarantor
of other obligor on the Notes may be based, insofar as it relates to accounting
matters, upon a certificate or opinion of, or representations by, an accountant
or firm of accountants in the employ of the Company, unless such officer knows,
or in the exercise of reasonable care should know, that the certificate or
opinion or representations with respect to accounting matters upon which his
certificate or opinion may be based are erroneous.  Any certificate or opinion
of any independent firm of public accountants filed with the Trustee shall
contain a statement that such firm is independent with respect to the Company.

          Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated, with
proper identification of each matter covered therein, and form one instrument.

          Section 1.05.  Acts of Holders.
                         --------------- 

          (a)  Any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Indenture to be given or taken by
Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in Person or by an agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required, to the Company.  Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
                                                  ---                        
such instrument or instruments.  Proof of execution (as provided below in
subsection (b) of this Section 1.05) of any such instrument or of a writing
appointing any such agent shall be sufficient for any purpose of this Indenture
and (subject to Section 6.01 hereof) conclusive in favor of the Trustee and the
Company, if made in the manner provided in this Section.

          (b)  The fact and date of the execution by any Person of any such
instrument or writing may be proved in any reasonable manner which the Trustee
deems sufficient including, without limitation, by verification from a notary
public or signature guarantee.

          (c)  The ownership of Notes shall be proved by the Note Register.

          (d)  Any request, demand, authorization, direction, notice, consent,
waiver or other action by the Holder of any Note shall bind every future Holder
of the same Note or the Holder of every Note issued upon the transfer thereof or
in exchange therefor or in lieu thereof to the same extent as the original
Holder, in
<PAGE>
 
                                     -19-

respect of anything done, suffered or omitted to be done by the Trustee, any
Paying Agent or the Company in reliance thereon, whether or not notation of such
action is made upon such Note.

          Section 1.06.  Notices, etc., to the Trustee and the Company.
                         ---------------------------------------------

          Any request, demand, authorization, direction, notice, consent, waiver
or Act of Holders or other document provided or permitted by this Indenture to
be made upon, given or furnished to, or filed with:

          (a)  the Trustee by any Holder or by the Company shall be sufficient
     for every purpose hereunder if made, given, furnished or filed, in writing,
     to or with the Trustee at its Corporate Trust Office or at any other
     address previously furnished in writing to the Holders and the Company by
     the Trustee or at the office of any drop agent specified by or on behalf of
     the Trustee to the Holders and the Company from time to time; and

          (b)  the Company by the Trustee or by any Holder shall be sufficient
      for every purpose (except as otherwise expressly provided herein)
      hereunder if in writing and mailed, first-class postage prepaid, to the
      Company, addressed to it at 1004 East Illinois Street, Assumption,
      Illinois 62510, Attention: John W. Funk, with a copy to Mayer, Brown &
      Platt, 190 South LaSalle Street, Chicago, Illinois 60610, Attention: Paul
      Theiss, or at any other address previously furnished in writing to the
      Trustee by the Company.

          Section 1.07.  Notice to Holders; Waiver.
                         ------------------------- 

          Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise expressly provided herein)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, at the address of such Holder as it appears in the Note Register,
not later than the latest date, and not earlier than the earliest date,
prescribed for the giving of such notice.  In any case where notice to Holders
is given by mail, neither the failure to mail such notice, nor any defect in any
notice so mailed, to any particular Holder shall affect the sufficiency of such
notice with respect to other Holders.  Any notice when mailed to a Holder in the
aforesaid manner shall be conclusively deemed to have been received by such
Holder whether or not actually received by such Holder.  Where this Indenture
provides for notice in any manner, such notice may be waived in writing by the
Person entitled to receive such notice, either before or after the event, and
such waiver shall be the equivalent of such notice.  Waivers of notice by
Holders shall be filed with the Trustee, but such filing shall not be a
condition precedent to the validity of any action taken in reliance upon such
waiver.

          In case by reason of the suspension of regular mail service or by
reason of any other cause, it shall be impracticable to mail notice of any event
as required by any provision of this Indenture, then any method of giving such
notice as shall be satisfactory to the Trustee shall be deemed to be a
sufficient giving of such notice.

          Section 1.08.  Conflict with Trust Indenture Act.
                         --------------------------------- 

          If any provision hereof limits, qualifies or conflicts with any
provision of the Trust Indenture Act or another provision which is required or
deemed to be included in this Indenture by any of the provisions of the Trust
Indenture Act, such provision or requirement of the Trust Indenture Act shall
control.
<PAGE>
 
                                     -20-

          If any provision of this Indenture modifies or excludes any provision
of the Trust Indenture Act that may be so modified or excluded, such provision
of the Trust Indenture Act shall be deemed to apply to this Indenture as so
modified or excluded, as the case may be, if this Indenture shall then be
qualified under the TIA.

          Section 1.09.  Effect of Headings and Table of Contents.
                         ---------------------------------------- 

          The Article and Section headings herein and the Table of Contents are
for convenience only and shall not affect the construction hereof.

          Section 1.10.  Successors and Assigns.
                         ----------------------

Trustee shall bind their respective successors and assigns, whether so expressed

invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

          Section 1.12.  Benefits of Indenture.
                         --------------------- 

          Nothing in this Indenture or in the Notes issued pursuant hereto,
express or implied, shall give to any Person (other than the parties hereto and
their successors hereunder, any Paying Agent and the Holders) any benefit or any
legal or equitable right, remedy or claim under this Indenture, except as
provided in Article Thirteen and Article Fourteen.

          SECTION 1.13.  GOVERNING LAW.
                         ------------- 

          THIS INDENTURE, THE NOTES AND THE GUARANTEES SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK (WITHOUT GIVING

                         -------------------------- 

          No director, officer, employee or stockholder of the Company or any
Guarantor, as such, shall have any liability for any obligations of the Company

of Notes by accepting a Note waives and releases all such liability, and such
waiver and release is part of the consideration for the issuance of the Notes.

                         ------------------------- 

          All covenants and agreements in this Indenture shall be given
independent effect so that if a particular action or condition is not permitted
by any of such covenants, the fact that it would be permitted by an exception
to, or be otherwise within the limitations of, another covenant shall not avoid
the occurrence of a Default if such action is taken or condition exists.

          Section 1.16.  Exhibits and Schedules.
                         ----------------------

          Notes will initially be issued in either of the following forms:

          (a)  Notes offered and sold in reliance on Rule 144A issued initially
     in the form of one or more global Notes in registered form, substantially
     in the form set forth in Exhibit A (the "U.S. Global Note"), deposited with
                              ---------                                         
     the Trustee, as custodian for the Depositary, duly executed by the Company
     and authenticated by the Trustee as hereinafter provided and shall bear the
     legend set forth in Section 2.03 hereof.  The aggregate principal amount of
     the U.S. Global Note may from time to time be increased or decreased by
     adjustments made on the records of the Trustee, as custodian for the
     Depositary.

          (b)  Notes offered and sold in offshore transactions in reliance on
     Regulation S represented upon issuance by a temporary global Note (the
     "Offshore Global Note" and, together with the U.S. Global Note, the "Global
     Notes"), which will be exchangeable for certificated Notes in registered
     form in substantially the form set forth in Exhibit A (the "Offshore
                                                 ---------               
     Physical Notes") only upon the expiration of the "40-day restricted period"
     within the meaning of Rule 903(c)(3) of Regulation S.

          Subsequent to the initial issuance of the Global Notes provided for in
paragraphs (a) and (b) above, physical certificates for notes transferred in
reliance on any exemption from registration under the Securities Act, other than
as described in the preceding two paragraphs, shall be issued in substantially
the form set forth in Exhibit A, subject to the Company's and the Trustee's
                      ---------                                            
right prior to any such transfer to require the delivery of an Opinion of
Counsel, certifications and/or other information satisfactory to each of them
(the "U.S. Physical Notes").  The Offshore Physical Notes and the U.S. Physical
Notes are sometimes collectively herein referred to as the "Physical Notes."
Physical Notes may initially be registered in the name of the Depositary or a
nominee of such Depositary and be delivered to the Trustee as custodian for such
Depositary.  Beneficial owners of Physical Notes, however, may request
registration of such Physical Notes in their names or the names of their
nominees.

          Section 2.02.  Execution and Authentication; Aggregate Principal 
                         ------------------------------------------------- 
Amount.
- ------

          The Notes shall be executed on behalf of the Company by two Officers
of the Company. The signature of any Officer on the Notes may be manual or
facsimile.

          If an Officer or Assistant Secretary whose manual or facsimile
signature is on a Note was an Officer or Assistant Secretary at the time of such
execution but no longer holds that office or position at the time the Trustee
authenticates the Note, the Note shall nevertheless be valid.

          No Note shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose, unless there appears on such Note a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any Note
shall be conclusive evidence, and the only evidence, that such Note has been
duly authenticated and delivered hereunder.

          The Trustee shall authenticate (i) Initial Notes for original issue in
the aggregate principal amount not to exceed $100,000,000 and (ii) Exchange
Notes from time to time for issue only in exchange for a like principal amount
of Initial Notes, in each case upon a written order of the Company in the form
of an Officers' Certificate. The Officers' Certificate shall specify the amount
of Notes to be authenticated and the date on which the Notes are to be
authenticated, whether the Notes are to be Initial Notes or Exchange Notes and
whether the Notes are to be issued as Physical Notes or Global Notes or such
other information as the
<PAGE>
 
                                     -23-

Trustee may reasonably request. The aggregate principal amount of Notes
outstanding at any time may not exceed $100,000,000, except as provided in
Section 3.05 hereof.

          The Trustee may appoint an authenticating agent (the "Authenticating
Agent") reasonably acceptable to the Company to authenticate Notes. Unless
otherwise provided in the appointment, an Authenticating Agent may authenticate
Notes whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such Authenticating
Agent. An Authenticating Agent has the same rights as an agent to deal with the
Company or with any Affiliate of the Company.

          Section 2.03.  Restrictive Legends.
                         -------------------

     HEREIN, THE TERMS "OFFSHORE TRANSACTION," "UNITED STATES" AND
     "U.S. PERSON" HAVE THE RESPECTIVE MEANINGS GIVEN TO THEM BY
     REGULATION S UNDER THE SECURITIES ACT.

          Each Global Note shall also bear a legend on the face thereof in
substantially the following form:

     UNLESS AND UNTIL IT IS EXCHANGED IN WHOLE OR IN PART FOR

the Depositary or its custodian.
<PAGE>
 
                                     -25-

          (1)  So long as the Notes are eligible for book-entry settlement with
the Depositary, or unless otherwise required by law, the Global Notes initially
shall (i) be registered in the name of the Depositary or the nominee of such
Depositary, (ii) be delivered to the Trustee as custodian for such Depositary
and (iii) bear legends as set forth in Section 2.03.

          Members of, or participants in, the Depositary ("Agent Members") shall
                                                           ------------- 
have no rights under this Indenture with respect to any Global Note held on
their behalf by the Depositary, or the Trustee as its custodian, or under the
Global Notes, and the Depositary may be treated by the Company, the Trustee and
any agent of the Company or the Trustee as the absolute owner of the Global
Notes for all purposes whatsoever. Notwithstanding the foregoing, nothing herein
shall prevent the Company, the Trustee or any Agent of the Company or the
Trustee from giving effect to any written certification, proxy or other
authorization furnished by the Depositary or impair, as between the Depositary
and its Agent Members, the operation of customary practices governing the
exercise of the rights of a Holder of any Note.

          (2)  Transfers of the Global Notes shall be limited to transfers in
whole, but, subject to the immediately succeeding sentence, not in part, to the
Depositary, its successors or their respective nominees. Interests of beneficial
owners in the Global Notes may be transferred or exchanged for Physical Notes in
accordance with the rules and procedures of the Depositary and the provisions of
Section 2.05 hereof. In addition, Physical Notes shall be transferred to all
beneficial owners in exchange for their beneficial interests in the Global Notes
if (i) the Depositary notifies the Company that it is unwilling or unable to
continue as Depositary for the Global Notes and a successor depositary is not
appointed by the Company within 90 days of such notice or (ii) an Event of
Default has occurred and is continuing and the Note Registrar has received a
written request from the Depositary to issue Physical Notes.

          (3)  In connection with any transfer or exchange of a portion of the
beneficial interest in a Global Note to beneficial owners pursuant to paragraph
(2), the Note Registrar shall (if one or more Physical Notes are to be issued)
reflect on its books and records the date and a decrease in the principal amount
of the Global Note in an amount equal to the principal amount of the beneficial
interest in the Global Note to be transferred, and the Company shall execute,
and the Trustee shall authenticate and deliver, one or more Physical Notes of
like tenor and amount.

          (4)  In connection with the transfer of the beneficial interests in an
entire Global Note to beneficial owners pursuant to paragraph (2), the Global
Note shall be deemed to be surrendered to the Trustee for cancellation, and the
Company shall execute, and the Trustee shall authenticate and deliver to each
beneficial owner identified by the Depositary in exchange for its beneficial
interest in the Global Note, an equal aggregate principal amount of Physical
Notes of authorized denominations.
 
          (5)  Any Physical Note constituting a Restricted Security delivered in
exchange for a beneficial interest in a Global Note pursuant to paragraph (2) or
(3) shall, except as otherwise provided by paragraphs (1)(a)(x) and (3) of
Section 2.05 hereof, bear the Private Placement Legend.

          (6)  The owner of a beneficial interest in a Global Note may grant
proxies and otherwise authorize any person, including Agent Members and persons
that may hold interests through Agent Members, to take any action which a Holder
is entitled to take under this Indenture or the Notes.

Private Placement Legend unless (i) the requested transfer is after the second

          The additional terms and provisions contained in the forms of Notes
and the Guarantees, annexed hereto as Exhibits A and E, respectively, shall
                                      ----------------   
constitute, and are hereby expressly made, a part of this Indenture and, to the
extent applicable, the Company and the Trustee, by their execution and delivery
of this Indenture, expressly agree to such terms and provisions and to be bound
thereby.

          Section 3.02.  Denominations.
                         ------------- 

          The Notes shall be issuable only in fully registered form without
coupons and in denominations of $1,000 and any integral multiple thereof.

          Section 3.03.  Temporary Notes.
                         --------------- 

          Pending the preparation and delivery of definitive Notes, the Company
may execute, and upon Company Order the Trustee shall authenticate and deliver,
temporary Notes. Temporary Notes may be printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Notes in lieu of which they are
issued and with such appropriate insertions, omissions, substitutions and other
variations as the Officers executing such Notes may consider appropriate, as
conclusively evidenced by their execution of such Notes.

          If temporary Notes are issued, the Company will cause definitive Notes
to be prepared without unreasonable delay. After the preparation of definitive
Notes, the temporary Notes shall be exchangeable for definitive Notes upon
surrender of the temporary Notes at the office or agency of the Company
designated for such purpose pursuant to Section 10.02, without charge to the
Holder. Upon surrender for cancellation of any one or more temporary Notes the
Company shall execute and the Trustee shall authenticate and deliver in exchange
therefor a like principal amount of definitive Notes of authorized
denominations. Until so exchanged the temporary Notes shall in all respects be
entitled to the same benefits under this Indenture as definitive Notes.

          Section 3.04.  Registration, Registration of Transfer and Exchange.
                         --------------------------------------------------- 

          The Company shall cause to be kept at the Corporate Trust Office a
register (the register maintained in such office and in any other office or
agency designated pursuant to Section 10.02 being herein sometimes referred to
as the "Note Register") in which, subject to such reasonable regulations as the
Person appointed as being responsible for the keeping of the Note Register (the
"Note Registrar") may prescribe, the Company shall provide for the registration
of Notes and of transfers of Notes. The Note Register shall be in written form
or in any form capable of being converted into written form within a reasonable
period of time. The Trustee is hereby initially appointed Note Registrar for the
purpose of registering Notes and transfers of Notes as herein provided. The
Company may appoint one or more co-registrars.

          Upon surrender for registration of transfer of any Note at the office
or agency of the Company designated pursuant to Section 10.02, the Company shall
execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Notes of any authorized
denomination or denominations, of a like aggregate principal amount and bearing
such restrictive legends as may be required by Section 2.03.

          At the option of the Holder, Notes in certificated form may be
exchanged for other Notes of any authorized denomination or denominations, of a
like aggregate principal amount, upon surrender of the Notes to be exchanged at
such office or agency. Whenever any Notes are so surrendered for exchange, the
<PAGE>
 
                                     -29-

Company shall execute, and the Trustee shall authenticate and deliver, the Notes
which the Holder making the exchange is entitled to receive.

          All Notes issued upon any registration of transfer or exchange of
Notes shall be the valid obligations of the Company, evidencing the same
indebtedness, and entitled to the same benefits under this Indenture, as the
Notes surrendered upon such registration of transfer or exchange and no such
transfer or exchange shall constitute a repayment of any obligation nor create
any new obligations of the Company.

          Every Note presented or surrendered for registration of transfer, or
for exchange or redemption, shall (if so required by the Company, the Trustee,
the Note Registrar or any co-registrar) be duly endorsed or be accompanied by a
written instrument of transfer in form satisfactory to the Company, the Trustee,
and the Note Registrar or any co-registrar, duly executed by the Holder thereof
or his attorney duly authorized in writing.

          No service charge shall be made to a Holder for any registration of
transfer or exchange or redemption of Notes, but the Company may require payment
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in connection with any registration of transfer or exchange of Notes,
other than exchanges pursuant to Section 3.03, 9.05, 10.14, 10.15 or 11.08 not
involving any transfer.

          None of the Company, the Trustee, the Note Registrar or any co-
registrar shall be required (a) to issue, register the transfer of or exchange
any Note during a period beginning at the opening of business 15 days before the
mailing of a notice of redemption of the Notes selected for redemption and
ending at the close of business on the day of such mailing, (b) to register the
transfer of or exchange any Note so selected for redemption in whole or in part,
except the unredeemed portion of Notes being redeemed in part or (c) to issue,
register, transfer or exchange any Note during a Change of Control Offer or an
Asset Sale Offer, if such note is tendered pursuant to such Change of Control
Offer or Asset Sale Offer.

          When Notes are presented to the Note Registrar with a request to
register the transfer or to exchange them for an equal principal amount of Notes
of other authorized denominations, the Registrar shall register the transfer or
make the exchange as requested if its requirements for such transactions are
met. To permit registrations of transfers and exchanges, the Company shall
execute and the Trustee shall authenticate Notes at the Note Registrar's
request.

          Section 3.05.  Mutilated, Destroyed, Lost and Stolen Notes.
                         ------------------------------------------- 

          If (a) any mutilated Note is surrendered to the Trustee, or (b) the
Company and the Trustee receive evidence to their satisfaction of the
destruction, loss or theft of any Note, and there is delivered to the Company
and the Trustee, such security or indemnity, in each case, as may be required by
them to save each of them harmless from any loss which either of them may suffer
if a Note is replaced, then, in the absence of notice to the Company or the
Trustee that such Note has been acquired by a bona fide purchaser, the Company
shall execute and the Trustee shall authenticate and deliver, in exchange for
any such mutilated Note or in lieu of any such destroyed, lost or stolen Note, a
replacement Note of like tenor and principal amount, bearing a number not
contemporaneously outstanding.

          Upon the issuance of any replacement Notes under this Section, the
Company may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.
<PAGE>
 
                                     -30-

          Every replacement Note issued pursuant to this Section in lieu of any
destroyed, lost or stolen Note shall constitute an original additional
contractual obligation of the Company, whether or not the destroyed, lost or
stolen Note shall be at any time enforceable by anyone, and shall be entitled to
all benefits of this Indenture equally and proportionately with any and all
other Notes duly issued hereunder.

          The provisions of this Section are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Notes.

          Section 3.06.  Payment of Interest; Interest Rights Preserved.
                         ---------------------------------------------- 

          Interest on any Note which is payable, and is punctually paid or duly
provided for, on any Interest Payment Date shall be paid by check or wire
transfer to the Person in whose name that Note (or one or more predecessor
Notes) is registered at the close of business on the Regular Record Date for
such interest.

          Any interest on any Note which is payable, but is not punctually paid
or duly provided for, on any Interest Payment Date and interest on such
defaulted interest at the then applicable interest rate borne by the Notes, to
the extent lawful (such defaulted interest and interest thereon herein
collectively called "Defaulted Interest"), shall forthwith cease to be payable
to the Holder on the Regular Record Date and such Defaulted Interest may be paid
by the Company, at its election in each case, as provided in subsection (a) or
(b) below:

          (a)  The Company may elect to make payment of any Defaulted Interest
     to the Persons in whose names the Notes (or their respective predecessor
     Notes) are registered at the close of business on a Special Record Date for
     the payment of such Defaulted Interest, which shall be fixed in the
     following manner. The Company shall notify the Trustee in writing at least
     20 days before such payment date of the amount of Defaulted Interest
     proposed to be paid on each Note and the date of the proposed payment, and
     at the same time the Company shall deposit with the Trustee an amount of
     money equal to the aggregate amount proposed to be paid in respect of such
     Defaulted Interest or shall make arrangements satisfactory to the Trustee
     for such deposit prior to the date of the proposed payment, such money when
     deposited to be held in trust for the benefit of the Persons entitled to
     such Defaulted Interest as in this subsection (a) provided. Thereupon the
     Trustee shall fix a Special Record Date for the payment of such Defaulted
     Interest which shall be not more than 15 days and not less than 10 days
     prior to the date of the proposed payment and not less than 10 days after
     the receipt by the Trustee of the notice of the proposed payment. The
     Trustee shall promptly notify the Company in writing of such Special Record
     Date. In the name and at the expense of the Company, the Trustee shall
     cause notice of the proposed payment of such Defaulted Interest and the
     Special Record Date therefor to be mailed, first-class postage prepaid, to
     each Holder at its address as it appears in the Note Register, not less
     than 10 days prior to such Special Record Date. Notice of the proposed
     payment of such Defaulted Interest and the Special Record Date therefor
     having been so mailed, such Defaulted Interest shall be paid to the Persons
     in whose names the Notes (or their respective predecessor Notes) are
     registered on such Special Record Date and shall no longer be payable
     pursuant to the following subsection (b).

          (b)  any other lawful manner not inconsistent with the requirements of
     any securities exchange on which the Notes may be listed, and upon such
     notice as may be required by such exchange, if, after written notice given
     by the Company to the Trustee of the proposed payment pursuant to this
     subsection (b), such payment shall be deemed practicable by the Trustee.
<PAGE>
 
                                     -31-

          Subject to the foregoing provisions of this Section, each Note
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Note shall carry the rights to interest accrued and
unpaid, and to accrue, which were carried by such other Note.

          Section 3.07.  Persons Deemed Owners.
                         --------------------- 

          Prior to and at the time of due presentment for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name any Note is registered in the Note Register
as the owner of such Note for the purpose of receiving payment of principal of,
premium, if any, and (subject to Section 3.06) interest on such Note and for all
other purposes whatsoever, whether or not such Note shall be overdue, and
neither the Company, the Trustee nor any agent of the Company or the Trustee
shall be affected by notice to the contrary.

          Section 3.08.  Cancellation.
                         ------------ 

          All Notes surrendered for payment, redemption, registration of
transfer or exchange shall be delivered to the Trustee and, if not already
cancelled, shall be promptly cancelled by it. The Company may at any time
deliver to the Trustee for cancellation any Notes previously authenticated and
delivered hereunder which the Company may have acquired in any manner
whatsoever, as evidenced by a Company Order instructing the Trustee that all
Notes so delivered shall be promptly cancelled by the Trustee. No Notes shall be
authenticated in lieu of or in exchange for any Notes cancelled as provided in
this Section 3.08, except as expressly permitted by this Indenture. Cancelled
Notes held by the Trustee shall be disposed of as directed by a Company Order;
provided, however, that the Trustee shall not be required to destroy such
- --------  -------                                                        
cancelled Notes.  The Trustee shall provide the Company with a list of all Notes
that have been cancelled from time to time as requested by the Company.

          Section 3.09.  Computation of Interest.
                         ----------------------- 

          Interest on the Notes shall be computed on the basis of a 360-day year
of twelve 30-day months.

          Section 3.10.  Legal Holidays.
                         -------------- 

          In any case where any Interest Payment Date, Redemption Date, date
established for the payment of Defaulted Interest or Stated Maturity of any Note
shall not be a Business Day, then (notwithstanding any other provision of this
Indenture or of the Notes) payment of principal, premium, if any, or interest
need not be made on such date, but may be made on the next succeeding Business
Day with the same force and effect as if made on the Interest Payment Date,
Redemption Date, date established for the payment of Defaulted Interest or at
the Stated Maturity, as the case may be, and no interest shall accrue with
respect to such payment for the period from and after such Interest Payment
Date, Redemption Date, date established for the payment of Defaulted Interest or
Stated Maturity, as the case may be, to the next succeeding Business Day.

          Section 3.11.  CUSIP Number.
                         ------------ 

          The Company in issuing the Notes may use "CUSIP" numbers (if then
generally in use), and if so, the Trustee may use the CUSIP numbers in notices
of redemption or exchange as a convenience to Holders; provided, however, that
                                                       --------  -------      
any such notice may state that no representation is made as to the correctness
or 
<PAGE>
 
                                     -32-

accuracy of the CUSIP number printed in the notice or on the Notes, and that
reliance may be placed only on the other identification numbers printed on the
Notes. All Initial Notes shall bear identical CUSIP numbers and all Exchange
Notes shall bear identical CUSIP numbers. The Company shall promptly notify the
Trustee in writing of any change in the CUSIP number of the Notes.

          Section 3.12.  Payment of Additional Interest Under Registration
                         -------------------------------------------------
Rights Agreement.
- ---------------- 

          Under certain circumstances the Company will be obligated to pay
certain additional amounts of interest to the Holders, as more particularly set
forth in section 2(e) of the Registration Rights Agreement.  The terms of
Section 2(e) the Registration Rights Agreement are hereby incorporated herein by
reference and the Company shall be obligated to provide a copy of such
Registration Rights Agreement to the Trustee.


                                 ARTICLE FOUR

                       DEFEASANCE OR COVENANT DEFEASANCE

          Section 4.01.  Defeasance.
                         ---------- 

          The Company may, at its option and at any time, terminate the
obligations of the Company and the Guarantors, if any, with respect to
Outstanding Notes ("defeasance"). Such defeasance means that the Company will be
deemed to have paid and discharged the entire Indebtedness represented by the
Outstanding Notes, except for (i) the rights of holders of Outstanding Notes to
receive payment in respect of the principal of, premium, if any, and interest on
such Notes when such payments are due, (ii) the Company's obligations to issue
temporary Notes, register the transfer or exchange of any Notes, replace
mutilated, destroyed, lost or stolen Notes and maintain an office or agency for
payments in respect of the Notes, (iii) the rights, powers, trusts, duties and
immunities of the Trustee and (iv) the defeasance provisions of the Indenture.

          Section 4.02.  Covenant Defeasance.
                         ------------------- 

          In addition, the Company may, at its option and at any time, elect to
terminate the obligations of the Company and any Guarantor with respect to
Sections 10.05 through 10.20 and the provisions of Article Eight, and any
omission to comply with such obligations will not constitute a Default or an
Event of Default with respect to the Notes ("covenant defeasance"). For this
purpose, such covenant defeasance means that, with respect to the Outstanding
Notes, the Company and the Guarantors may omit to comply with and shall have no
liability in respect of any term, condition or limitation set forth in any such
covenant, whether directly or indirectly, by reason of any reference elsewhere
herein to any such covenant or by reason of any reference in any such covenant
to any other provision herein or in any other document and such omission to
comply shall not constitute a Default or an Event of Default under Section
5.01(c), (d) or (e), provided as specified above, the remainder of this
Indenture and such Outstanding Notes shall be unaffected thereby.

          Section 4.03.  Conditions to Defeasance or Covenant Defeasance.
                         ----------------------------------------------- 

          In order to exercise either defeasance or covenant defeasance:

          (1) the Company must irrevocably deposit with the Trustee, in trust,
     for the benefit of the Holders, cash in United States dollars, U.S.
     Government Obligations, or a combination thereof, in 
<PAGE>
 
                                     -33-

     such amounts as will be sufficient, in the opinion of a nationally
     recognized firm of independent public accountants, to pay the principal of,
     premium, if any, and interest on the outstanding Notes at maturity;

          (2) the Company shall have delivered to the Trustee an Opinion of
     Counsel to the effect that the Holders of the Outstanding Notes will not
     recognize income, gain or loss for federal income tax purposes as a result
     of such defeasance or covenant defeasance and will be subject to federal
     income tax on the same amounts, in the same manner and at the same times as
     would have been the case if such defeasance or covenant defeasance had not
     occurred (in the case of defeasance, such opinion must refer to and be
     based upon a ruling of the Internal Revenue Service or a change in
     applicable federal income tax laws);

          (3) no Default shall have occurred and be continuing on the date of
     such deposit;

          (4) such defeasance or covenant defeasance shall not cause the Trustee
     to have a conflicting interest with respect to any securities of the
     Company or any Guarantor;

          (5) such defeasance or covenant defeasance shall not result in a
     breach or violation of, or constitute a default under, any material
     agreement or instrument to which the Company or any Guarantor is a party or
     by which it is bound;

          (6) the Company shall have delivered to the Trustee an Opinion of
     Counsel to the effect that (A) the trust funds will not be subject to any
     rights of Holders of Senior Indebtedness, including, without limitation,
     those arising under this Indenture and (B) after the 91st day following the
     deposit, the trust funds will not be subject to the effect of any
     applicable bankruptcy, insolvency, reorganization or similar laws affecting
     creditors' rights generally; and

          (7) the Company shall have delivered to the Trustee an Officers'
     Certificate and an Opinion of Counsel, each stating that all conditions
     precedent under this Indenture to either defeasance or covenant defeasance,
     as the case may be, have been complied with.

          Opinions and certificates required to be delivered under this Section
shall be in compliance with the requirements set forth in Section 1.04 and this
Section 4.03.

          Section 4.04.  Deposited Money and U.S. Government Obligations To Be
                         -----------------------------------------------------
Held in Trust; Etc.
- -------------------

          Subject to the provisions of the last paragraph of Section 10.03, all
money and U.S. Government Obligations (including the proceeds thereof) deposited
with the Trustee (or such other Person that would qualify to act as successor
trustee under Article Six, collectively for purposes of this Section 4.04, the
"Trustee") pursuant to Section 4.03 in respect of the Company's election under
either Section 4.01 or 4.02, shall be held in trust and applied by the Trustee,
in accordance with the provisions of such Notes and this Indenture, to the
payment, either directly or through any Paying Agent (other than the Company or
any Affiliate of the Company) as the Trustee may determine, to the Holders of
such Notes of all sums due and to become due thereon in respect of principal,
premium, if any, and interest, but such money need not be segregated from other
funds except to the extent required by law.
<PAGE>
 
                                     -34-

          The Company shall pay and indemnify the Trustee and its agents and
hold them harmless against any tax, fee or other charge imposed on or assessed
against the U.S. Government Obligations deposited pursuant to Section 4.03 or
the principal, premium, if any, and interest received in respect thereof other
than any such tax, fee or other charge which by law is for the account of the
Holders of the Defeased Notes.

          Anything in this Article Four to the contrary notwithstanding, the
Trustee shall deliver to the Company from time to time upon Company Request any
money or U.S. Government Obligations held by it as provided in Section 4.03
hereof which, in the opinion of a nationally-recognized firm of independent
public accountants expressed in a written certification thereof to the Trustee,
are in excess of the amount thereof which would then be required to be deposited
to effect an equivalent defeasance or covenant defeasance.

          Section 4.05.  Reinstatement.
                         ------------- 

          If the Trustee or Paying Agent is unable to apply any money or U.S.
Government Obligations in accordance with Section 4.03, by reason of any order
or judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, then the obligations of the Company and
each of the Guarantors under this Indenture, the Notes and the Guarantees shall
be revived and reinstated as though no deposit had occurred pursuant to Section
4.03, until such time as the Trustee or Paying Agent is permitted to apply all
such money and U.S. Government Obligations in accordance with Section 4.03;
provided, however, that if the Company or the Guarantors make any payment of
principal, premium, if any, or interest on any Note following the reinstatement
of its obligations, the Company or the Guarantors, as the case may be, shall be
subrogated to the rights of the Holders of such Notes to receive such payment
from the money and U.S. Government Obligations held by the Trustee or Paying
Agent.

          Section 4.06.  Repayment to Company.
                         -------------------- 

          The Trustee shall pay to the Company (or, if appropriate, the
Guarantors) upon Company Request any money held by it for the payment of
principal or interest that remains unclaimed for two years. After payment to the
Company or the Guarantors, Noteholders entitled to money must look to the
Company and the Guarantors for payment as general creditors unless an applicable
abandoned property law designates another person and all liability of the
Trustee or Paying Agent with respect to such money shall thereupon cease.


                                 ARTICLE FIVE

                                   REMEDIES

          Section 5.01.  Events of Default.
                         ----------------- 

          "Event of Default," wherever used herein, means any one of the
           ----------------

     optional redemption, required purchase, scheduled principal payment or
     otherwise); or

          (b) default in the payment of an installment of interest on any of the
     Notes, when due and payable, continued for 30 days or more; or

          (c) the Company or any Guarantor fails to comply with any of its
     obligations described under Article Eight, Section 10.14 or Section 10.15;

     aggregate principal amount of the Notes then outstanding; or

          (e) default or defaults under one or more agreements, indentures or
     instruments under which the Company or any Restricted Subsidiary then has
     outstanding Indebtedness in excess of $7.5 million individually or in the
     aggregate and either (a) such Indebtedness is already due and payable in
     full or (b) such default or defaults results in the acceleration of the
     maturity of such Indebtedness; or

          (f) any Note Guarantee ceases to be in full force and effect or is
     declared null and void or any Guarantor denies that it has any further
     liability under any Note Guarantee, or gives notice to such effect (other

     such Note Guarantee in accordance with Section 10.10) and such condition
     shall have continued for a period of 30 days after notice to the Company by
     the Trustee; or

          (g) one or more judgments, orders or decrees of any court or

     stay of enforcement of such judgment, order or decree, by reason of a
     pending appeal or otherwise, shall not be in effect; or

          (h) (i) the Company or any Material Subsidiary commences a voluntary
     case or proceeding under any applicable Bankruptcy Law or any other case or

     (y) makes an assignment for the benefit of creditors or (z) admits in
     writing its inability to pay its debts generally as they become due.

          The Company shall provide an Officers' Certificate to the Trustee
promptly upon any officer of the Company obtaining knowledge of any Default or
Event of Default that has occurred and, if applicable, describe such Default or
Event of Default and the status thereof.

          Section 5.02.  Acceleration of Maturity; Rescission and Annulment.
                         -------------------------------------------------- 

          If an Event of Default (other than as specified in Section 5.01(h)
with respect to the Company) shall occur and be continuing, the Trustee, by
notice to the Company, or the Holders of at least 25% in aggregate principal
amount of the Notes then outstanding, by notice to the Trustee and the Company,
may declare the principal of, premium, if any, and accrued interest on all of
the outstanding Notes due and payable immediately, upon which declaration all
such amounts payable in respect of the Notes will become and be immediately due
and payable; provided, however, that so long as the New Credit Agreement shall
be in force and effect, if an Event of Default shall have occurred and be
continuing (other than an Event of Default in Section 5.01(h) with respect to
the Company), any such acceleration shall not be effective until the earlier to
occur of (x) five business days following delivery of a notice of such
acceleration to the agent under the New Credit Agreement and (y) the
acceleration of any Indebtedness under the New Credit Agreement. If an Event of
Default specified in Section 5.01(h) above with respect to the Company occurs
and is continuing, then the principal of, premium, if any, and accrued interest
on all of the outstanding Notes will ipso facto become and be immediately due
and payable without any declaration or other act on the part of the Trustee or
any Holder of Notes.

          Notwithstanding the preceding paragraph, in the event of a declaration
of acceleration in respect of the Notes because an Event of Default specified in
Section 5.01(e) shall have occurred and be continuing, such declaration of
acceleration will be automatically annulled if the Indebtedness that is the
subject of such Event of Default has been discharged or paid (if permitted by
the terms thereof and this Indenture) or the requisite Holders thereof have
rescinded their declaration of acceleration in respect of such Indebtedness, and
written notice of such discharge or rescission, as the case may be, shall have
been given to the Trustee by the Company, within 60 days after such declaration
of acceleration in respect of the Notes and no other Event of Default has
occurred which has not been cured or waived during such 60-day period.

          After a declaration of acceleration, but before a judgment or decree
for payment of the money due has been obtained by the Trustee, the Holders of a
majority in aggregate principal amount of the outstanding Notes, by written
notice to the Company and the Trustee, may rescind such declaration if:

          (a) the Company has paid or deposited with the Trustee a sum
     sufficient to pay:

            (i) all sums paid or advanced by the Trustee under this Indenture
     and the reasonable compensation, expenses, disbursements and advances of
     the Trustee, its agents and counsel,

           (ii) all overdue interest on all Notes,

          (iii) the principal of and premium, if any, on any Notes which have
     become due otherwise than by such declaration of acceleration and interest
     thereon at the rate borne by the Notes, and

                                     -37-

           (iv) to the extent that payment of such interest is lawful, interest
     upon overdue interest at the rate borne by the Notes, and

          (b)  all Events of Default, other than the non-payment of principal
     of, premium, if any, and interest on the Notes that has become due solely
     by such declaration of acceleration, have been cured or waived.

                         -------------------------------------------------------
Trustee; Other Remedies.
- ----------------------- 

          The Company covenants that if an Event of Default in payment of
principal, premium or interest specified in Section 5.01(a) or 5.01(b) hereof
occurs and is continuing, the Company will, upon demand of the Trustee, pay to
the Trustee, for the benefit of the Holders of such Notes, the whole amount then
due and payable on such Notes for principal, premium, if any, and interest, with
interest upon the overdue principal, premium, if any, and, to the extent that
payment of such interest shall be legally enforceable, upon overdue installments
of interest, at the rate then borne by the Notes; and, in addition thereto, such
further amount as shall be sufficient to cover the costs and expenses of
collection, including the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel.

          If the Company fails to pay such amounts forthwith upon such demand,
the Trustee, in its own name and as trustee of an express trust, may, but is not
obligated under this paragraph to, institute a judicial proceeding for the
collection of the sums so due and unpaid and may, but is not obligated under
this paragraph to, prosecute such proceeding to judgment or final decree, and
may, but is not obligated under this paragraph to, enforce the same against the
Company, the Guarantors or any other obligor upon the Notes and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of
the property of the Company or any other obligor upon the Notes, wherever
situated.

          If an Event of Default occurs and is continuing, the Trustee may in
its discretion, but is not obligated under this paragraph to, (i) proceed to
protect and enforce its rights and the rights of the Holders under this
Indenture and the Notes by such appropriate private or judicial proceedings as
the Trustee shall deem most effectual to protect and enforce such rights,
whether for the specific enforcement of any covenant or agreement contained in
this Indenture or the Notes or in aid of the exercise of any power granted
herein or therein, or (ii) proceed to protect and enforce any other proper
remedy.  No recovery of any such judgment upon any property of the Company shall
affect or impair any rights, powers or remedies of the Trustee or the Holders.

          Section 5.04.  Trustee May File Proofs of Claims.
                         --------------------------------- 

          In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company, the Guarantors or any other obligor
upon the Notes, or the property of the Company, the Guarantors or of such other
obligor or their creditors, the Trustee (irrespective of whether the principal
of the Notes shall then be due and payable as therein expressed or by
declaration or otherwise and irrespective of whether the Trustee shall have made
any demand on the Company for the payment of overdue principal or interest)
shall be entitled and empowered, by intervention in such proceeding or
otherwise, but is not obligated under this paragraph

          (a) to file and prove a claim for the whole amount of principal,
     premium, if any, and interest owing and unpaid in respect of the Notes and
     to file such other papers or documents as may be

                                     -38-

     necessary or advisable in order to have the claims of the Trustee
     (including any claim for the reasonable compensation, expenses,
     disbursements and advances of the Trustee, its agents and counsel) and of
     the Holders allowed in such judicial proceeding, and

          (b) to collect and receive any moneys or other property payable or
     deliverable on any such claims and to distribute the same;

and any custodian, in any such judicial proceeding is hereby authorized by each
Holder to make such payments to the Trustee and, in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay the
Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 6.07 hereof.

          Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Notes or
the rights of any Holder thereof, or to authorize the Trustee to vote in respect
of the claim of any Holder in any such proceeding.

be prosecuted and enforced by the Trustee without the possession of any of the
Notes or the production thereof in any proceeding relating thereto, and any such
proceeding instituted by the Trustee shall be brought in its own name and as
trustee of an express trust, and any recovery of judgment shall, after provision
for the payment of the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, be for the ratable benefit of
the Holders of the Notes in respect of which such judgment has been recovered.

applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal, premium, if
any, or interest, upon presentation of the Notes and the notation thereon of the
payment if only partially paid and upon surrender thereof if fully paid:

          First: to the Trustee for amounts due under Section 6.07;

          Second: to Holders for interest accrued on the Notes, ratably,
     without preference or priority of any  kind, according to the amounts due
     and payable on the Notes for interest;

          Third: to Holders for principal amounts owing under the Notes,
     ratably, without preference or priority of any kind, according to the
     amounts due and payable on the Notes for principal and premium; and

          Fourth: to the Company or, to the extent the Trustee collects any
     amount from any Guarantor, to such Guarantor.

          The Trustee, upon prior written notice to the Company, may fix a

other Holders, or to obtain or to seek to obtain priority or preference over any
other Holders or to enforce any right under this Indenture or any Note except in
the manner provided in this Indenture and for the equal and ratable benefit of

right and remedy shall, to the extent permitted by law, be cumulative and in

     No delay or omission of the Trustee or of any Holder of any Note to
exercise any right or remedy accruing upon any Event of Default shall impair any

law to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by the Holders, as the case
may be.

     Section 5.12.  Control by Majority.
                    ------------------- 

     The Holders of not less than a majority in aggregate principal amount of
the Outstanding Notes shall have the right to direct the time, method and place
of conducting any proceeding for any remedy available to the Trustee, or

          (a) such direction shall not be in conflict with any rule of law or
     with this Indenture or any Note or expose the Trustee to liability; and

          (b) subject to the provisions of Section 315 of the TIA, the Trustee
     may take any other action deemed proper by the Trustee which is not

     on any Note (which may only be waived with the consent of each Holder of
     Notes affected); or

          (b) in respect of a covenant or provision under this Indenture which
     cannot be modified or amended without the consent of the Holder of each
     Outstanding Note affected.

     Upon any such waiver, such Default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured, for every purpose
of this Indenture; but no such waiver shall extend to any subsequent or other
Default or Event of Default or impair any right consequent thereon.

filing by any party litigant in such suit of an undertaking to pay the costs of
such suit, and that such court may in its discretion assess reasonable costs,

of redemption or repurchase, on or after the respective Redemption Dates or

                         --------------------------------------- 

          The Company covenants (to the extent that it may lawfully do so) that
it will not at any time insist upon, or plead, or in any manner whatsoever claim
or take the benefit or advantage of, any stay or extension law or any usury or
other law wherever enacted, now or at any time hereafter in force, which would
prohibit or forgive the Company from paying all or any portion of the principal
of, premium, if any, or interest on the Notes contemplated herein or in the
Notes or which may affect the covenants or the performance of this Indenture;
and the Company (to the extent that it may lawfully do so) hereby expressly

          (a) Except during the continuance of an Event of Default,

          (1) the Trustee undertakes to perform such duties and only such duties
     as are specifically set forth in this Indenture, and no implied covenants
     or obligations shall be read into this Indenture against the Trustee; and

          (2) in the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon certificates or opinions furnished to
     the Trustee and conforming to the requirements of this Indenture; but in
     the case of any such certificates or opinions which by any provision hereof
     are specifically required to be furnished to the Trustee, the Trustee or
     its counsel shall be under a duty to examine the same to determine whether
     or not they conform to the requirements of this Indenture.

          (b) In case an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a
prudent Person would exercise or use under the circumstances in the conduct of
such Person's own affairs.
<PAGE>
 
                                     -42-

          (c) No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own gross negligent action, its own gross
negligent failure to act, or its own willful misconduct, except that (i) this
paragraph does not limit the effect of paragraph (a) of this Section 6.01; (ii)
the Trustee shall not be liable for any error of judgment made in good faith by
an officer of the Trustee or upon advice of its counsel, unless it is proved
that the Trustee was grossly negligent in ascertaining the pertinent facts; and
(iii) the Trustee shall not be liable with respect to any action it takes or
omits to take in good faith in accordance with a direction received by it
pursuant to Section 5.12.

          (d) No provision of this Indenture shall require the Trustee to expend
or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties hereunder or to take or omit to take any action
under this Indenture or take any action at the request or direction of Holders
if it shall have reasonable grounds for believing that repayment of such funds
is not assured to it or it does not receive an indemnity satisfactory to it in
its sole discretion against such risk, liability, loss, fee or expense which
might be incurred by it in compliance with such request or direction.

          (e) Whether or not therein expressly so provided, every provision of
this Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this
Section 6.01.

Register, notice of such Default hereunder known to the Trustee; provided,
however, that, except in the case of a Default in the payment of the principal
of, premium, if any, or interest on any Note, the Trustee shall be protected in
withholding such notice if and so long as the board of directors, the executive
committee or a trust committee of Responsible Officers or counsel of the Trustee
in good faith determines that the withholding of such notice is in the interest
of the Holders.

          Section 6.03.  Certain Rights of Trustee.

     approval, appraisal, bond, debenture, note, coupon, security, other

     faith on its part, rely upon an Officers' Certificate of the Company;

     is an employee of the Trustee) or attorney appointed with due care by it
     hereunder; or

          (g) the Trustee shall not be charged with knowledge of any Default or

     of the Default or Event of Default, as the case may be, or (2) written

York. If such corporation publishes reports of condition at least annually,
pursuant to law or to the requirements of United States Federal, state,
territorial or District of Columbia supervising or examining authority, then for
the purposes of this Section, the combined capital and surplus of such
corporation shall be deemed to be its combined capital and surplus as set forth

Trustee.
- ------- 

          (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee under Section 6.11.
<PAGE>
 
                                     -45-

          (b) The Trustee, or any trustee or trustees hereinafter appointed, may
at any time resign by giving written notice thereof to the Company and the
Guarantors at least 30 Business Days prior to the date of such proposed
resignation.  Upon receiving such notice of resignation, the Company and the
Guarantors shall promptly appoint a successor trustee by written instrument, a
copy of which shall be delivered to the resigning Trustee and a copy to the
successor trustee.  If an instrument of acceptance by a successor Trustee shall
not have been delivered to the Trustee within 30 Business Days after the giving
of such notice of resignation, the resigning Trustee may, or any Holder who has
been a bona fide Holder of a Note for at least six months may, on behalf of
himself and all others similarly situated, petition any court of competent
jurisdiction for the appointment of a successor Trustee.  Such court may
thereupon, after such notice, if any, as it may deem proper, appoint a successor
trustee.

          (c) The Trustee may be removed at any time with 60 days written notice
by an Act of the Holders of a majority in principal amount of the Outstanding
Notes, delivered to the Trustee, the Company and the Guarantors.

          (d)  If at any time:

          (1) the Trustee shall fail to comply with the provisions of (S) 310(b)
     of the TIA in accordance with Section 6.08 hereof after written request
     therefor by the Company, the Guarantors or by any Holder who has been a
     bona fide Holder of a Note for at least six months, or

          (2) the Trustee shall cease to be eligible under Section 6.09 hereof
     and shall fail to resign after written request therefor by the Company, the
     Guarantors or by any such Holder, or

          (3) the Trustee shall become incapable of acting or shall be adjudged
     a bankrupt or insolvent, or a receiver of the Trustee or of its property
     shall be appointed or any public officer shall take charge or control of
     the Trustee or of its property or affairs for the purpose or
     rehabilitation, conservation or liquidation,

then, in any such case, (i) the Company or the Guarantors may remove the
Trustee, or (ii) subject to Section 5.14, the Holder of any Note who has been a
bona fide Holder of a Note for at least six months may, on behalf of himself and
all others similarly situated, petition any court of competent jurisdiction for
the removal of the Trustee and the appointment of a successor Trustee.  Such
court may thereupon, after such notice, if any, as it may deem proper and
prescribe, remove the Trustee and appoint a successor trustee.

          (e) If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, the
Company or the Guarantors shall promptly appoint a successor Trustee.  If,
within 60 days after such resignation, removal or incapability, or the
occurrence of such vacancy, and the Company or the Guarantors have not appointed
a successor Trustee, a successor Trustee shall be appointed by act of the
Holders of a majority in principal amount of the Outstanding Notes delivered to
the Company, the Guarantors and the retiring Trustee, the successor Trustee so
appointed shall, forthwith upon its acceptance of such appointment, become the
successor Trustee and supersede the successor Trustee appointed by the Company
and the Guarantors.  If no successor Trustee shall have been so appointed by the
Company or the Holders of the Notes and accepted appointment in the manner
hereinafter provided, the Holder of any Note who has been a bona fide Holder for
at least six months may, subject to Section 5.14, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the
appointment of a successor Trustee.

                                     -46-

          (f) The Company and the Guarantors shall give notice of each
resignation and each removal of the Trustee and each appointment of a successor
Trustee by mailing written notice of such event by first-class mail, postage
prepaid, to the Holders of Notes as their names and addresses appear in the Note
Register.  Each notice shall include the name of the successor Trustee and the
address of its Corporate Trust Office.

          Section 6.11.  Acceptance of Appointment by Successor.
                         -------------------------------------- 

          Every successor Trustee appointed hereunder shall execute, acknowledge
and deliver to the Company, the Guarantors and to the retiring Trustee an
instrument accepting such appointment, and thereupon the resignation or removal
of the retiring Trustee shall become effective and such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee as if originally named
as Trustee hereunder; but, nevertheless, on the written request of the Company,
the Guarantors or the successor Trustee, upon payment of amounts due it pursuant
to Section 6.07, such retiring Trustee shall duly assign, transfer and deliver
to the successor Trustee all moneys and property at the time held by it
hereunder and shall execute and deliver an instrument transferring to such
successor Trustee all the rights, powers, duties and obligations of the retiring
Trustee.  Upon request of any such successor Trustee, the Company and the
Guarantors shall execute any and all instruments for more fully and certainly
vesting in and confirming to such successor Trustee all such rights and powers.

          No successor Trustee with respect to the Notes shall accept
appointment as provided in this Section 6.11 unless at the time of such
acceptance such successor Trustee shall be eligible to act as Trustee under this
Article.

          Upon acceptance of appointment by any successor Trustee as provided in
this Section 6.11, the Company and the Guarantors shall give notice thereof to
the Holders of the Notes, by mailing such notice to such Holders at their
addresses as they shall appear on the Note Register. If the acceptance of
appointment is substantially contemporaneous with the resignation, then the
notice called for by the preceding sentence may be combined with the notice
called for by Section 6.10(f).  If the Company or the Guarantors fail to give
such notice within 10 days after acceptance of appointment by the successor
Trustee, the successor Trustee shall cause such notice to be given at the
expense of the Company.

          Section 6.12.  Successor Trustee by Merger, etc.
                         -------------------------------- 

          Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion, or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder without
the execution or filing of any paper or any further act on the part of any of
the parties hereto, provided such corporation shall be eligible under this
Article to serve as Trustee hereunder.

          In case at the time such successor to the Trustee under this Section
6.12 shall succeed to the trusts created by this Indenture any of the Notes
shall have been authenticated but not delivered, any such successor to the
Trustee may adopt the certificate of authentication of any predecessor Trustee
and deliver such Notes so authenticated; and, in case at that time any of the
Notes shall not have been authenticated, any successor to the Trustee under this
Section 6.12 may authenticate such Notes either in the name of any predecessor
hereunder or in the name of the successor Trustee; and in all such cases such
certificate shall have the full force which it is anywhere in the Notes or in
this Indenture provided that the certificate of the Trustee shall have been
authenticated.

                         ------------------------------------------------- 

          The Trustee shall comply with Section 311(a) of the TIA, excluding any
creditor relationship listed in (S) 311(b) of the TIA.  If the present or any

transfer, lease or otherwise dispose of all or substantially all of its
properties and assets as an entirety to, any Person or Persons, and the Company

Indenture and the Registration Rights Agreement, and in each case, such
Indenture and the Registration Rights Agreement shall remain in full force and
effect; (ii) immediately after giving effect to such transaction or series of
related transactions on a pro forma basis, no Default shall have occurred and be
continuing; and (iii) the Company, or the Surviving Person, as the case may be,

or series of transactions), could incur $1.00 of additional Indebtedness (other
than Permitted Indebtedness) under Section 10.11, provided, that the foregoing

                         --------------------- 

          Upon any consolidation or merger of the Company or any Guarantor or

          (i) to make any change that would provide any additional benefit or
     rights to the Holders or that does not adversely affect the rights of any
     Holder;

          provided, however, that the Company has delivered to the Trustee an
     Opinion of Counsel stating that such change does not materially adversely
     affect the legal rights of any Holder.

          Section 9.02.  With Consent of Holders.
                         ----------------------- 

          Except as provided in Section 9.01, other amendments and modifications
of this Indenture or the Notes may be made by the Company, the Guarantors, if
any, and the Trustee with the consent of the Holders of not less than a majority
of the aggregate principal amount of the outstanding Notes; provided, however,
that no such modification or amendment may, without the consent of the Holder of
each outstanding Note affected thereby,

          (i) change the maturity of the principal of or any installment of

     Indenture or the Notes which may not be amended, supplemented or waived
     without the consent of each Holder therein affected);

         (vi) reduce the percentage of the principal amount of outstanding Notes

        (vii) waive a default in the payment of principal of, interest on, or
     redemption payment with respect to, the Notes (except a rescission of
     acceleration of the Notes by the Holders thereof as provided in this

     acceleration);

       (viii) modify the ranking or priority of any Note or the Note Guarantee
     in respect thereof of any Guarantor or modify the definition of Senior

     Holders of the Notes; or

         (ix) release any Guarantor from any of its obligations under its Note
     Guarantee or this Indenture otherwise than in accordance with this
     Indenture.

          The Holders of a majority in aggregate principal amount of the
outstanding Notes, on behalf of all Holders of Notes, may waive compliance by
the Company and the Guarantors with certain restrictive provisions of this
Indenture. Subject to certain rights of the Trustee, as provided in this
Indenture, the Holders of a majority in aggregate principal amount of the Notes,

or exchange offer for the Notes), except a default in the payment of principal,
premium or interest or a default arising from failure to purchase any Notes
tendered pursuant to an optional redemption or repurchase, or a default in
respect of a provision hereunder that cannot be modified or amended without the
consent of the Holder of each Note that is affected.

          It shall not be necessary for the consent of the Holders under this
Section 9.02 to approve the particular form of any proposed amendment,
supplement or waiver, but it shall be sufficient if such consent approves the
substance thereof.

          Section 9.03.  Compliance with Trust Indenture Act.
                         ----------------------------------- 

          Every amendment of or supplement to this Indenture or the Notes shall
comply with the TIA as then in effect if this Indenture shall then be qualified
under the TIA.

          Section 9.04.  Effect of Supplemental Indentures.
                         --------------------------------- 

          Upon the execution of any supplemental indenture under this Article
Nine, this Indenture shall be modified in accordance therewith, and such
supplemental indenture shall form a part of this Indenture for all purposes; and
every Holder theretofore or thereafter authenticated and delivered hereunder
shall be bound thereby.

          Section 9.05.  Revocation and Effect of Consents.
                         --------------------------------- 

          Until an amendment or waiver becomes effective, a consent to it by a
Holder is a continuing consent by the Holder and every subsequent Holder of that
Note or portion of that Note that evidences the same debt as the consenting
Holder's Note, even if notation of the consent is not made on any note. Subject
to the following paragraph, any such Holder or subsequent Holder may revoke the
consent as to such Holder's Note or portion of such Note by notice to the
Trustee or the Company received before the date on which the Trustee receives an
Officers' Certificate certifying that the Holders of the requisite principal
amount of Notes have consented (and not theretofor revoked such consent) to the
amendment, supplement or waiver.
<PAGE>
 
                                     -52-

          The Company may, but shall not be obligated to, fix a record date for
the purpose of determining the Holders entitled to consent to any amendment,
supplement or waiver.  If a record date is fixed, then, notwithstanding the last
sentence of the immediately preceding paragraph, those Persons who were Holders
at such record date (or their duly designated proxies), and only those Persons,
shall be entitled to consent to such amendment, supplement or waiver or to
revoke any consent previously given, whether or not such Persons continue to be
Holders after such record date. No such consent shall be valid or effective for
more than 90 days after such record date.

          After an amendment, supplement or waiver becomes effective, it shall
bind every Holder of Notes, unless it makes a change described in any of clauses
(i) through (ix) of Section 9.02.  In that case, the amendment, supplement or
waiver shall bind each Holder of a Note who has consented to it and every
subsequent Holder of a Note or portion of a Note that evidences the same debt as
the consenting Holder's Note

          Section 9.06.  Notation on or Exchange of Notes.
                         -------------------------------- 

          If an amendment, supplement or waiver changes the terms of a Note, the
Trustee shall (in accordance with the specific direction of the Company) request
the Holder of the Note to deliver it to the Trustee. The Trustee shall (in
accordance with the specific direction of the Company) place an appropriate
notation on the Note about the changed terms and return it to the Holder.
Alternatively, if the Company or the Trustee so determines, the Company in

                         -------------------------------- 

          The Trustee shall sign any amendment, supplement or waiver authorized

          The Company will maintain in The City of New York, an office or agency
where Notes may be presented or surrendered for payment, where Notes and the
Guarantees may be surrendered for registration of transfer or exchange and where
notices and demands to or upon the Company or any Guarantor in respect of the
Notes, the Guarantees and this Indenture may be served. The office of the
Trustee shall be such office or agency of the Company, unless the Company shall
designate and maintain some other office or agency for one or more of such
purposes.  The Company will give prompt written notice to the Trustee of any
change in the location of any such office or agency.  If at any time the Company

furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the Corporate Trust Office, and the
Company hereby appoints the Trustee as its agent to receive all such
presentations, surrenders, notices and demands.

          The Company may also from time to time designate one or more other

the Guarantees may be presented or surrendered for any or all such purposes, and
may from time to time rescind such designation; provided, however, that no such

designation or rescission shall in any manner relieve the Company of its
obligation to maintain an office or agency in the Borough of Manhattan in The
City of New York for such purposes.  The Company will give prompt written notice
to the Trustee of any such designation or rescission and any change in the
location of any such other office or agency.

          Section 10.03. Money for Note Payments To Be Held in Trust.
                         ------------------------------------------- 

          If the Company shall at any time act as its own Paying Agent, the
Company will, on or before each due date of the principal of, premium, if any,
or interest on any of the Notes, segregate and hold in trust for the benefit of
the Holders entitled thereto a sum sufficient to pay the principal, premium, if
any, or interest so becoming due until such sums shall be paid to such Persons
or otherwise disposed of as herein provided, and will promptly notify the
Trustee of its action or failure so to act.

          If the Company is not acting as Paying Agent, the Company will, on or
before each due date of the principal of, premium, if any, or interest on any
Notes, deposit with a Paying Agent a sum in same day funds sufficient to pay the
principal, premium, if any, or interest so becoming due, such sum to be held in
trust for the benefit of the Holders entitled to such principal, premium or
interest, and (unless such Paying Agent is the Trustee) the Company will
promptly notify the Trustee of such action or any failure so to act.

          If the Company is not acting as Paying Agent, the Company will cause
each Paying Agent other than the Trustee to execute and deliver to the Trustee
an instrument in which such Paying Agent shall agree with the Trustee, subject
to the provisions of this Section 10.03, that such Paying Agent will:

          (a) hold all sums held by it for the payment of the principal of,
     premium, if any, or interest on Notes in trust for the benefit of the
     Holders entitled thereto until such sums shall be paid to such Holders or
     otherwise disposed of as herein provided;

          (b) give the Trustee notice of any Default by the Company (or any
     other obligor upon the Notes) in the making of any payment of principal of,
     premium, if any, or interest on the Notes;

          (c) at any time during the continuance of any such Default, upon the
     written request of the Trustee, forthwith pay to the Trustee all sums so
     held in trust by such Paying Agent; and
<PAGE>
 
                                     -54-

          (d) acknowledge, accept and agree to comply in all respects with the
     provisions of this Indenture relating to the duties, rights and liabilities
     of such Paying Agent.

          The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
direct any Paying Agent to pay, to the Trustee all sums held in trust by the
Company or such Paying Agent, such sums to be held by the Trustee upon the same
trusts as those upon which such sums were held by the Company or such Paying
Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying
Agent shall be released from all further liability with respect to such money.

          Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of, premium, if any,
or interest on any Note and remaining unclaimed for two years after such
principal, premium, if any, or interest has become due and payable shall be paid
to the Company upon receipt of a Company Request therefor, or (if then held by
the Company) shall be discharged from such trust; and the Holder of such Note
shall thereafter, as an unsecured general creditor, look only to the Company for
payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money, and all liability of the Company as trustee
thereof, shall thereupon cease; provided, however, that the Trustee or such
Paying Agent, before being required to make any such repayment, shall at the
expense of the Company cause to be published once, in The New York Times and The
Wall Street Journal (national edition), notice that such money remains unclaimed
and that, after a date specified therein, which shall not be less than 30 days
from the date of such notification or publication, any unclaimed balance of such
money then remaining will be repaid to the Company.

          Section 10.04. Existence.
                         --------- 

          Subject to Article Eight, each of the Company and each Guarantor will
do or cause to be done all things necessary to and will cause each of its
Restricted Subsidiaries to preserve and keep in full force and effect its
corporate existence and the corporate existence of each of the Restricted
Subsidiaries, and the rights (charter and statutory), licenses and franchises of
the Company and each of the Restricted Subsidiaries; provided, however, that the
Company shall not be required to preserve any such right, license or franchise
if the Board of Directors shall determine that the preservation thereof is no
longer desirable in the conduct of the business of the Company, the Guarantors
and their respective Restricted Subsidiaries as a whole and that the loss
thereof is not disadvantageous in any material respect to the Holders; provided,
further, however, that the foregoing shall not prohibit a sale, transfer or
conveyance of a Subsidiary of the Company or any of its assets or Capital Stock
in compliance with the terms of this Indenture.

          Section 10.05. Payment of Taxes and Other Claims.
                         ---------------------------------

paid or discharged, before the same shall become delinquent, (a) all taxes,
assessments and governmental charges levied or imposed (i) upon the Company or
any of its Restricted Subsidiaries or (ii) upon the income, profits or property
of the Company or any of its Restricted Subsidiaries and (b) all material lawful
claims for labor, materials and supplies, which, if unpaid, might by law become
a Lien upon the property of the Company or any of its Restricted Subsidiaries;
provided, however, that the Company shall not be required to pay or discharge or
cause to be paid or discharged any such tax, assessment, charge or claim whose
amount, applicability or validity is being contested in good faith by
appropriate proceedings properly instituted and diligently conducted.

                         ------------------------- 

          The Company and each Guarantor shall, and shall cause each of their
respective Restricted Subsidiaries to, cause all material properties owned by
the Company or the Restricted Subsidiaries or used or held for use in the
conduct of its business or the business of the Restricted Subsidiaries to be
maintained and kept in good condition, repair and working order (reasonable wear
and tear excepted) and supplied with all necessary equipment and will cause to
be made all repairs, renewals, replacements, betterments and improvements
thereof, all as shall be reasonably necessary so that the business carried on in
connection therewith may be conducted at all times in the ordinary course;
provided, however, that nothing in this Section 10.06 shall prevent the Company,
any Guarantor or any of their respective Subsidiaries from discontinuing the
operation and maintenance of any of such properties if (x) such discontinuance
is, in the judgment of the Company, the Guarantor, or the Restricted Subsidiary,
desirable in the conduct of its businesses or (y) if such discontinuance or
disposal is not materially adverse to either the Company, the Guarantors and
their respective Restricted Subsidiaries taken as a whole or the ability of the
Company and the Guarantors taken as a whole to otherwise satisfy its obligations
hereunder.

          Section 10.07. Insurance.
                         --------- 

          The Company will at all times keep all of its and the Restricted
Subsidiaries' properties which are of an insurable nature insured with insurers,
believed by the Company in good faith to be financially sound and responsible,
against loss or damage to the extent that property of similar character is
usually so insured by corporations similarly situated and owning like properties
(which may include self-insurance, if reasonable and in comparable form to that
maintained by companies similarly situated) except where the failure to do so
could not reasonably be expected to have a material adverse effect on the
condition (financial or otherwise), earnings, business affairs or prospects of
the Company and the Restricted Subsidiaries, taken as a whole.

          Section 10.08. Compliance Certificate.
                         ---------------------- 

          (a) The Company will deliver to the Trustee within 120 days after the
end of each of the Company's fiscal years a certificate to the Trustee at least
annually from the chief financial officer (or if the Company does not have a
chief financial officer, the Company's principal executive, financial or
accounting officer) of the Company as to his or her knowledge of the compliance
of the Company, the Guarantors and the Restricted Subsidiaries with all
conditions and covenants under this Indenture and any related documents and
whether any Default or Event of Default has occurred, such compliance to be
determined without regard to any period of grace or requirement of notice
provided herein.

          (b) The Company will deliver to the Trustee as soon as possible, and
in any event within 10 days after the Company becomes aware of the occurrence of
any Default or Event of Default, an Officers' Certificate specifying such
Default or Event of Default and what action the Company or the applicable

required to file with the Commission pursuant to Sections 13(a) and 15(d) of the

                                     -56-

Trustee copies of such reports and documents; provided, however, that if the

          Section 10.10. Limitation on Guarantees by Restricted Subsidiaries.
                         --------------------------------------------------- 

          The Company shall not cause or permit any of the Domestic
Subsidiaries, directly or indirectly, to guarantee the payment of any
Indebtedness of the Company or any Restricted Subsidiary unless such Domestic
Subsidiary (A) is a Guarantor or (B) simultaneously executes and delivers a
supplemental indenture to this Indenture pursuant to which it will become a
Guarantor on the basis provided for in Article Thirteen of this Indenture.
Notwithstanding the foregoing, any Note Guarantee by a Restricted Subsidiary
shall be automatically and unconditionally released and discharged upon any
sale, exchange or transfer, to any Person not an Affiliate of the Company, of
all of the Capital Stock of such Restricted Subsidiary, or all or substantially
all the assets of such Restricted Subsidiary, pursuant to a transaction which is
in compliance with this Indenture. The Company may, at any time, cause a
Restricted Subsidiary to become a Guarantor by executing and delivering a
supplemental indenture providing for the guarantee of payment of the Notes by
such Restricted Subsidiary on the basis provided in this Indenture.

          Section 10.11. Limitation on Indebtedness.
                         --------------------------

contingently or otherwise (in each case, to "incur"), the payment of any
Indebtedness (including any Acquired Indebtedness); provided, however, that (i)
the Company and any Guarantor may incur Indebtedness (including Acquired
Indebtedness) and (ii) a Restricted Subsidiary may incur Acquired Indebtedness,
in each case if immediately after giving pro forma effect thereto, the
Consolidated Fixed Charge Coverage Ratio of the Company and its Restricted
Subsidiaries is at least equal to 2.0:1.0.

          (b) Notwithstanding the foregoing, the Company and, to the extent

     Subsidiary and surety bonds provided by the Company or any Restricted
     Subsidiary in the ordinary course of business;

            (v) Indebtedness of any Restricted Subsidiary owed to and held by
     the Company or any Restricted Subsidiary, and Indebtedness of the Company
     owed to and held by any other Restricted Subsidiary which is unsecured and
     subordinated in right of payment to the payment and performance of the

     Rate Protection Obligations does not exceed the principal amount of the
     Indebtedness to which such Interest Rate Protection Obligations relate;

         (viii) Indebtedness of the Company in respect of Purchase Money
     Indebtedness in an amount not exceeding $2.0 million incurred in any one

     Restricted Subsidiary and/or (b) obligations to purchase or sell assets or
     properties, in each case, incurred in the ordinary course of business of
     the Company or any Restricted Subsidiary; provided, however, that such
     Currency Agreements do not increase the Indebtedness or other obligations
     of the Company and its Restricted Subsidiaries outstanding other than as a
     result of fluctuations in foreign currency exchange rates or by reason of
     fees, indemnities and compensation payable thereunder;

            (x) (a) Indebtedness of the Company or any Guarantor to the extent
     the proceeds thereof are used to Refinance Indebtedness of the Company or
     any Guarantor or any Restricted Subsidiary and (b) Indebtedness of any
     Restricted Subsidiary that is not a Guarantor to the extent the proceeds
     thereof are used to Refinance Indebtedness of any Restricted Subsidiary

     Refinanced as described under "Use of Proceeds" in the Offering Memorandum
     and Indebtedness incurred under clause (i) or (v) above; provided, however,
     that, in the case of either clause (a) or (b), (1) the principal amount of
     Indebtedness incurred pursuant to this clause (x) (or, if such Indebtedness
     provides for an amount less than the principal amount thereof to be due and
     payable upon a declaration of acceleration of the maturity thereof, the
     original issue price of such Indebtedness) shall not exceed the sum of (A)

     issuance date of such Indebtedness), plus (B) the amount of any premium
     required to be paid in connection with such Refinancing pursuant to the
     terms of such Indebtedness or the amount of any premium reasonably
     determined by the Company or a Restricted Subsidiary, as applicable, as
     necessary to accomplish such Refinancing by means of a tender offer or

            (i) declare or pay any dividend or make any other distribution or
     payment on or in respect of Capital Stock of the Company or any Restricted
     Subsidiary or any payment made to the direct or indirect Holders (in their
     capacities as such) of Capital Stock of the Company or any Restricted
     Subsidiary (other than dividends or distributions made to the Company or a
     Restricted Subsidiary and dividends and distributions payable solely in
     Capital Stock of the Company (other than Redeemable Capital Stock) or in
     rights to purchase Capital Stock of the Company (other than Redeemable
     Capital Stock)); or

           (ii) purchase, redeem, defease or otherwise acquire or retire for
     value any Capital Stock of the Company or any Restricted Subsidiary (other

           (iv) make any Investment (other than a Permitted Investment) in any
     Person (such payments or Investments described in clauses (i), (ii), (iii)
     and (iv) are collectively referred to as "Restricted Payments"), unless, at
     the time of and after giving effect to the proposed Restricted Payment (the
     amount of any such Restricted Payment, if other than in cash, being the
     Fair Market Value of the asset(s) proposed to be transferred by the Company
     or such Restricted Subsidiary, as the case may be, pursuant to such
     Restricted Payment):

                (A) no Default shall have occurred and be continuing;

                                     -59-

                (B) the Company could incur $1.00 of additional Indebtedness by
          virtue of the Consolidated Fixed Charge Coverage Ratio set forth in
          Section 10.11(a); and

                (C) the aggregate amount of all Restricted Payments declared or
          made (and not repaid or reimbursed) from and after the Issue Date
          would not exceed the sum of (1) 50% of cumulative Consolidated Net
          Income of the Company during the period (treated as one accounting
          period) beginning on the first day of the fiscal quarter that includes
          the Issue Date and ending on the last day of the fiscal quarter of the
          Company immediately preceding the date of such proposed Restricted
          Payment for which consolidated financial information of the Company is
          internally available (or, if such cumulative Consolidated Net Income
          of the Company for such period shall be a deficit, minus 100% of such
          deficit), plus (2) the aggregate net cash proceeds received by the
          Company either (x) as capital contributions in the form of common
          equity to the Company after the Issue Date or (y) from the issuance or
          sale of Capital Stock (excluding Redeemable Capital Stock and Capital
          Stock to the extent the proceeds from the sale thereof are used to
          redeem Notes but including Capital Stock issued upon the conversion of
          convertible Indebtedness, in exchange for outstanding Indebtedness or
          from the exercise of options, warrants or rights to purchase Capital
          Stock (other than Redeemable Capital Stock)) of the Company to any
          Person (other than to a Restricted Subsidiary of the Company) after
          the Issue Date (excluding the net cash proceeds from any issuance and
          sale of Capital Stock financed using funds borrowed from the Company
          or any Restricted Subsidiary until and to the extent such borrowing is
          repaid), plus (3) in the case of the disposition or repayment of any
          Investment constituting a Restricted Payment made after the Issue
          Date, an amount equal to the lesser of the return of capital with
          respect to such Investment and the initial amount of such Investment
          which was treated as a Restricted Payment, in either case, less the
          cost of the disposition of such Investment.

          For purposes of the preceding clause (C)(2), upon the issuance of
Capital Stock either from the conversion of convertible Indebtedness or exchange
for outstanding Indebtedness or upon the exercise of options, warrants or
rights, the amount counted as net cash proceeds received will be the cash amount
received by the Company at the original issuance of the Indebtedness that is so
converted or exchanged or from the issuance of options, warrants or rights, as
the case may be, plus the incremental amount of cash received by the Company, if

          Section 10.13.   Limitation on Transactions with Affiliates.
                           ------------------------------------------ 

          The Company shall not, and shall not cause or permit any of the
Restricted Subsidiaries, directly or indirectly, to, conduct any business or
enter into or suffer to exist any transaction or series of related transactions
with, or for the benefit of, any of their respective Affiliates (other than a
Restricted Subsidiary so long as no Affiliate of the Company or any beneficial
holder of 5% or more of any class or series of Capital Stock of the Company
shall beneficially own any Capital Stock in such Restricted Subsidiary) or any
beneficial holder of 10% or more of any class of Capital Stock of the Company or
any officer or director of the Company or any Restricted Subsidiary (each, an
"Affiliate Transaction"), unless (i) such Affiliate Transaction is on terms that
are no less favorable to the Company or the Restricted Subsidiary, as the case
may be, than those which could have been obtained in a comparable transaction at
such time from Persons who do not have such a relationship, (ii) with respect to
any Affiliate Transaction or series of Affiliate Transactions involving
aggregate payments or value equal to or greater than $2.0 million, the Company
shall have delivered an officers' certificate to the Trustee certifying that
such Affiliate Transaction or series of Affiliate Transactions has been approved
by a majority of the Board of Directors of the Company, including a majority of
the disinterested directors, if any, of the Board of Directors of the Company,
and (iii) with respect to any Affiliate Transaction or series of Affiliate
Transactions involving aggregate payments or value equal to or greater than $5.0
million (or greater than $2.0 million in the event there are no disinterested
directors), the Company shall have obtained a written opinion from an
Independent Financial Advisor stating that the terms of such Affiliate
Transaction or series of Affiliate Transactions are fair, from a financial point
of view, to the Company or the Restricted Subsidiary involved, as the case may
be.

          Notwithstanding the foregoing, the restrictions set forth in this
Section 10.13 shall not apply to (i) transactions with or among the Company and
the Restricted Subsidiaries; (ii) directors' fees, indemnification and similar
arrangements, consulting fees, employee salaries, bonuses or employment
agreements, compensation or employee benefit arrangements and incentive
arrangements with any officer, director or employee of the Company or any

compliance with the provisions described in Section 10.12; (v) loans and

in an aggregate amount not in excess of $2.5 million in any fiscal year; and
(vi) the incurrence of intercompany Indebtedness permitted pursuant to clause
(v) of Section 10.11(b).

          Section 10.14.   Disposition of Proceeds of Asset Sales.
                           -------------------------------------- 

          The Company shall not, and shall not cause or permit any Restricted
Subsidiary, directly or indirectly, to, make any Asset Sale, unless (i) the
Company or such Restricted Subsidiary, as the case may be, receives
consideration at the time of such Asset Sale at least equal to the Fair Market
Value of the assets sold or otherwise disposed of and (ii) at least 75% of such
consideration consists of (A) cash or Cash Equivalents, (B) properties and
capital assets to be used in the same line of business being conducted by the
Company or any Restricted Subsidiary at such time or (C) Capital Stock in any
Person which thereby becomes a Restricted Subsidiary whose assets consist
primarily of properties and capital assets used in the same line of business
being conducted by the Company or any Restricted Subsidiary at such time. The
amount of any (i) Indebtedness (other than any Subordinated Indebtedness) of the
Company or any Restricted Subsidiary actually assumed by the transferee in such
Asset Sale and from which the Company and the Restricted Subsidiaries are fully
released and (ii) notes or other similar obligations received by the Company or
the Restricted Subsidiaries from such transferee that are immediately converted,
sold or exchanged (or are converted, sold or exchanged within thirty days of the
related Asset Sale) by the Company or the Restricted Subsidiaries into cash, in
an amount equal to the net cash proceeds realized upon such conversion, sale or
exchange, shall be deemed to be cash for purposes of determining the percentage
of cash or Cash Equivalent consideration received by the Company or the
Restricted Subsidiaries.

          The Company or such Restricted Subsidiary, as the case may be,
may (i) apply the Net Cash Proceeds of any Asset Sale within 365 days of receipt
thereof to permanently repay Senior Indebtedness or Indebtedness (for purposes
of this clause, a repayment of any amount owing under a revolving credit
facility shall be deemed a permanent repayment to the extent the amount
represented by such repayment is not drawn upon by the Company for a period of
six months after such repayment) of any Restricted Subsidiary that is not
subordinated in right of payment to any Indebtedness of such Restricted
Subsidiary, provided no such repayment shall affect the amount permitted under
clause (i) of Section 10.11(b) or (ii) commit in writing within 365 days after
the receipt thereof to acquire, construct or improve properties and capital
assets to be used in the same line of business as being conducted by the Company
or any Restricted Subsidiary at such time and so apply such Net Cash Proceeds
within 365 days after the receipt thereof.

          To the extent all or part of the Net Cash Proceeds of any Asset
Sale are not applied (or, in the case of clause (ii) of the immediately
preceding paragraph, committed to be so applied in writing) within 365 days of
such Asset Sale as described in clause (i) or (ii) of the immediately preceding
paragraph (such Net Cash Proceeds, the "Unutilized Net Cash Proceeds"), the
Company shall, within 20 business days after such 365th day, make an offer to
purchase (the "Asset Sale Offer") to all Holders of outstanding Notes up to a
maximum principal amount (expressed as a multiple of $1,000) of Notes equal to
such Unutilized Net Cash Proceeds, at a purchase price in cash equal to 100% of
the principal amount thereof, plus accrued and unpaid interest thereon, if any,
to the date of such purchase; provided, however, that the Asset Sale Offer shall
not be required to be made until there are aggregate Unutilized Net Cash
Proceeds equal to or in excess of $7.5 million, at which time the entire amount 
of such Unutilized Net Cash Proceds, and not just the amount in excess

<PAGE>
 
                                     -63-

of $7.5 million, shall be applied as required pursuant to this paragraph. An
Asset Sale Offer will be required to be kept open for a period of at least 20
business days after commencement thereof.

          Notice of an Asset Sale Offer shall be prepared and mailed by the
Company with a copy to the Trustee not later than the 20th business day after
the Company is obligated to make an Asset Sale Offer (in accordance with the
immediately preceding paragraph) to each Holder at such Holder's registered
address, stating:

          (i)    that the Company is offering to purchase the maximum principal
     amount of Notes that may be purchased out of the Unutilized Net Cash
     Proceeds to the extent to be applied to an offer to purchase Notes (as
     provided in the immediately preceding paragraph), at an offer price in cash
     in an amount equal to 100% of the principal amount thereof, plus accrued
     and unpaid interest, if any, to the date of the purchase (the "Asset Sale
     Offer Purchase Date"), which shall be a Business Day, specified in such
     notice, that is not earlier than 20 days or later than 60 days from the
     date such notice is mailed;

          (ii)   the amount of accrued and unpaid interest, if any, as of
     the Asset Sale Offer Purchase Date;

         (iii)   that any Note not tendered will continue to accrue interest in
     accordance with the terms thereof;

          (iv)   that, unless the Company defaults in the payment of the
     purchase price for the Notes payable pursuant to the Asset Sale Offer, any
     Notes accepted for payment pursuant to the Asset Sale Offer shall cease to
     accrue interest after the Asset Sale Offer Purchase Date;

           (v)   that Holders electing to have Notes purchased pursuant to
     an Asset Sale Offer will be required to surrender their Notes to the Paying
     Agent at the address specified in the notice prior to 5:00 p.m., New York
     City time, on the third Business Day prior to the Asset Sale Purchase Date
     with the "Option of Holder to Elect Purchase" on the reverse thereof
     completed and must complete any form letter of transmittal proposed by the
     Company (which letter must be completed correctly by such Holder) and which
     is acceptable to the Trustee and the Paying Agent;

          (vi)   that Holders of Notes will be entitled to withdraw their
     election if the Paying Agent receives, not later than 5:00 p.m., New York
     City time, on the third Business Day prior to the Asset Sale Offer Purchase
     Date, a telegram, telex, facsimile transmission or letter setting forth the
     name of the Holder, the principal amount of Notes the Holder delivered for
     purchase, the Note certificate number (if any) and a statement that such
     Holder is withdrawing its election to have such Notes purchased;

         (vii)   that Holders whose Notes are purchased only in part will be
     issued Notes equal in principal amount to the unpurchased portion of the
     Notes surrendered;

        (viii)   the instructions that Holders must follow in order to tender
     their Notes; and

          (ix)   information concerning the business of the Company, the most
     recent annual and quarterly reports of the Company filed with the SEC
     pursuant to the Exchange Act (or, if the Company is not then required to
     file any such reports with the SEC, the comparable reports prepared

     Company's business, information with respect to pro forma historical
     financial information after giving effect to such Asset Sale and such other
     information concerning the circumstances and relevant facts regarding such
     Asset Sale and Asset Sale Offer as would be material to a Holder of Notes
     in connection with the decision of such Holder as to whether or not it
     should tender Notes pursuant to the Asset Sale Offer.

          With respect to any Asset Sale Offer effected pursuant to this Section
10.14, to the extent the aggregate principal amount of Notes tendered pursuant
to such Asset Sale Offer exceeds the Unutilized Net Cash Proceeds to be applied
to the repurchase thereof, such Notes shall be purchased pro rata based on the
aggregate principal amount of such Notes tendered by each Holder. To the extent
the Unutilized Net Cash Proceeds exceed the aggregate amount of Notes tendered
by the Holders pursuant to such Asset Sale Offer, the Company may retain and
utilize any portion of the Unutilized Net Cash Proceeds not applied to
repurchase the Notes for any purpose consistent with the other terms of this
Indenture.

          The Company shall comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act, and any other applicable
securities laws or regulations and any applicable requirements of any securities
exchange on which the Notes are listed, and any violation of the provisions of
this Indenture relating to such Asset Sale Offer occurring as a result of such
compliance shall not be deemed a Default.

          Section 10.15.   Change of Control.
                           ----------------- 

          Following the occurrence of a Change of Control (the date of such
occurrence being the "Change of Control Date"), the Company shall be
obligated, not more than 40 or less than 20 business days after the Change of
Control Date, to make an offer to purchase (a "Change of Control Offer") all
of the then Outstanding Notes at a purchase price (the "Change of Control
Purchase Price") in cash equal to 101% of the principal amount thereof, plus
accrued and unpaid interest thereon, if any, to the purchase date. The Company
will be required to purchase all Notes properly tendered into the Change of
Control Offer and not withdrawn.

          In order to effect such Change of Control Offer, the Company shall,
not later than the 40th business day after the Change of Control Date, be
obligated to mail to each Holder of Notes notice of the Change of Control Offer,
which notice will govern the terms of the Change of Control Offer.  The Change
of Control Offer will be required to be kept open for a period of at least 20
business days.  The notice of the Change of Control Offer shall state:

          (a)  that the Change of Control has occurred and that such Holder has
     the right to require the Company to purchase all or a portion (equal to
     $1,000 or an integral multiple thereof) of such Holder's Notes at a
     purchase price in cash equal to 101% of the aggregate principal amount
     thereof, plus accrued and unpaid interest, if any, to the date of purchase,
     which shall be a Business Day, specified in such notice, that is not more
     than 40 or less than 20 business days after the Change of Control Date (the
     "Change of Control Purchase Date");

          (b)  the amount of accrued and unpaid interest, if any, as of the
     Change Control Purchase Date;

          (c)  that any Note not tendered for payment will continue to accrue
     interest in accordance with the terms thereof;
<PAGE>
 
                                     -65-

          (d)  that, unless the Company defaults in the payment of the purchase
     price for the Notes payable pursuant to the Change of Control Offer, any
     Notes accepted for payment pursuant to the Change of Control Offer shall
     cease to accrue interest after the Change of Control Purchase Date;

          (e)  that Holders electing to have Notes purchased pursuant to a
     Change of Control Offer will be required to surrender their Notes to the
     Paying Agent at the address specified in the notice prior to 5:00 p.m., New
     York City time, on the third Business Day prior to the Change of Control
     Purchase Date with the "Option of Holder to Elect Purchase" on the reverse
     thereof completed and must complete any form letter of transmittal proposed
     by the Company and be completed correctly by such Holder and be acceptable
     to the Trustee and the Paying Agent;

          (f)  that Holders of Notes will be entitled to withdraw their election
     if the Paying Agent receives, not later than 5:00 p.m., New York City time,
     on the third Business Day prior to the Change of Control Purchase Date, a
     telegram, telex, facsimile transmission or letter setting forth the name of
     the Holder, the principal amount of Notes the Holder delivered for
     purchase, the Note certificate number (if any) and a statement that such
     Holder is withdrawing its election to have such Notes purchased;

          (g)  that Holders whose Notes are purchased only in part will be
     issued Notes equal in principal amount to the unpurchased portion of the
     Notes surrendered; and

          (h)  the instructions that Holders must follow in order to tender
     their Notes.

          On the Change of Control Purchase Date, the Company will (i) accept
for payment all Notes or portions thereof tendered pursuant to the Change of
Control Offer, (ii) deposit with the Paying Agent an amount in cash equal to the
aggregate purchase price of all Notes or portions thereof accepted for payment,
plus any accrued and unpaid interest on such Notes as of the Change of Control
Purchase Date, and (iii) deliver or cause to be delivered to the Trustee all
Notes tendered pursuant to the Change of Control Offer.  The Paying Agent shall
as promptly as practicable after the Change of Control Purchase Date mail to
each Holder of Notes or portions thereof accepted for payment an amount in cash
equal to the purchase price for such Notes, plus any accrued and unpaid interest
thereon, and the Trustee shall promptly authenticate and mail to such Holders of
Notes accepted for payment in part a new Note equal in principal amount to any
unpurchased portion of the Note surrendered.  Any Notes not so accepted in whole
or in part shall be promptly returned to the Holder thereof.

          On and after a Change of Control Purchase Date, interest will cease to
accrue on the Notes or portions thereof accepted for payment unless the Company
defaults in the payment of the purchase price therefor.  The Company will
publicly announce the results of the Change of Control Offer as soon as
practicable after the Change of Control Purchase Date.

          The Company shall comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act, and any other applicable
securities laws or regulations and any applicable requirements of any securities
exchange on which the Notes are listed, in connection with the repurchase of
Notes pursuant to a Change of Control Offer, and any violation of the provisions
of this Indenture relating to such Change of Control Offer occurring as a result
of such compliance shall not be deemed a Default.

than a Guarantor) as an "Unrestricted Subsidiary" under this Indenture (a
"Designation") only if:

           (i)    no Default shall have occurred and be continuing at the time
     of or after giving effect to such Designation;

          (ii)    the Company would be permitted to make an Investment at the
     time of Designation (assuming the effectiveness of such Designation) in an
     amount (the "Designation Amount") equal to the Fair Market Value of the
     Company's interest in such Subsidiary on such date; and

         (iii)    the Company would be permitted under this Indenture to incur
     $1.00 of additional Indebtedness (other than Permitted Indebtedness)
     pursuant to Section 10.11 at the time of such Designation (assuming the
     effectiveness of such Designation).

          In the event of any such Designation, the Company shall be deemed to
have made an Investment constituting a Restricted Payment pursuant to Section
10.12 for all purposes of this Indenture in the Designation Amount.

          The Company may revoke any Designation of a Subsidiary as an
Unrestricted Subsidiary (a "Revocation") if:

          (i)     no Default shall have occurred and be continuing at the time
     of and after giving effect to such Revocation; and

         (ii)     all Liens and Indebtedness of such Unrestricted Subsidiary
     outstanding immediately following such Revocation would, if incurred at
     such time, have been permitted to be incurred for all purposes of this
     Indenture.

          All Designations and Revocations must be evidenced by Board
Resolutions of the Company delivered to the Trustee certifying compliance with
the foregoing provisions.

          Section 10.20.   Limitation on Other Senior Subordinated Indebtedness.
                           ---------------------------------------------------- 

          Neither the Company nor any Guarantor shall create, incur, assume,
guarantee or in any other manner become liable with respect to any Indebtedness
(other than the Notes and the Note Guarantees) subordinate in right of payment
to any Indebtedness of the Company or of such Guarantor, as the case may be,
unless such Indebtedness is either (i) pari passu in right of payment with the
Notes or such Note Guarantee, as the case may be, or (ii) subordinate in right
of payment to the Notes or such Note Guarantee, as the case may be, in the same
manner and at least to the same extent as the Notes are subordinated to Senior
Indebtedness or as such Note Guarantee is subordinated to Guarantor Senior
Indebtedness, as the case may be.

          Optional Redemption upon Equity Offering.  On or prior to November 1,
          ----------------------------------------                             
2000, the Company may, at its option, use the net proceeds of an Equity Offering
to redeem up to 35% of the originally issued aggregate principal amount of the
Notes, at a redemption price in cash equal to 110 1/4% of the principal amount
thereof, plus accrued and unpaid interest thereon, if any, to the date of
redemption; provided, however, that not less than $65.0 million in aggregate
principal amount of Notes is outstanding following such redemption. Notice of
any such redemption must be given not later than 60 days after the consummation
of the Equity Offering.

          As used in the preceding paragraph, an "Equity Offering" means any
public or private sale of equity securities (other than Redeemable Capital
Stock) of the Company; provided, however, that the proceeds (net of any
underwriting discounts or commissions) to the Company from any such private sale
of equity securities shall be at least $20.0 million.

          The election of the Company to redeem any Notes pursuant to Section
11.01(a) shall be evidenced by a Board Resolution of the Company and an
Officers' Certificate.  In case of any redemption at the election of the
Company, the Company shall, at least 60 days prior to the Redemption Date fixed
by the Company (unless a shorter notice period shall be satisfactory to the
Trustee), notify the Trustee in writing of such Redemption Date and of the
principal amount of Notes to be redeemed.

          Section 11.04.   Selection of Notes To Be Redeemed.
                           --------------------------------- 

          In the event that less than all of the Notes are to be redeemed at any
time, selection of Notes for redemption shall be made by the Trustee in
compliance with the requirements of the principal national securities exchange,
if any, on which the Notes are listed or, if the Notes are not listed on a
national securities exchange, on a pro rata basis, by lot or by such other
method as the Trustee deems fair and appropriate; provided, however, that no
Notes of a principal amount of $1,000 or less shall be redeemed in part;
provided, further, however, that any such redemption made with the net proceeds
of an Equity Offering shall be made on a pro rata basis or on as nearly a pro
rata basis as practicable (subject to the procedures of the Depositary).  Notice
of redemption will be mailed by first class mail at least 30 but not more than
60 days before the redemption date to each holder of Notes to be redeemed at its
registered address.  If any Note is to be redeemed in part only, the notice of
redemption that relates to such Note will state the portion of the principal
amount thereof to be redeemed.  A new Note in a principal amount equal to the
unredeemed portion thereof will be issued in the name of the holder thereof upon
cancellation of the original Note.  On and after the redemption date, interest
will cease to accrue on Notes or portions thereof called for redemption so long
as the Company has deposited with the paying agent for the Notes funds in
satisfaction of the applicable redemption price pursuant to this Indenture.

          Section 11.05.   Notice of Redemption.
                           -------------------- 

          Notice of any optional or mandatory redemption shall be mailed by
first-class mail, postage prepaid, mailed at least 30 but not more than 60 days
before the Redemption Date, to each Holder of Notes to be redeemed at its
registered address.

          All notices of redemption shall state:

          (a)  the Redemption Date;

          (b)  the Redemption Price;

          (c)  if fewer than all outstanding Notes are to be redeemed, the
     identification of the particular Notes to be redeemed;

          (d)  in the case of a Note to be redeemed in part, the principal
     amount of such Note to be redeemed and that after the Redemption Date upon
     surrender of such Note, a new Note or Notes in the aggregate principal
     amount equal to the unredeemed portion thereof will be issued;

          (e)  that Notes called for redemption must be surrendered to the
     Paying Agent to collect the Redemption Price;

          (f)  that on the Redemption Date the Redemption Price will become due
     and payable upon each such Note or portion thereof, and that (unless the
     Company shall default in payment of the Redemption Price) interest thereon
     shall cease to accrue on and after said date;

          (g)  the place or places where such Notes are to be surrendered for
     payment of the Redemption Price;

          (h)  the CUSIP number, if any, relating to such Notes; and
<PAGE>

                                     -70-
 
          (i)  the paragraph of the Notes pursuant to which the Notes are being
     redeemed.

          Notice of redemption of Notes to be redeemed shall be given by the
Company or, at the Company's written request, by the Trustee in the name and at
the expense of the Company.

          The notice if mailed in the manner herein provided shall be
conclusively presumed to have been given, whether or not the Holder receives
such notice.  In any case, failure to give such notice by mail or any defect in
the notice to the Holder of any Note designated for redemption as a whole or in
part shall not affect the validity of the proceedings for the redemption of any
other Note.

          Section 11.06.   Deposit of Redemption Price.
                           --------------------------- 

          On or prior to 10:00 a.m., New York City time, on each Redemption
Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if
the Company is acting as its own Paying Agent, segregate and hold in trust as
provided in Section 10.03) an amount of money in same day funds sufficient to
pay the Redemption Price of, and accrued interest on, all the Notes or portions
thereof which are to be redeemed on that date.

          Section 11.07.   Notes Payable on Redemption Date.
                           -------------------------------- 

          Notice of redemption having been given as aforesaid, the Notes so to
be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified and from and after such date (unless the
Company shall default in the payment of the Redemption Price) such Notes shall
cease to bear interest.  Upon surrender of any such Note for redemption in
accordance with said notice, such Note shall be paid by the Company at the
Redemption Price; provided, however, that installments of interest whose Stated
Maturity is on or prior to the Redemption Date shall be payable to the Holders
of such Notes, or one or more predecessor Notes, registered as such on the
relevant Regular Record Dates according to the terms and the provisions of
Section 3.06.

          On and after any Redemption Date, if money sufficient to pay the
Redemption Price of and accrued interest on Notes called for redemption shall
have been made available in accordance with Section 11.06, the Notes called for
redemption will cease to accrue interest and the only right of the Holders of
such Notes will be to receive payment of the Redemption Price of and subject to
the provision in the preceding paragraph, accrued and unpaid interest on such
Notes to the Redemption Date.  If any Note called for redemption shall not be so
paid upon surrender thereof for redemption, the principal and premium, if any,
shall, until paid, bear interest from the Redemption Date at the rate then borne
by such Note.

          Section 11.08.   Notes Redeemed or Purchased in Part.
                           ----------------------------------- 

          Any Note which is to be redeemed or purchased only in part shall be
surrendered to the Paying Agent at the office or agency maintained for such
purpose pursuant to Section 10.02 (with, if the Company, the Note Registrar or
the Trustee so requires, due endorsement by, or a written instrument of transfer
in form satisfactory to, the Company, the Note Registrar or the Trustee duly
executed by the Holder thereof or such Holder's attorney duly authorized in
writing), and the Company shall execute, and the Trustee shall authenticate and
deliver to the Holder of such Note without service charge, a new Note or Notes,
of any authorized denomination as requested by such Holder in aggregate
principal amount equal to, and in exchange for, the portion of the principal of
the Note so surrendered that is not redeemed or purchased.

                          SATISFACTION AND DISCHARGE

          Section 12.01.   Satisfaction and Discharge of Indenture.
                           --------------------------------------- 

          This Indenture shall be discharged and cease to be of further effect
(except as to surviving rights or registration of transfer or exchange of Notes
herein expressly provided for) as to all outstanding Notes, and the Trustee, on
written demand of and at the expense of the Company, shall execute proper
instruments acknowledging satisfaction and discharge of this Indenture, when

          (a)  either

               (i)     all the Notes theretofor authenticated and delivered
          (except lost, stolen or destroyed Notes which have been replaced or
          paid and Notes for whose payment money has theretofor been deposited
          in trust or segregated and held in trust by the Company and thereafter
          repaid to the Company or discharged from such trust) have been
          delivered to the Trustee for cancellation or

               (ii)    all Notes not theretofor delivered to the Trustee for
          cancellation have become due and payable and the Company or any
          Guarantor has irrevocably deposited or caused to be deposited with the
          Trustee funds in an amount sufficient to pay and discharge the entire
          Indebtedness on the Notes not theretofor delivered to the Trustee for
          cancellation, for principal of, premium, if any, and interest on the
          Notes to the date of deposit together with irrevocable instructions
          from the Company directing the Trustee to apply such funds to the
          payment thereof at maturity or redemption, as the case may be;

          (b)  the Company or any Guarantor has paid all other sums payable
     under this Indenture by the Company and the Guarantors; and

          (c)  the Company and each of the Guarantors have delivered to the
     Trustee an officers' certificate and an opinion of counsel each stating
     that all conditions precedent under this Indenture relating to the
     satisfaction and discharge of this Indenture have been complied with.

          Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 6.07 and, if money shall
have been deposited with the Trustee pursuant to subclause (a)(ii) of this
Section 12.01 the obligations of the Trustee under Section 12.02, shall survive.

          Section 12.02.   Application of Trust Money.
                           -------------------------- 

          Subject to the provisions of the last paragraph of Section 10.03, all
money deposited with the Trustee pursuant to Section 12.01 shall be held in
trust and applied by it, in accordance with the provisions of the Notes and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal of, premium, if
any, and interest on the Notes for whose payment such money has been deposited
with the Trustee.

                              GUARANTEE OF NOTES

          Section 13.01.   Guarantee.
                           --------- 

          Subject to the provisions of this Article Thirteen, each Guarantor, if
any, hereby jointly and severally and fully and unconditionally guarantees to
each Holder of a Note authenticated and delivered by the Trustee and to the
Trustee and its successors and assigns, irrespective of (i) the validity and
enforceability of this Indenture, the Notes or the obligations of the Company or
any other Guarantors to the Holders or the Trustee hereunder or thereunder or
(ii) the absence of any action to enforce the same or any other circumstances
which might otherwise constitute a legal or equitable discharge or default of a
Guarantor, that:  (a) the principal of, premium, if any, and interest on the
Notes will be duly and punctually paid in full when due, whether at maturity, by
acceleration or otherwise, and interest on the overdue principal and (to the
extent permitted by law) interest, if any, on the Notes and all other
obligations of the Company or the Guarantors to the Holders or the Trustee
hereunder or thereunder (including fees, expenses or other) and all other
Obligations on the Notes will be promptly paid in full or performed, all in
accordance with the terms hereof and thereof; and (b) in case of any extension
of time of payment or renewal of any Notes or any of such other Obligations with
respect to the Notes, the same will be promptly paid in full when due or
performed in accordance with the terms of the extension or renewal, whether at
Stated Maturity, by acceleration or otherwise.  Failing payment when due of any
amount so guaranteed, or failing performance of any other obligation of the
Company to the Holders, for whatever reason, each Guarantor will be obligated to
pay, or to perform or cause the performance of, the same immediately.  An Event
of Default under this Indenture or the Notes shall constitute an event of
default under this Guarantee, and shall entitle the Holders to accelerate the
obligations of the Guarantors hereunder in the same manner and to the same
extent as the obligations of the Company.

          Each of the Guarantors, if any, hereby agrees that its obligations
hereunder shall be unconditional, irrespective of the validity, regularity or
enforceability of the Notes or this Indenture, the absence of any action to
enforce the same, any waiver or consent by any Holder of the Notes with respect
to any provisions hereof or thereof, any release of any other Guarantor, the
recovery of any judgment against the Company, any action to enforce the same,
whether or not a Guarantee is affixed to any particular Note, or any other
circumstance which might otherwise constitute a legal or equitable discharge or
defense of a guarantor.  Each of the Guarantors hereby waives the benefit of
diligence, presentment, demand of payment, filing of claims with a court in the
event of insolvency or bankruptcy of the Company, any right to require a
proceeding first against the Company, protest, notice and all demands whatsoever
and covenants that its Guarantee will not be discharged except by complete
performance of the obligations contained in the Notes, this Indenture and this
Guarantee.  If any Holder or the Trustee is required by any court or otherwise
to return to the Company or to any Guarantor, or any custodian, trustee,
liquidator or other similar official acting in relation to the Company or such
Guarantor, any amount paid by the Company or such Guarantor to the Trustee or
such Holder, this Guarantee, to the extent theretofor discharged, shall be
reinstated in full force and effect.  Each Guarantor further agrees that, as
between it, on the one hand, and the Holders of Notes and the Trustee, on the
other hand, (a) subject to this Article Thirteen, the maturity of the
obligations guaranteed hereby may be accelerated as provided in Article Five
hereof for the purposes of this Guarantee, notwithstanding any stay, injunction
or other prohibition preventing such acceleration in respect of the obligations
guaranteed hereby, and (b) in the event of any acceleration of such obligations
as provided in Article Five hereof, such obligations (whether or not due and
payable) shall forthwith become due and payable by the Guarantors for the
purpose of this Guarantee.
<PAGE>
 
                                     -73-

          This Guarantee shall remain in full force and effect and continue to
be effective should any petition be filed by or against the Company for
liquidation or reorganization, should the Company become insolvent or make an
assignment for the benefit of creditors or should a receiver or trustee be
appointed for all or any significant part of the Company's assets, and shall, to
the fullest extent permitted by law, continue to be effective or be reinstated,
as the case may be, if at any time payment and performance of the Notes are,
pursuant to applicable law, rescinded or reduced in amount, or must otherwise be
restored or returned by any obligee on the Notes, whether as a "voidable
preference," "fraudulent transfer" or otherwise, all as though such payment or
performance had not been made.  In the event that any payment, or any part
thereof, is rescinded, reduced, restored or returned, the Notes shall, to the
fullest extent permitted by law, be reinstated and deemed reduced only by such
amount paid and not so rescinded, reduced, restored or returned.

          No stockholder, officer, director, employer or incorporator, past,
present or future, or any Guarantor, as such, shall have any personal liability
under this Guarantee by reason of his, her or its status as such stockholder,
officer, director, employer or incorporator.

          The Guarantors shall have the right to seek contribution from any non-
paying Guarantor so long as the exercise of such right does not impair the
rights of the Holders under this Guarantee.

          Notwithstanding any of the foregoing, each Guarantor's liability under
this Section 13.01 shall be limited to the maximum amount that would not result
in such Guarantor's Guarantee under this Section 13.01 constituting a fraudulent
conveyance or fraudulent transfer under applicable law.

          Section 13.02.   Execution and Delivery of Guarantee.
                           ----------------------------------- 

          To further evidence the Guarantee set forth in Section 13.01, each
Guarantor hereby agrees that a notation of such Guarantee, substantially in the
form included in Exhibit E hereto, shall be endorsed on each Note authenticated
and delivered by the Trustee after such Guarantee is executed and executed by
either manual or facsimile signature of an Officer of each Guarantor.  The
validity and enforceability of any Guarantee shall not be affected by the fact
that it is not affixed to any particular Note.

          Each of the Guarantors hereby agrees that its Guarantee set forth in
Section 13.01 shall remain in full force and effect notwithstanding any failure
to endorse on each Note a notation of such Guarantee.

          If an Officer of a Guarantor whose signature is on this Indenture or a
Note no longer holds that office at the time the Trustee authenticates such Note
or at any time thereafter, such Guarantor's Guarantee of such Note shall be
valid nevertheless.

          The delivery of any Note by the Trustee, after the authentication
thereof hereunder, shall constitute due delivery of any Guarantee set forth in
this Indenture on behalf of the Guarantor.

          Section 13.03.   Additional Guarantors.
                           --------------------- 

          Any person who was not a Guarantor at the time this Indenture was
executed may become a Guarantor by executing and delivering to the Trustee (a) a
supplemental indenture in form and substance satisfactory to the Trustee, which
subjects such person to the provisions of this Indenture as a Guarantor, and (b)
an Opinion of Counsel to the effect that such supplemental indenture has been
duly authorized and executed by such person and constitutes the legal, valid,
binding and enforceable obligation of such person (subject to 
<PAGE>
 
                                     -74-

such customary exceptions concerning fraudulent conveyance laws, creditors'
rights and equitable principles as may be acceptable to the Trustee in its
discretion).

                           -----------------------------------------------   
Senior Indebtedness.
- -------------------

          Each Guarantor covenants and agrees, and each Holder of a Note, by its
acceptance thereof, likewise covenants and agrees, that all payments pursuant to
the Guarantee made by or on behalf of such Guarantor are hereby expressly made
subordinate and subject in right of payment as provided in this Article Thirteen
to the prior payment in full in cash of all amounts payable under all existing
and future Guarantor Senior Indebtedness of such Guarantor including such
Guarantor's guarantees of the Company's Obligations under the New Credit
Agreement.

          This Section 13.04 and the following Sections 13.05 through 13.17 of
this Article Thirteen shall constitute a continuing offer to all persons who, in
reliance upon such provisions, become Holders of, or continue to hold Guarantor
Senior Indebtedness of any Guarantor and, to the extent set forth in Section
13.06(b), Holders of Designated Senior Indebtedness; and such provisions are
made for the benefit of the Holders of Guarantor Senior Indebtedness of each
Guarantor and, to the extent set forth in Section 13.06(b), Holders of
Designated Senior Indebtedness; and such Holders (to such extent) are made
obligees hereunder and they or each of them may enforce such provisions.

                           -----------------------------------------------------
Guarantor.
- ---------

          In the event of (a) any insolvency or bankruptcy case or proceeding,
or any receivership, liquidation, reorganization or other similar case or
proceeding in connection therewith, relative to any Guarantor or to its
creditors, as such, or to its assets or (b) any liquidation, dissolution or
other winding-up of any Guarantor, whether voluntary or involuntary and whether
or not involving insolvency or bankruptcy, or (c) any assignment for the benefit
of creditors or any other marshalling of assets or liabilities of any Guarantor,
then and in any such event:

          (1)  the holders of all Guarantor Senior Indebtedness of such
     Guarantor shall be entitled to receive payment in full in cash or, as
     acceptable to the holders of such Guarantor Senior Indebtedness, in any
     other manner of all amounts due on or in respect of all such Guarantor
     Senior Indebtedness (including, in the case of Obligations under the New
     Credit Agreement, and related Currency and Interest Rate Agreement
     Obligations of such Guarantor, any interest accruing subsequent to the
     filing of a petition for bankruptcy at the rate provided for in the
     documentation governing such Obligations under the New Credit Agreement,
     and Interest Rate Agreement Obligations of such Guarantor, as the case may
     be, whether or not such interest is an allowed claim under applicable law),
     or provision shall be made for such payment, before the Holders of the
     Notes are entitled to receive, pursuant to this Guarantee, any payment or
     distribution of any kind or character by or on behalf of such Guarantor on
     account of the Guarantor's Obligations under the Notes; and

          (2)  any payment or distribution of assets of such Guarantor of any
     kind or character, whether in cash, property or securities, by set-off or
     otherwise, to which the Holders or the Trustee would be entitled but for
     the subordination provisions of this Article Thirteen shall be paid by the
     liquidating trustee or agent or other person making such payment or
     distribution, whether a trustee in bankruptcy, a receiver or liquidating
     trustee or otherwise, directly to the Holders of Guarantor Senior
     Indebtedness of such Guarantor or their representative or representatives
     or to the trustee or trustees under any indenture under which any
     instruments evidencing any of such Guarantor Senior Indebted-

     ness may have been issued, ratably according to the aggregate amounts
     remaining unpaid on account of such Guarantor Senior Indebtedness held or
     represented by each, to the extent necessary to make payment in full in
     cash of all such Guarantor Senior Indebtedness remaining unpaid, after
     giving effect to any concurrent payment or distribution to the Holders of
     such Guarantor Senior Indebtedness; and

          (3)  in the event that, notwithstanding the foregoing provisions of
     this Section 13.05, the Trustee or the Holder of any Note shall have
     received any payment or distribution of assets of such Guarantor of any
     kind or character, whether in cash, property or securities, in respect of
     any Obligations of such Guarantor under this Guarantee before all Guarantor
     Senior Indebtedness of such Guarantor is paid in full in cash or payment
     thereof provided for, then and in such event such payment or distribution
     shall be paid over or delivered forthwith to the Senior Representative for
     application to the payment of all such Guarantor Senior Indebtedness
     remaining unpaid, to the extent necessary to pay all of such Guarantor
     Senior Indebtedness in full in cash, after giving effect to any concurrent
     payment or distribution to or for the Holders of such Guarantor Senior
     Indebtedness.  Any such payment or distribution of assets received by the
     Trustee, which is required to be paid over to the Senior Representative,
     will be held in trust by the Trustee for the benefit of the Holders of the
     Guarantor Senior Indebtedness.

                            --------------------------------------------------
Senior Indebtedness in Default.
- ------------------------------

          (a)  Unless Section 13.05 shall be applicable, after the occurrence of
a Payment Default with respect to any Guarantor Senior Indebtedness no payment
or distribution of any assets of such Guarantor of any kind or character shall
be made by or on behalf of such Guarantor on account of the Guarantor's
Obligations pursuant to the Notes or on account of the purchase, redemption,
defeasance or other acquisition of the Obligations pursuant to the Notes or on
account of any other Obligations of such Guarantor under this Guarantee unless
and until such Payment Default shall have been cured or waived or shall have
ceased to exist or the Guarantor Senior Indebtedness as to which such Payment
Default relates shall have been discharged or paid in full in cash, after which,
subject to Section 13.05 (if applicable), such Guarantor shall resume making any
and all required payments in respect of its Obligations under this Guarantee.

          (b)  Unless Section 13.05 shall be applicable, during any Payment
Blockage Period with respect to any Guarantor Senior Indebtedness, no payment or
distribution of any assets of a Guarantor of any kind or character shall be made
by or on behalf of a Guarantor on account of the Guarantor's Obligations on the
Notes or on account of the purchase, redemption, defeasance or other acquisition
of the Guarantor's Obligations on the Notes or on account of any of the other
Obligations of such Guarantor under this Guarantee; provided that the foregoing
prohibition shall not apply unless such Payment Blockage Period has been
instituted under Section 14.03(b) by a Senior Representative acting for Holders
of Designated Senior Indebtedness which also constitutes Guarantor Senior
Indebtedness. Upon the termination of any Payment Blockage Period, subject to
Section 13.05 (if applicable), such Guarantor shall resume making any and all
required payments in respect of its Obligations under this Guarantee.

          (c)  In the event that, notwithstanding the foregoing, the Trustee or
the Holder of any Note shall have received any payment from a Guarantor
prohibited by the foregoing provisions of this Section 13.06, then and in such
event such payment shall be paid over and delivered forthwith to the Senior
Representative initiating the Payment Blockage Period, in trust for distribution
to the Holders of Guarantor Senior

Indebtedness, prompt return to the Guarantor, or as a court of competent
jurisdiction shall direct.

          Section 13.07.    Release of a Guarantor.
                            ---------------------- 

          (a)  So long as no Event of Default shall have occurred and be
continuing upon the sale or disposition (whether by merger, stock purchase,
asset sale or otherwise) of a Guarantor (or all or substantially all of the
assets of any such Guarantor or 50% or more of the Capital Stock of any such
Guarantor) to an entity which is not a Subsidiary of the Company, which
transaction is otherwise in compliance with this Indenture, such Guarantor shall
be deemed released from all its Obligations under its Guarantee of the Notes;
provided, however, that any such termination shall occur only to the extent that
all Obligations of such Guarantor under all its Guarantees of, and under all of
its pledges of assets or other security interests which secure, any Indebtedness
of the Company shall also terminate upon such release, sale or transfer. Upon
the release of any Guarantor from its Guarantee pursuant to the provisions of
this Indenture, each other Guarantor not so released shall remain liable for the
full amount of principal of, and interest on, the Notes as and to the extent
provided in this Indenture.

          (b)  The Trustee shall deliver an appropriate instrument evidencing
the release of a Guarantor upon receipt of a request of the Company accompanied
by an Officers' Certificate certifying as to the compliance with this Section
13.07. Any Guarantor not so released or the entity surviving such Guarantor, as
applicable, will remain or be liable under its Guarantee as provided in this
Article Thirteen.

          The Trustee shall execute any documents reasonably requested by the
Company or a Guarantor in order to evidence the release of such Guarantor from
its obligations under its Guarantee endorsed on the Notes and under this Article
Thirteen.

          Except as set forth in Articles Eight and Ten and this Section 13.07,
nothing contained in this Indenture or in any of the Notes shall prevent any
consolidation or merger of a Guarantor with or into the Company or another
Guarantor or shall prevent any sale or conveyance of the property of a Guarantor
as an entirety or substantially as an entirety to the Company or another
Guarantor.

          Section 13.08.    Waiver of Subrogation.
                            --------------------- 

          Each Guarantor hereby irrevocably waives any claim or other rights
which it may now or hereafter acquire against the Company that arise from the
existence, payment, performance or enforcement of such Guarantor's obligations
under this Guarantee and this Indenture, including, without limitation, any
right of subrogation, reimbursement, exoneration, indemnification, and any right
to participate in any claim or remedy of any Holder of Notes against the
Company, whether or not such claim, remedy or right arises in equity, or under
contract, statute or common law, including, without limitation, the right to
take or receive from the Company, directly or indirectly, in cash or other
property or by set-off or in any other manner, payment or security on account of
such claim or other rights. If any amount shall be paid to any Guarantor in
violation of the preceding sentence and the Notes shall not have been paid in
full, such amount shall have been deemed to have been paid to such Guarantor for
the benefit of, and held in trust for the benefit of, the Holders of the Notes,
and shall, subject to the subordination provisions of this Article Thirteen and
to Article Fourteen, forthwith be paid to the Trustee for the benefit of such
Holders to be credited and applied upon the Notes, whether matured or unmatured,
in accordance with the terms of this Indenture. Each Guarantor acknowledges that
it will receive direct and indirect benefits from the financing arrangements
contemplated by this Indenture and that the waiver set forth in this Section
13.08 is knowingly made in contemplation of such benefits.

          Section 13.09.    Guarantee Subordination Provisions Solely To Define
                            ---------------------------------------------------
Relative Rights.
- --------------- 

          The subordination provisions of this Article are and are intended
solely for the purpose of defining the relative rights of the Holders of the
Notes on the one hand and the Holders of Guarantor Senior Indebtedness of each
Guarantor and, to the extent set forth in Section 13.06, Holders of Designated
Senior Indebtedness on the other hand. Nothing contained in this Article
Thirteen (other than a release pursuant to Section 13.07) or elsewhere in this
Indenture or in the Notes is intended to or shall (a) impair, as among each
Guarantor, its creditors other than Holders of its Guarantor Senior Indebtedness
and the Holders of the Notes, the obligation of such Guarantor, which is
absolute and unconditional, to make payments to the Holders in respect of its
obligations under this Guarantee as and when the same shall become due and
payable in accordance with their terms; or (b) affect the relative rights
against such Guarantor of the Holders of the Notes and creditors of such
Guarantor other than the Holders of the Guarantor Senior Indebtedness of such
Guarantor; or (c) prevent the Trustee or the Holder of any Note from exercising
all remedies otherwise permitted by applicable law upon Default or an Event of
Default under this Indenture, subject to the rights, if any, under the
subordination provisions of this Article Thirteen of the Holders of Guarantor
Senior Indebtedness of the Guarantors hereunder and, to the extent set forth in
Section 13.06, Holders of Designated Senior Indebtedness (1) in any case,
proceeding, dissolution, liquidation or other winding-up, assignment for the
benefit of creditors or other marshaling of assets and liabilities of the
Guarantor referred to in Section 13.05, to receive, pursuant to and in
accordance with such Section, cash, property and securities otherwise payable or
deliverable to the Trustee or such Holder, or (2) under the conditions specified
in Section 13.06, to prevent any payment prohibited by such Section or enforce
their rights pursuant to Section 13.06(c).

          The failure by any Guarantor to make a payment in respect of its
obligations under this Guarantee by reason of any provision of this Article
Thirteen shall not be construed as preventing the occurrence of a Default or an
Event of Default hereunder.

          Section 13.10.    Trustee To Effectuate Subordination of Guarantee
                            ------------------------------------------------
Obligations.
- ----------- 

          Each Holder of a Note by his acceptance thereof authorizes and directs
the Trustee on his behalf to take such action as may be necessary or appropriate
to effectuate the subordination provided in this Article Thirteen and appoints
the Trustee his attorney-in-fact for any and all such purposes, including, in
the event of any dissolution, winding-up, liquidation or reorganization of any
Guarantor whether in bankruptcy, insolvency, receivership proceedings, or
otherwise, the timely filing of a claim for the unpaid balance of the
indebtedness of such Guarantor owing to such Holder in the form required in such
proceedings and the causing of such claim to be approved. If the Trustee does
not file such a claim prior to 30 days before the expiration of the time to file
such a claim, the Holders of Guarantor Senior Indebtedness, or any
representative, may file such a claim on behalf of Holders of the Notes.

          Section 13.11.    No Waiver of Guarantee Subordination Provisions.
                            ----------------------------------------------- 

          (a)  No right of any present or future Holder of any Guarantor Senior
Indebtedness of any Guarantor or Designated Senior Indebtedness to enforce
subordination as herein provided shall at any time in any way be prejudiced or
impaired by any act or failure to act on the part of the Company or any
Guarantor or by any act or failure to act, in good faith, by any such Holder, or
by any non-compliance by the Company or any Guarantor with the terms, provisions
and covenants of this Indenture, regardless of any knowledge thereof any such
Holder may have or be otherwise charged with.
<PAGE>
 
                                     -78-

          (b)  Without limiting the generality of subsection (a) of this Section
13.11, the Holders of Guarantor Senior Indebtedness of any Guarantor may, at any
time and from time to time, without the consent of or notice to the Trustee or
the Holders of the Notes, without incurring responsibility to the Holders of the
Notes and without impairing or releasing the subordination provided in this
Article Thirteen or the obligations hereunder of the Holders of the Notes to the
Holders of such Guarantor Senior Indebtedness, do any one or more of the
following:  (1) change the manner, place or terms of payment or extend the time
of payment of, or renew or alter, such Guarantor Senior Indebtedness or any
Senior Indebtedness as to which such Guarantor Senior Indebtedness relates or
any instrument evidencing the same or any agreement under which such Guarantor
Senior Indebtedness or such Senior Indebtedness is outstanding; (2) sell,
exchange, release or otherwise deal with any property pledged, mortgaged or
otherwise securing such Guarantor Senior Indebtedness or any Senior Indebtedness
as to which such Guarantor Senior Indebtedness relates; (3) release any person
liable in any manner for the collection or payment of such Guarantor Senior
Indebtedness or any Senior Indebtedness as to which such Guarantor Senior
Indebtedness relates; and (4) exercise or refrain from exercising any rights
against such Guarantor and any other person; provided that in no event shall any
such actions limit the right of the Holders of the Notes to take any action to
accelerate the maturity of the Notes pursuant to Article Five hereof or to
pursue any rights or remedies hereunder or under applicable laws if the taking
of such action does not otherwise violate the terms of this Indenture.

          Section 13.12.    Guarantors To Give Notice to Trustee.
                            ------------------------------------ 

          (a)  The Company and each Guarantor shall give prompt written notice
to the Trustee of any fact known to such Guarantor which would prohibit the
making of any payment to or by the Trustee in respect of the Notes.
Notwithstanding the subordination provisions of this Article or any other
provision of this Indenture, the Trustee shall not be charged with knowledge of
the existence of any facts which would prohibit the making of any payment to or
by the Trustee in respect of the Notes, unless and until the Trustee shall have
received written notice thereof at its Corporate Trust Office from the Company,
such Guarantor or a Holder of its Guarantor Senior Indebtedness or from any
trustee, fiduciary or agent therefor; and, prior to the receipt of any such
written notice, the Trustee, subject to the provisions of this Section 13.12,
shall be entitled in all respects to assume that no such facts exist; provided
that if the Trustee shall not have received the notice provided for in this
Section 13.12 at least two Business Days prior to the date upon which by the
terms hereof any money may become payable for any purpose under this Indenture
(including, without limitation, the payment of the principal of or interest on
any Note), then, anything herein contained to the contrary notwithstanding but
without limiting the rights and remedies of the Holders of such Guarantor Senior
Indebtedness or any trustee, fiduciary or agent thereof, the Trustee shall have
full power and authority to receive such money and to apply the same to the
purpose for which such money was received and shall not be affected by any
notice to the contrary which may be received by it within two Business Days
prior to such date; nor shall the Trustee be charged with knowledge of the
curing of any such default or the elimination of the act or condition preventing
any such payment unless and until the Trustee shall have received an Officers'
Certificate from such Guarantor to such effect.

          (b)  Subject to the provisions of Section 6.01, the Trustee shall be
entitled to rely on the delivery to it of a written notice to the Trustee, by a
person representing himself to be a Holder of Guarantor Senior Indebtedness of
any Guarantor (or a trustee, fiduciary or agent therefor).  In the event that
the Trustee determines in good faith that further evidence is required with
respect to the right of any person as a Holder of Guarantor Senior Indebtedness
of any Guarantor to participate in any payment or distribution pursuant to this
Article Thirteen, the Trustee may request such person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Guarantor Senior
Indebtedness of each Guarantor held by such person, the extent to which such
person is entitled to participate in such payment or distribution and any other
facts pertinent to 
<PAGE>
 
                                     -79-


the rights of such person under this Article Thirteen, and if such evidence is
not furnished, the Trustee may defer any payment to such person pending judicial
determination as to the right of such person to receive such payment.

- ------------------------------------------------------------

          Upon any payment or distribution of assets of any Guarantor referred
to in this Article Thirteen, the Trustee, subject to the provisions of Section
6.01, and the Holders shall be entitled to rely upon any order or decree entered
by any court of competent jurisdiction in which such insolvency, bankruptcy,
receivership, liquidation, reorganization, dissolution, winding-up or similar
case or proceeding is pending, or a certificate of the trustee in bankruptcy,
receiver, liquidating trustee, custodian, assignee for the benefit of creditors,
agent or other person making such payment or distribution, delivered to the
Trustee or to the Holders, for the purpose of ascertaining the persons entitled
to participate in such payment or distribution, the Holders of Guarantor Senior
Indebtedness of such Guarantor and other Indebtedness of such Guarantor, the
amount thereof or payable thereon, the amount or amounts paid or distributed
thereon and all other facts pertinent thereto or to this Article Thirteen;
provided that the foregoing shall apply only if such court has been fully
apprised of the provisions of this Article Thirteen.

                            -------------------------------------------------
Indebtedness; Preservation of Trustee's Rights.
- ---------------------------------------------- 

          The Trustee in its individual capacity shall be entitled to all the
rights set forth in this Article Thirteen with respect to any Guarantor Senior
Indebtedness of any Guarantor which may at any time be held by the Trustee, to
the same extent as any other Holder of such Guarantor Senior Indebtedness, and
nothing in this Indenture shall deprive the Trustee of any of its rights as such
Holder. Nothing in this Article Thirteen shall apply to claims of, or payments
to, the Trustee under or pursuant to Section 6.07.

          Section 13.15.    Article Thirteen Applicable to Paying Agents.
                            -------------------------------------------- 

          In case at any time any Paying Agent other than the Trustee shall have
been appointed by the Company and be then acting hereunder, the term "Trustee"
as used in this Article Thirteen shall in such case (unless the context
otherwise requires) be construed as extending to and including such Paying Agent
within its meaning as fully for all intents and purposes as if such Paying Agent
were named in this Article Thirteen in addition to or in place of the Trustee;
provided that Section 13.14 shall not apply to the Company or any Affiliate of
the Company if it or such Affiliate acts as Paying Agent.

          Section 13.16.    No Suspension of Remedies Subject to Rights of
                            ----------------------------------------------
Holders of Guarantor Senior Indebtedness.
- ----------------------------------------

          Nothing contained in this Article Thirteen shall limit the right of
the Trustee or the Holders of Notes to take any action to accelerate the
maturity of the Notes pursuant to Article Five or to pursue any rights or
remedies hereunder or under applicable law, subject to the rights, if any, under
this Article Thirteen of the Holders, from time to time, of Guarantor Senior
Indebtedness of the Guarantors.

                            --------------------------------------------------- 

          With respect to the Holders of Guarantor Senior Indebtedness of any
Guarantor, the Trustee undertakes to perform or to observe only such of its
covenants and obligations as are specifically set forth in this Article Thirteen
(and in Article Fourteen with respect to Senior Indebtedness), and no implied
covenants or obligations with respect to the Holders of Guarantor Senior
Indebtedness of any Guarantor shall be read into this Indenture against the
Trustee.  The Trustee shall not be deemed to owe any fiduciary duty to the
Holders of Guarantor Senior Indebtedness of any Guarantor and the Trustee shall
not be liable to any Holder of Guarantor Senior Indebtedness of any Guarantor if
it shall mistakenly pay over or deliver to Holders, the Company or any other
person moneys or assets to which any Holder of Guarantor Senior Indebtedness of
any Guarantor shall be entitled by virtue of this Article Thirteen or otherwise.

          Section 13.18.    Subrogation.
                            ----------- 

          Upon the payment in full in cash of all amounts payable under or in
respect of Guarantor Senior Indebtedness of the Guarantors and of all Senior
Indebtedness of the Company, the Holders shall be subrogated to the rights of
the Holders of such Guarantor Senior Indebtedness of the Guarantors to receive
payments or distributions of assets of any Guarantor made on such Guarantor
Senior Indebtedness of the Guarantors until all amounts due under the Guarantee
shall be paid in full; and for the purposes of such subrogation, no payments or
distributions to Holders of such Guarantor Senior Indebtedness of the Guarantors
of any cash, property or securities to which Holders of the Notes would be
entitled except for the provisions of this Article Thirteen, and no payment
pursuant to the provisions of this Article Thirteen to Holders of such Guarantor
Senior Indebtedness of the Guarantors by the Holders, shall, as between each
Guarantor, its creditors other than Holders of such Guarantor Senior
Indebtedness of the Guarantors and the Holders, be deemed to be a payment by
such Guarantor to or on account of such Guarantor Senior Indebtedness of the
Guarantors, its being understood that the provisions of this Article Thirteen
are solely for the purpose of defining the relative rights of the Holders of
such Guarantor Senior Indebtedness of the Guarantors, on the one hand, and the
Holders, on the other hand.

          If any payment or distribution to which the Holders would otherwise
have been entitled but for the provisions of this Article Thirteen shall have
been applied, pursuant to the provisions of this Article Thirteen, to the
payment of all amounts payable under the Guarantor Senior Indebtedness of the
Guarantors, then and in such case, the Holders shall be entitled to receive from
the Holders of such Guarantor Senior Indebtedness of the Guarantors at the time
outstanding any payments or distributions received by such Holders of Guarantor
Senior Indebtedness of the Guarantors in excess of the amount sufficient to pay
all amounts payable under or in respect of such Guarantor Senior Indebtedness of
the Guarantors in full.

          Section 14.01.    Notes Subordinate to Senior Indebtedness.
                            ---------------------------------------- 

          The Company covenants and agrees, and each Holder of a Note, by his
acceptance thereof, likewise covenants and agrees, that, to the extent and in
the manner hereinafter set forth in this Article Fourteen, the Indebtedness
represented by the Notes are hereby expressly made subordinate and subject in
right of 
<PAGE>
 
                                     -81-

payment as provided in this Article to the prior payment in full in cash or Cash
Equivalents of all Senior Indebtedness (including the indebtedness under the New
Credit Agreement).

          This Article Fourteen shall constitute a continuing offer to all
persons who, in reliance upon such provisions, become Holders of, or continue to
hold Senior Indebtedness; and such provisions are made for the benefit of the
Holders of Senior Indebtedness; and such holders are made obligees hereunder and
they or each of them individually or through their representative may enforce
such provisions.

          Section 14.02.   Payment Over of Proceeds upon Dissolution, etc.
                           ---------------------------------------------- 

          In the event of (a) any insolvency or bankruptcy case or proceeding,
or any receivership, liquidation, reorganization or other similar case or
proceeding in connection therewith, relating to the Company, or (b) any
liquidation, dissolution or other winding-up of the Company, whether voluntary
or involuntary and whether or not involving insolvency or bankruptcy, then and
in any such event:

          (1)  the holders of all Senior Indebtedness shall be entitled to
     receive payment in full in cash or Cash Equivalents of all Obligations due
     in respect of such Senior Indebtedness before the Holders are entitled to
     receive any payment or distribution of any kind or character on account of
     the Notes; and

          (2)  any payment or distribution of assets of the Company of any kind
     or character, whether in cash, property or securities, by set-off or
     otherwise, to which the Holders or the Trustee would be entitled but for
     the provisions of this Article shall be paid by the liquidating trustee or
     agent or other person making such payment or distribution, whether a
     trustee in bankruptcy, a receiver or liquidating trustee or otherwise,
     directly to the Holders of Senior Indebtedness or their representative or
     representatives or to the trustee or trustees under any indenture under
     which any instruments evidencing any of such Senior Indebtedness may have
     been issued, ratably according to the aggregate amounts remaining unpaid on
     account of the Senior Indebtedness held or represented by each, to the
     extent necessary to make payment in full in cash or Cash Equivalents of all
     Senior Indebtedness remaining unpaid, after giving effect to any concurrent
     payment or distribution to the Holders of such Senior Indebtedness; and

          (3)  in the event that, notwithstanding the foregoing provisions of
     this Section 14.02, the Trustee or the Holder of any Note shall have
     received any payment or distribution of properties or assets of the Company
     of any kind or character, whether in cash, property or securities, by set
     off or otherwise in respect of the Notes before all Senior Indebtedness is
     paid or provided for in full in cash, then and in such event such payment
     or distribution shall be paid over or delivered forthwith to the trustee in
     bankruptcy, receiver, liquidating trustee, custodian, assignee, agent or
     other person making payment or distribution of assets of the Company for
     application to the payment of all Senior Indebtedness remaining unpaid, to

          Section 14.03.   Suspension of Payment When Designated Senior
                           --------------------------------------------
Indebtedness is in Default.
- -------------------------- 

          (a)  Unless Section 14.02 shall be applicable, during the continuance
of any default in the payment of any Designated Senior Indebtedness pursuant to
which the maturity thereof may immediately be accelerated  beyond any applicable
grace period and after receipt by the Trustee from representatives of holders of
such Designated Senior Indebtedness of written notice of such default, no
payment or distribution of any assets of the Company of any kind or character
(excluding any payment or distribution of certain permitted equity or
subordinated securities) shall be made on account of the principal of, premium,
if any, or interest on, or the purchase, redemption or other acquisition of, the
Notes unless and until such default has been cured or waived or has ceased to
exist or such Designated Senior Indebtedness shall have been discharged or paid
in full.

          (b)  Unless Section 14.02 shall be applicable, upon (1) the occurrence
of a Non-payment Default and (2) receipt by the Trustee from the representatives
of any Holders of Designated Senior Indebtedness of written notice of such
occurrence (a "Payment Blockage Notice") stating that a Non-Payment Default has
occurred and is continuing pursuant to Section 14.03(b) of this Indenture, no
payment or distribution of any assets of the Company of any kind or character
(excluding any payment or distribution of certain permitted equity or
subordinated securities) shall be made by or on behalf of the Company on account
of the principal of, premium, if any, or interest on, or the purchase,
redemption or other acquisition of, the Notes for a period ("Payment Blockage
Period") commencing on the date of receipt by the Trustee of such notice and
will end on the earlier to occur of the following events (subject to any
blockage of payments that may then be in effect under Section 14.02 or
subsection (a) of this Section 14.03), (i) 179 days shall have elapsed since the
receipt of such notice of a Non-payment Default (provided that such Designated
Senior Indebtedness shall not theretofor have been accelerated), (ii) such
default is cured or waived or ceases to exist or such Designated Senior
Indebtedness is discharged or (iii) such Payment Blockage Period shall have been
terminated by written notice to the Company or the Trustee from the
representatives of holders of Designated Senior Indebtedness initiating such
Payment Blockage Period. After the end of any Payment Blockage Period the
Company shall promptly resume making any and all required payments in respect of
the Notes, including any missed payments. Notwithstanding anything in the
subordination provisions of this Indenture or the Notes to the contrary, (x) in
no event shall a Payment Blockage Period extend beyond 179 days from the date of
the receipt by the Trustee of the notice initiating such Payment Blockage
Period, (y) there shall be a period of at least 186 consecutive days in each
365-day period when no Payment Blockage Period is in effect and (z) not more
than one Payment Blockage Period with respect to the Notes may be commenced
within any period of 365 consecutive days.  A Non-payment Default with respect
to Designated Senior Indebtedness that existed or was continuing on the date of
the commencement of any Payment Blockage Period with respect to the Designated
Senior Indebtedness initiating such Payment Blockage Period cannot be made the
basis for the commencement of a second Payment Blockage Period, whether or not
within a period of 365 consecutive days, unless such default has been cured or
waived for a period of not less than 90 consecutive days and subsequently
recurs.

          (c)  In the event that, notwithstanding the foregoing, the Trustee or
the Holder of any Note shall have received any payment or distribution
prohibited by the foregoing provisions of this Section 14.03, then and in such
event such payment or distribution shall be paid over and delivered forthwith to
representa-
<PAGE>
 
                                     -83-

tives of the Holders or as a court of competent jurisdiction shall direct for
application to the payment of any due and unpaid Senior Indebtedness, to the
extent necessary to pay all such due and unpaid Senior Indebtedness in cash,
after giving effect to any concurrent payment to or for the Holders of Senior
Indebtedness.

          Section 14.04.   Trustee's Relation to Senior Indebtedness.
                           ----------------------------------------- 

          With respect to the Holders of Senior Indebtedness, the Trustee
undertakes to perform or to observe only such of its covenants and obligations
as are specifically set forth in this Article Fourteen (and in Article Thirteen
with respect to any Guarantor Senior Indebtedness of the respective Guarantors),
and no implied covenants or obligations with respect to the Holders of Senior
Indebtedness shall be read into this Indenture against the Trustee.  The Trustee
shall not be deemed to owe any fiduciary duty to the Holders of Senior
Indebtedness and the Trustee shall not be liable to any Holder of Senior
Indebtedness if it shall mistakenly pay over or deliver to Holders, the Company,
the Guarantors or any other person moneys or assets to which any Holder of
Senior Indebtedness shall be entitled by virtue of this Article Fourteen or
otherwise.

          Section 14.05.   Subrogation to Rights of Holders of Senior
                           ------------------------------------------
Indebtedness.
- ------------

          Upon the payment in full in cash of all Senior Indebtedness, the
Holders shall be subrogated to the rights of the holders of such Senior
Indebtedness to receive payments and distributions of cash, property and
securities applicable to the Senior Indebtedness until the principal of and
interest on the Notes shall be paid in full in cash or cash equivalents.  For
purposes of such subrogation, no payments or distributions to the holders of
Senior Indebtedness of any cash, property or securities to which the Holders or
the Trustee would be entitled except for the provisions of this Article, and no
payments over pursuant to the provisions of this Article to the holders of
Senior Indebtedness by Holders or the Trustee shall, as among the Company, its
creditors other than holders of Senior Indebtedness, and the Holders, be deemed
to be a payment or distribution by the Company to or on account of the Senior
Indebtedness.

          If any payment or distribution to which the Holders would otherwise
have been entitled but for the provisions of this Article Fourteen shall have
been applied, pursuant to the provisions of this Article Fourteen, to the
payment of all amounts payable under the Senior Indebtedness of the Company,
then and in such case the Holders shall be entitled to receive from the holders
of such Senior Indebtedness at the time outstanding any payments or
distributions received by such holders of such Senior Indebtedness in excess of
the amount sufficient to pay all amounts payable under or in respect of such
Senior Indebtedness in full in cash or cash equivalents.

          Section 14.06.   Provisions Solely To Define Relative Rights.
                           ------------------------------------------- 

          The provisions of this Article Fourteen are and are intended solely
for the purpose of defining the relative rights of the Holders on the one hand
and the holders of Senior Indebtedness on the other hand.  Nothing contained in
this Article Fourteen or elsewhere in this Indenture or in the Notes is intended
to or shall (a) impair, as among the Company, its creditors other than holders
of Senior Indebtedness and the Holders, the obligation of the Company, which is
absolute and unconditional, to pay to the Holders the principal of, premium, if
any, and interest on the Notes as and when the same shall become due and payable
in accordance with their terms; or (b) affect the relative rights against the
Company of the Holders and creditors of the Company other than the holders of
Senior Indebtedness; or (c) prevent the Trustee or the Holder of any Note from
exercising all remedies otherwise permitted by applicable law upon a Default or
an Event of Default under this Indenture, subject to the rights, if any, under
this Article Fourteen of the holders of Senior Indebtedness (1) in any case,
proceeding, dissolution, liquidation or other winding up, assignment for the
benefit of creditors or 
<PAGE>
 
                                     -84-

other marshalling of assets and liabilities of the Company referred to in
Section 14.02, to receive, pursuant to and in accordance with such Section,
cash, property and securities otherwise payable or deliverable to the Trustee or
such Holder, or (2) under the conditions specified in Section 14.03, to prevent
any payment prohibited by such Section or enforce their rights pursuant to
Section 14.03(c).

          The failure to make a payment on the Notes by reason of any provision
of this Article Fourteen shall not be construed as preventing the occurrence of
a Default or an Event of Default hereunder.

          Section 14.07.   Trustee To Effectuate Subordination.
                           ----------------------------------- 

          Each Holder of a Note by his acceptance thereof authorizes and directs
the Trustee on his behalf to take such action as may be necessary or appropriate
to effectuate the subordination provided in this Article Fourteen and appoints
the Trustee his attorney-in-fact for any and all such purposes, including, in
the event of any dissolution, winding-up, liquidation or reorganization of the
Company whether in bankruptcy, insolvency, receivership proceedings, or
otherwise, the timely filing of a claim for the unpaid balance of the
Indebtedness of the Company owing to such Holder in the form required in such
proceedings and the causing of such claim to be approved.  If the Trustee does
not file such a claim prior to 30 days before the expiration of the time to file
such a claim, the holders of Senior Indebtedness, or any Senior Representative,
may file such a claim on behalf of Holders of the Notes.

          Section 14.08.   No Waiver of Subordination Provisions.
                           ------------------------------------- 

          (a)  No right of any present or future holder of any Senior
Indebtedness to enforce subordination as herein provided shall at any time in
any way be prejudiced or impaired by any act or failure to act on the part of
the Company or by any act or failure to act, in good faith, by any such Holder,
or by any non-compliance by the Company with the terms, provisions and covenants
of this Indenture, regardless of any knowledge thereof any such Holder may have
or be otherwise charged with.

          (b)  Without limiting the generality of subsection (a) of this Section
14.08, the Holders of Senior Indebtedness may, at any time and from time to
time, without the consent of or notice to the Trustee or the Holders, without
incurring responsibility to the Holders and without impairing or releasing the
subordination provided in this Article Fourteen or the obligations hereunder of
the Holders to the holders of Senior Indebtedness, do any one or more of the
following:  (1) change the manner, place or terms of payment or extend the time
of payment of, or renew or alter, Senior Indebtedness or any instrument
evidencing the same or any agreement under which Senior Indebtedness is
outstanding; (2) sell, exchange, release or otherwise deal with any property
pledged, mortgaged or otherwise securing Senior Indebtedness; (3) release any
person liable in any manner for the collection or payment of Senior
Indebtedness; and (4) exercise or refrain from exercising any rights against the
Company and any other person; provided, however, that in no event shall any such
actions limit the right of the Holders to take any action to accelerate the
maturity of the Notes pursuant to Article Five hereof or to pursue any rights or
remedies hereunder or under applicable laws if the taking of such action does
not otherwise violate the terms of this Indenture.

          Section 14.09.   Notice to Trustee.
                           ----------------- 

          (a)  The Company shall give prompt written notice to the Trustee of
any fact known to the Company which would prohibit the making of any payment to
or by the Trustee in respect of the Notes. Notwithstanding the provisions of
this Article Fourteen or any other provision of this Indenture, the Trustee
shall not be charged with knowledge of the existence of any facts which would
prohibit the making of any payment
<PAGE>
 
                                     -85-

to or by the Trustee in respect of the Notes, unless and until the Trustee shall
have received written notice thereof from the Company or a holder of Senior
Indebtedness or from any trustee, fiduciary or agent therefor; and, prior to the
receipt of any such written notice, the Trustee, subject to the provisions of
this Section 14.09, shall be entitled in all respects to assume that no such
facts exist; provided, however, that if the Trustee shall not have received the
notice provided for in this Section 14.09 at least two Business Days prior to
the date upon which by the terms hereof any money may become payable for any
purpose under this Indenture (including, without limitation, the payment of the
principal of or interest on any Note), then, anything herein contained to the
contrary notwithstanding but without limiting the rights and remedies of the
holders of Senior Indebtedness or any trustee, fiduciary or agent thereof, the
Trustee shall have full power and authority to receive such money and to apply
the same to the purpose for which such money was received and shall not be
affected by any notice to the contrary which may be received by it within two
Business Days prior to such date; nor shall the Trustee be charged with
knowledge of the curing of any such default or the elimination of the act or
condition preventing any such payment unless and until the Trustee shall have
received an Officers' Certificate to such effect.

          (b)  Subject to the provisions of Section 6.01, the Trustee shall be
entitled to rely on the delivery to it of a written notice to the Trustee by a
person representing himself to be a holder of Senior Indebtedness (or a trustee,
fiduciary or agent therefor) to establish that such notice has been given by a
holder of Senior Indebtedness (or a trustee, fiduciary or agent therefor).  In
the event that the Trustee determines in good faith that further evidence is
required with respect to the right of any person as a holder of Senior
Indebtedness to participate in any payment or distribution pursuant to this
Article Fourteen, the Trustee may request such person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness
held by such person, the extent to which such person is entitled to participate
in such payment or distribution and any other facts pertinent to the rights of
such person under this Article Fourteen, and if such evidence is not furnished,
the Trustee may defer any payment to such person pending judicial determination
as to the right of such person to receive such payment.

          Section 14.10.   Reliance on Judicial Order or Certificate of
                           --------------------------------------------
Liquidating Agent.
- ----------------- 

          Upon any payment or distribution of assets of the Company referred to
in this Article Fourteen, the Trustee, subject to the provisions of Section
6.01, and the Holders, shall be entitled to rely upon any order or decree
entered by any court of competent jurisdiction in which such insolvency,
bankruptcy, receivership, liquidation, reorganization, dissolution, winding-up
or similar case or proceeding is pending, or a certificate of the trustee in
bankruptcy, receiver, liquidating trustee, custodian, assignee for the benefit
of creditors, agent or other person making such payment or distribution,
delivered to the Trustee or to the Holders, for the purpose of ascertaining the
persons entitled to participate in such payment or distribution, the Holders of
Senior Indebtedness and other Indebtedness of the Company, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article; provided, however, that the
foregoing shall apply only if such court has been fully apprised of the
provisions of this Article Fourteen.

          Section 14.11.   Rights of Trustee as a Holder of Senior Indebtedness;
                           -----------------------------------------------------
Preservation of Trustee's Rights.
- -------------------------------- 

          The Trustee in its individual capacity shall be entitled to all the
rights set forth in this Article Fourteen with respect to any Senior
Indebtedness which may at any time be held by it, to the same extent as any
other holder of Senior Indebtedness, and nothing in this Indenture shall deprive
the Trustee of any of its 
<PAGE>
 
                                     -86-

rights as such holder. Nothing in this Article Fourteen shall apply to claims
of, or payments to, the Trustee under or pursuant to Section 6.07.

          Section 14.12.   Article Applicable to Paying Agents.
                           ----------------------------------- 

          In case at any time any Paying Agent other than the Trustee shall have
been appointed by the Company and be then acting hereunder, the term "Trustee"
as used in this Article shall in such case (unless the context otherwise
requires) be construed as extending to and including such Paying Agent within
its meaning as fully for all intents and purposes as if such Paying Agent were
named in this Article Fourteen in addition to or in place of the Trustee;
provided that Section 14.11 shall not apply to the Company or any Affiliate of
the Company if it or such Affiliate acts as Paying Agent.

          Section 14.13.   No Suspension of Remedies.
                           ------------------------- 
 
          Nothing contained in this Article Fourteen shall limit the right of
the Trustee or the Holders to take any action to accelerate the maturity of the
Notes pursuant to Article Five or to pursue any rights or remedies hereunder or
under applicable law, subject to the rights, if any, under this Article Fourteen
of the Holders, from time to time, of Senior Indebtedness.

          THE GSI GROUP, INC., a Delaware corporation (the "Company," which term
includes any successor under the Indenture hereinafter referred to), for value
received, promises to pay _______ to or registered assigns, the principal sum 
of ______ United States Dollars on November 1, 2007, at the office or agency of
the Company referred to below, and to pay interest thereon on May 1 and November
1, in each year, commencing on May 1, 1998 (each an "Interest Payment Date"),
accruing from the Issue Date or from the most recent Interest Payment Date to
which interest has been paid or duly provided for, at the rate of 10 1/4% per
annum, until the principal hereof is paid or duly provided for. Interest shall
be computed on the basis of a 360-day year of twelve 30-day months.

          The interest so payable, and punctually paid or duly provided for, on
any Interest Payment Date will, as provided in the Indenture referred to on the
reverse hereof, be paid in arrears to the Person in whose name this Note (or one
or more predecessor Notes) is registered at the close of business on the April

as the case may be, next preceding such Interest Payment Date.  Any such
interest not so punctually paid, or duly provided for, and interest on such
defaulted interest at the then applicable interest rate borne by the Notes, to

Special Record Date for the payment of such defaulted interest to be fixed by
the Trustee, notice of which shall be given to Holders of Notes not less than 10
days prior to such Special Record Date, or may be paid at any time in any other
lawful manner not inconsistent with the requirements of any securities exchange
on which the Notes may be listed, and upon such notice as may be required by
such exchange, all as more fully provided in such Indenture.

may be made at the option of the Company by check (which may be a check of the
Company) mailed to the address of the Person entitled thereto as such address
shall appear on the Note Register.

          Reference is hereby made to the further provisions of this Note set
forth on the reverse hereof.

          Unless the certificate of authentication hereon has been duly executed

shall not be entitled to any benefit under the Indenture, or be valid or

                   10 1/4% Senior Subordinated Note due 2007

          1.   Indenture.  This Note is one of a duly authorized issue of Notes
               ---------                                                       
of the Company designated as its 10 1/4% Senior Subordinated Notes due 2007,
(the "Notes"), limited (except as otherwise provided in the Indenture referred
to below) in aggregate principal amount to $               , which may be issued
under an indenture (the "Indenture") dated as of November 1, 1997, by and among
the Company, as Issuer and LaSalle National Bank, as trustee (the "Trustee,"
which term includes any successor Trustee under the Indenture), to which
Indenture and all indentures supplemental thereto reference is hereby made for a
statement of the respective rights, limitations of rights, duties, obligations
and immunities thereunder of the Company, the Trustee and the Holders, and of
the terms upon which the Notes are, and are to be, authenticated and delivered.

          All capitalized terms used in this Note which are defined in the
Indenture and not otherwise defined herein shall have the meanings assigned to
them in the Indenture.

          No reference herein to the Indenture and no provisions of this Note or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of, premium, if any, and
interest on this Note at the times, place and rate, and in the coin or currency,
herein prescribed.

          2.   Guarantees.  This Note is entitled to certain senior subordinated
               ----------                                                       
Guarantees, if any, made for the benefit of the Holders.  Reference is hereby
made to Article Thirteen of the Indenture for terms relating to the Guarantees.

          3.   Subordination.  The Indebtedness evidenced by the Notes is, to
               -------------                                                 
the extent and in the manner provided in the Indenture, subordinate and subject
in right of payment to the prior payment in full in cash of all existing and
future Senior Indebtedness (including the Indebtedness under the New Credit
Agreement).  Each Holder, by accepting the same, (a) agrees to and shall be
bound by such provisions, (b) authorizes and directs the Trustee, on behalf of
such Holder, to take such action as may be necessary or appropriate to
effectuate the subordination as provided in the Indenture and (c) appoints the
Trustee attorney-in-fact of such Holder for such purpose; provided, however,
that the Indebtedness evidenced by this Note shall cease to be so subordinate
and subject in right of payment upon any defeasance of this Note referred to in
Paragraph 7 below.

          4.   Redemption.
               ---------- 

          (a)  Optional Redemption.  Subject to earlier redemption in the manner
               -------------------                                              
described in the next two succeeding paragraphs, the Notes will be redeemable at
the option of the Company, in whole or in part, at any time on or after November

set forth below, plus accrued and unpaid interest, if any, to the date of

          <S>                    <C>
          2002                     105.188%
          2003                     103.458

          On or prior to November 1, 2000, the Company may, at its option, use
the net proceeds of an Equity Offering to redeem up to 35% of the originally
issued aggregate principal amount of the Notes, at a redemption price in cash
equal to 110 1/4% of the principal amount thereof, plus accrued and unpaid
interest thereon, if any, to the date of redemption; provided, however, that not
less than $65.0 million in aggregate principal amount of Notes is outstanding
following such redemption. Notice of any such redemption must be given not later
than 60 days after the consummation of the Equity Offering.

          As used in the preceding paragraph, an ''Equity Offering'' means any
public or private sale of equity securities (other than Redeemable Capital
Stock) of the Company; provided, however, that the proceeds (net of any
underwriting discounts or commissions) to the Company from any such private sale
of equity securities shall be at least $20.0 million.

          (b)  Redemption Upon Change of Control.  Following the occurrence of a
               ---------------------------------                                
Change of Control (the date of such occurrence being the ''Change of Control
Date''), the Company will be obligated, not more than 40 or less than 20
business days after the Change of Control Date, to make an offer to purchase (a
''Change of Control Offer'') all of the then outstanding Notes at a purchase
price (the ''Change of Control Purchase Price'') in cash equal to 101% of the
principal amount thereof, plus accrued and unpaid interest thereon, if any, to
the purchase date. The Company will be required to purchase all Notes properly
tendered into the Change of Control Offer and not withdrawn.

          In order to effect such Change of Control Offer, the Company will, not
later than the 40th business day after the Change of Control Date, be obligated
to mail to each holder of Notes notice of the Change of Control Offer, which
notice will govern the terms of the Change of Control Offer and will state,
among other things, the procedures that holders must follow to accept the Change
of Control Offer. The Change of Control Offer will be required to be kept open
for a period of at least 20 business days.

          (c)  Sinking Fund.  The Company will not be required to make any
               ------------                                               
mandatory sinking fund payments in respect of the Notes.

          (d)  Interest Payments.  In the case of any redemption of the Notes,
               -----------------                                              
interest installments whose Stated Maturity is on or prior to the Redemption
Date will be payable to the Holders of such Notes, or one or more predecessor
Notes, of record at the close of business on the relevant Record Date referred
to on the face hereof.  Notes (or portions thereof) for whose redemption and
payment provision is made in accordance with the Indenture shall cease to bear
interest from and after the Redemption Date.

          (e)  Partial Redemption.  In the event of redemption of the Note in
               ------------------                                            
part only, a new Note or Notes for the unredeemed portion hereof shall be issued
in the name of the Holder hereof upon the cancellation hereof.

          5.   Offers to Purchase.  Sections 10.14 and 10.15 of the Indenture
               ------------------                                            
provide that following certain Asset Sales (with respect to Section 10.14) and
upon the occurrence of a Change of Control (with respect to Section 10.15) and
subject to further limitations contained therein, the Company shall make an
offer to purchase certain amounts of the Notes in accordance with the procedures
set forth in the Indenture.

          6.   Defaults and Remedies.  If an Event of Default shall occur and be
               ---------------------                                            
continuing, the principal of all of the outstanding Notes, plus all accrued and
unpaid interest, if any, to the date the Notes become due and payable, may be
declared due and payable in the manner and with the effect provided in the
Indenture.

          7.   Defeasance.  The Indenture contains provisions (which provisions
               ----------                                                      
apply to this Note) for defeasance at any time of (a) the entire indebtedness of
the Company on this Note and (b) certain restrictive covenants and related
Defaults and Events of Default, in each case upon compliance by the Company with
certain conditions set forth therein.

          8.   Amendments and Waivers.  The Company and the Trustee (if a party
               ----------------------                                          
thereto) may, without the consent of the Holders of any Outstanding Notes,
amend, waive or supplement the Indenture or the Notes for certain specified
purposes, including, among other things, curing ambiguities, defects or
inconsistencies, maintaining the qualification of the Indenture under the Trust
Indenture Act of 1939, as amended, and making any change that does not adversely
affect the rights of any Holder.  Other amendments and modifications of the
Indenture or the Notes may be made by the Company and the Trustee with the
consent of the Holders of not less than a majority of the aggregate principal
amount of the Outstanding Notes, subject to certain exceptions requiring the
consent of the Holders of the particular Notes to be affected.  Any such consent
or waiver by or on behalf of the Holder of this Note shall be conclusive and
binding upon such Holder and upon all future Holders of this Note and of any
Note issued upon the registration of transfer hereof or in exchange herefor or
in lieu hereof whether or not notation of such consent or waiver is made upon
this Note.

          9.   Denominations, Transfer and Exchange.  The Notes are issuable
               ------------------------------------                         
only in registered form without coupons in denominations of $1,000 and any
integral multiple thereof.  As provided in the Indenture and subject to certain
limitations therein set forth, the Notes are exchangeable for a like aggregate
principal amount of Notes of the authorized denomination, as requested by the
Holder surrendering the same.

          The transfer of this Note is registrable on the Note Register of the
Company, upon surrender of this Note for registration of transfer at the office
or agency of the Company maintained for such purpose in the Borough of Manhattan
in The City of New York or at such other office or agency of the Company as may
be maintained for such purpose, duly endorsed by, or accompanied by a written
instrument of transfer in form satisfactory to the Company and the Note
Registrar duly executed by, the Holder hereof or his attorney duly authorized in
writing, and thereupon one or more new Notes, of authorized denominations and
for the same aggregate principal amount, will be issued to the designated
transferee or transferees.

          10.  Persons Deemed Owners.  Prior to and at the time of due
               ---------------------                                  
presentment of this Note for registration of transfer, the Company, the Trustee
and any agent of the Company or the Trustee may treat the Person in whose name
this Note is registered as the owner hereof for all purposes, whether or not
this Note shall be overdue, and neither the Company, the Trustee nor any agent
shall be affected by notice to the contrary.

          11.  Registration Rights.  Pursuant to the Registration Rights
               -------------------                                      
Agreement among the Company, the Guarantors, if any, and the Initial Purchasers
for themselves and on behalf of the Holders of the Initial Notes, the Company
will be obligated to consummate an exchange offer pursuant to which the Holder
of this Note shall have the right to exchange this Note for the Company's 10
1/4% Senior Subordinated Notes due 2007, which will have been registered under
the Securities Act, in like principal amount and having terms identical in all
material respects as the Initial Notes.  The Holders of the Initial Notes shall
be entitled to receive certain additional interest payments in the event such
exchange offer is not consummated and upon certain other conditions, all
pursuant to and in accordance with the terms of the Registration Rights
Agreement.

          12.  No Recourse Against Others.  No director, officer, employee or
               --------------------------                                    
stockholder of the Company or any Guarantor, as such, shall have any liability
for any obligations of the Company or any Guarantor under the Notes, the
Guarantees or this Indenture.  Each Holder by accepting a Note waives and
releases all such liability, and such waiver and release is part of the
consideration for the issuance of the Notes.

          THE GSI GROUP, INC. a Delaware corporation (the "Company," which term
includes any successor under the Indenture hereinafter referred to), for value
received, promises to pay to _____________, or registered assigns, the principal
sum of _________ United States Dollars on November 1, 2007, at the office or
agency of the Company referred to below, and to pay interest thereon on May 1
and November 1 in each year, commencing on May 1, 1998 (each an "Interest
Payment Date"), accruing from the Issue Date or from the most recent Interest
Payment Date to which interest has been paid or duly provided for, at the rate
of 10 1/4% per annum, until the principal hereof is paid or duly provided for.
Interest shall be computed on the basis of a 360-day year of twelve 30-day
months.

          The interest so payable, and punctually paid or duly provided for, on
any Interest Payment Date will, as provided in the Indenture referred to on the
reverse hereof, be paid in arrears to the Person in whose name this Note (or one
or more predecessor Notes) is registered at the close of business on the April
15 or October 15 (each a "Regular Record Date"), whether or not a Business Day,
as the case may be, next preceding such Interest Payment Date.  Any such
interest not so punctually paid, or duly provided for, and interest on such
defaulted interest at the then applicable interest rate borne by the Notes, to
the extent lawful, shall forthwith cease to be payable to the Holder on such
Regular Record Date, and may be paid to the Person in whose name this Note (or
one or more predecessor Notes) is registered at the close of business on a
Special Record Date for the payment of such defaulted interest to be fixed by
the Trustee, notice of which shall be given to Holders of Notes not less than 10
days prior to such Special Record Date, or may be paid at any time in any other
lawful manner not inconsistent with the requirements of any securities exchange
on which the Notes may be listed, and upon such notice as may be required by
such exchange, all as more fully provided in such Indenture.

          Payment of the principal of, premium, if any, and interest on this
Note will be made at the corporate trust office or agency of the Trustee
maintained for that purpose in The City of New York, in such coin or currency of
the United States of America as at the time of payment is legal tender for
payment of public and private debts: provided, however, that payment of interest
may be made at the option of the Company by check (which may be a check of the
Company) mailed to the address of the Person entitled thereto as such address
shall appear on the Note Register.

          Reference is hereby made to the further provisions of this Note set
forth on the reverse hereof.

          Unless the certificate of authentication hereon has been duly executed
by the Trustee referred to on the reverse hereof by manual signature, this Note
shall not be entitled to any benefit under the Indenture, or be valid or
obligatory for any purpose.

                   10 1/4% Senior Subordinated Note due 2007

          1.   Indenture.  This Note is one of a duly authorized issue of Notes
               ---------                                                       
of the Company designated as its 10 1/4% Senior Subordinated Notes due 2007 (the
"Notes"), limited (except as otherwise provided in the Indenture referred to
below) in aggregate principal amount to $, which may be issued under an
indenture (the "Indenture") dated as of November 1, 1997, by and among the
Company, as Issuer and LaSalle National Bank, as trustee (the "Trustee," which
term includes any successor Trustee under the Indenture), to which Indenture and
all indentures supplemental thereto reference is hereby made for a statement of
the respective rights, limitations of rights, duties, obligations and immunities
thereunder of the Company, the Trustee and the Holders, and of the terms upon
which the Notes are, and are to be, authenticated and delivered.

          All capitalized terms used in this Note which are defined in the
Indenture and not otherwise defined herein shall have the meanings assigned to
them in the Indenture.

          No reference herein to the Indenture and no provisions of this Note or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of, premium, if any, and
interest on this Note at the times, place and rate, and in the coin or currency,
herein prescribed.

          2.   Guarantees.  This Note is entitled to certain senior subordinated
               ----------                                                       
Guarantees, if any, made for the benefit of the Holders.  Reference is hereby
made to Article Thirteen of the Indenture for terms relating to the Guarantees.

          3.   Subordination.  The Indebtedness evidenced by the Notes is, to
               -------------                                                 
the extent and in the manner provided in the Indenture, subordinate and subject
in right of payment to the prior payment in full in cash of all existing and
future Senior Indebtedness (including the Indebtedness under the New Credit
Agreement).  Each Holder, by accepting the same, (a) agrees to and shall be
bound by such provisions, (b) authorizes and directs the Trustee, on behalf of
such Holder, to take such action as may be necessary or appropriate to
effectuate the subordination as provided in the Indenture and (c) appoints the
Trustee attorney-in-fact of such Holder for such purpose; provided, however,
that the Indebtedness evidenced by this Note shall cease to be so subordinate
and subject in right of payment upon any defeasance of this Note referred to in
Paragraph 7 below.

          4.   Redemption.
               ---------- 

          (a)  Optional Redemption.  Subject to earlier redemption in the manner
               -------------------                                              
described in the next two succeeding paragraphs, the Notes will be redeemable at

set forth below, plus accrued and unpaid interest, if any, to the date of

          2002                      105.188%

          On or prior to November 1, 2000, the Company may, at its option, use
the net proceeds of an Equity Offering to redeem up to 35% of the originally
issued aggregate principal amount of the Notes, at a redemption price in cash
equal to 110 1/4% of the principal amount thereof, plus accrued and unpaid
interest thereon, if any, to the date of redemption; provided, however, that not
less than $65.0 million in aggregate principal amount of Notes is outstanding
following such redemption. Notice of any such redemption must be given not later
than 60 days after the consummation of the Equity Offering.

          As used in the preceding paragraph, an ''Equity Offering'' means any
public or private sale of equity securities (other than Redeemable Capital
Stock) of the Company; provided, however, that the proceeds (net of any
underwriting discounts or commissions) to the Company from any such private sale
of equity securities shall be at least $20.0 million.

          (b)  Redemption Upon Change of Control.  Following the occurrence of a
               ---------------------------------                                
Change of Control (the date of such occurrence being the ''Change of Control
Date''), the Company will be obligated, not more than 40 or less than 20
business days after the Change of Control Date, to make an offer to purchase (a
''Change of Control Offer'') all of the then outstanding Notes at a purchase
price (the ''Change of Control Purchase Price'') in cash equal to 101% of the
principal amount thereof, plus accrued and unpaid interest thereon, if any, to
the purchase date. The Company will be required to purchase all Notes properly
tendered into the Change of Control Offer and not withdrawn.

          In order to effect such Change of Control Offer, the Company will, not
later than the 40th business day after the Change of Control Date, be obligated
to mail to each holder of Notes notice of the Change of Control Offer, which
notice will govern the terms of the Change of Control Offer and will state,
among other things, the procedures that holders must follow to accept the Change
of Control Offer. The Change of Control Offer will be required to be kept open
for a period of at least 20 business days.

          (c)  Sinking Fund.  The Company will not be required to make any
               ------------                                               
mandatory sinking fund payments in respect of the Notes.

          (d)  Interest Payments.  In the case of any redemption of the Notes,
               -----------------                                              
interest installments whose Stated Maturity is on or prior to the Redemption
Date will be payable to the Holders of such Notes, or one or more predecessor
Notes, of record at the close of business on the relevant Record Date referred
to on the face hereof.  Notes (or portions thereof) for whose redemption and
payment provision is made in accordance with the Indenture shall cease to bear
interest from and after the Redemption Date.

          (e)  Partial Redemption.  In the event of redemption of the Note in
               ------------------                                            
part only, a new Note or Notes for the unredeemed portion hereof shall be issued
in the name of the Holder hereof upon the cancellation hereof.

          5.   Offers to Purchase.  Sections 10.14 and 10.15 of the Indenture
               ------------------                                            
provide that following certain Asset Sales (with respect to Section 10.14) and
upon the occurrence of a Change of Control (with respect to Section 10.15) and
subject to further limitations contained therein, the Company shall make an
offer to purchase certain amounts of the Notes in accordance with the procedures
set forth in the Indenture.

          6.   Defaults and Remedies.  If an Event of Default shall occur and be
               ---------------------                                            
continuing, the principal of all of the outstanding Notes, plus all accrued and
unpaid interest, if any, to the date the Notes become due and payable, may be
declared due and payable in the manner and with the effect provided in the
Indenture.

          7.   Defeasance.  The Indenture contains provisions (which provisions
               ----------                                                      
apply to this Note) for defeasance at any time of (a) the entire indebtedness of
the Company on this Note and (b) certain

<PAGE>
 
restrictive covenants and related Defaults and Events of Default, in each case
upon compliance by the Company with certain conditions set forth therein.

          8.   Amendments and Waivers.  The Company and the Trustee (if a party
               ----------------------                                          
thereto) may, without the consent of the Holders of any Outstanding Notes,
amend, waive or supplement the Indenture or the Notes for certain specified
purposes, including, among other things, curing ambiguities, defects or
inconsistencies, maintaining the qualification of the Indenture under the Trust
Indenture Act of 1939, as amended, and making any change that does not adversely
affect the rights of any Holder.  Other amendments and modifications of the
Indenture or the Notes may be made by the Company and the Trustee with the
consent of the Holders of not less than a majority of the aggregate principal
amount of the Outstanding Notes, subject to certain exceptions requiring the
consent of the Holders of the particular Notes to be affected.  Any such consent
or waiver by or on behalf of the Holder of this Note shall be conclusive and
binding upon such Holder and upon all future Holders of this Note and of any
Note issued upon the registration of transfer hereof or in exchange herefor or
in lieu hereof whether or not notation of such consent or waiver is made upon
this Note.

          9.   Denominations, Transfer and Exchange.  The Notes are issuable
               ------------------------------------                         
only in registered form without coupons in denominations of $1,000 and any
integral multiple thereof.  As provided in the Indenture and subject to certain
limitations therein set forth, the Notes are exchangeable for a like aggregate
principal amount of Notes of the authorized denomination, as requested by the
Holder surrendering the same.

          The transfer of this Note is registrable on the Note Register of the
Company, upon surrender of this Note for registration of transfer at the office
or agency of the Company maintained for such purpose in the Borough of Manhattan

instrument of transfer in form satisfactory to the Company and the Note
Registrar duly executed by, the Holder hereof or his attorney duly authorized in
writing, and thereupon one or more new Notes, of authorized denominations and
for the same aggregate principal amount, will be issued to the designated
transferee or transferees.

          10.  Persons Deemed Owners.  Prior to and at the time of due

presentment of this Note for registration of transfer, the Company, the Trustee
and any agent of the Company or the Trustee may treat the Person in whose name
this Note is registered as the owner hereof for all purposes, whether or not
this Note shall be overdue, and neither the Company, the Trustee nor any agent
shall be affected by notice to the contrary.

          11.  No Recourse Against Others.  No director, officer or employee or
               --------------------------                                      
stockholder of the Company or any Guarantor, as such, shall have any liability
for any obligations of the Company or any Guarantor under the Notes, the
Guarantees or the Indenture.  Each Holder of Notes by accepting a Note waives
and releases all such liability, and such waiver and release is part of the
consideration for the issuance of the Notes.

          -------------------------------------------------------- 

Ladies and Gentlemen:

          In connection with our proposed purchase of $_______ aggregate
principal amount of the Notes, we confirm that:

          1.   We understand that any subsequent transfer of the Notes is
     subject to certain restrictions and conditions set forth in the Indenture
     dated as of November 1, 1997 relating to the Notes (the "Indenture") and
     the undersigned agrees to be bound by, and not to resell, pledge or
     otherwise transfer the Notes except in compliance with, such restrictions
     and conditions and the Securities Act of 1933, as amended (the "Securities
     Act").

          2.   We understand that the Notes have not been registered under the
     Securities Act, and that the Notes may not be offered or sold except as
     permitted in the following sentence. We agree, on our own behalf and on
     behalf of any accounts for which we are acting as hereinafter stated, that
     if we should sell any Notes within two years after the original issuance of
     the Notes, we will do so only (A) to the Company or any subsidiary thereof,
     (B) inside the United States in accordance with Rule 144A under the
     Securities Act to a "qualified institutional buyer" (as defined therein),
     (C) inside the United States to an "institutional accredited investor" (as
     defined below) that, prior to such transfer, furnishes (or has furnished on
     its behalf by a U.S. broker-dealer) to you a signed letter substantially in
     the form of this letter, (D) outside the United States in accordance with
     Rule 904 of RegulationS under the Securities Act, (E) pursuant to an
     effective registration statement under the Securities Act, and we further
     agree to provide to any person purchasing any of the Notes from us a notice
     advising such purchaser that resales of the Notes are restricted as stated
     herein, or (F) pursuant to another available exemption from the
     registration requirements of the Securities Act.

          3.   We understand that, on any proposed resale of any Notes, we will
     be required to furnish to you and the Company such certification, written
     legal opinions and other information as you and the Company may reasonably
     require to confirm that the proposed sale complies with the foregoing
     restrictions.  We further understand that the Notes purchased by us will
     bear a legend to the foregoing effect.

          4.   We are an institutional "accredited investor" (as defined in Rule
     501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act) and
     have such knowledge and experience in financial and business matters as to
     be capable of evaluating the merits and risks of our investment in the
     Notes, and we and any accounts for which we are acting are each able to
     bear the economic risk of our or its investment, as the case may be.

          The Exchange Securities and the Private Exchange Securities shall be
issued under (i) the Indenture or (ii) an indenture identical to all material
respects to the Indenture and which, in either case, has been qualified under
the TIA or is exempt from such qualification and shall provide that the Exchange
Securities shall not be subject to the transfer restrictions set forth in the
Indenture. The Indenture or such indenture shall provide that the Exchange
Securities, the Private Exchange Securities and the Securities shall vote and
consent together on all matters as one class and that none of the Exchange
Securities, the Private Exchange Securities or the Securities will have the
right to vote or consent as a separate class on any matter. The Private Exchange
Securities shall be of the same series as, and the Company shall use all
commercially reasonable efforts to have the Private Exchange Securities bear the
same CUSIP number as, the Exchange Securities. Neither the Company nor any of
its Subsidiaries shall have any liability under this Agreement solely as a
result of such Private Exchange Securities not bearing the same CUSIP number as
the Exchange Securities.

any conditions, other than that (i) the Exchange Offer or Private Exchange, as
the case may be, does not violate applicable law or any applicable policy of the

any court or by any governmental agency which might materially impair the
ability of the Company to proceed with the Exchange Offer or the Private
Exchange, and no material adverse development shall have occurred in any
existing action or proceeding with respect to the Company, (iii) all
governmental approvals shall have been obtained, which approvals the Company
deems

                                      -9-

necessary for the consummation of the Exchange Offer or Private Exchange
and (iv) the due tendering of Registrable Securities in accordance with the
terms of the Exchange Offer.  As soon as practicable after the close of the
Exchange Offer and/or the Private Exchange, as the case may be, the Company
shall:

          (i)  accept for exchange all Registrable Securities or portions
     thereof properly tendered and not validly withdrawn pursuant to the
     Exchange Offer in accordance with the terms of the Exchange Offer
     Registration Statement and the letter of transmittal that is an exhibit
     thereto;

         (ii)  accept for exchange all Securities properly tendered pursuant to
     the Private Exchange; and

        (iii)  deliver, or cause to be delivered, to the Trustee for
     cancellation all Registrable Securities or portions thereof so accepted for
     exchange by the Company, and issue, and cause the Trustee under the
     Indenture to promptly authenticate and deliver to each Holder, a new
     Exchange Security or Private Exchange Security, as the case may be, equal
     in principal amount to the principal amount of the Registrable Securities
     surrendered by such Holder and accepted for exchange.

          To the extent not prohibited by any law or applicable policy of the
SEC, the Company shall use its best efforts to complete the Exchange Offer as
provided above, and shall comply with the applicable requirements of the
Securities Act, the Exchange Act and other applicable laws in connection with
the Exchange Offer. The Exchange Offer shall not be subject to any conditions,
other than those set forth in the immediately preceding paragraph. Each Holder
of Registrable Securities (other than Private Exchange Securities) who wishes to
exchange such Registrable Securities for Exchange Securities in the Exchange
Offer will be required to make certain customary representations in connection
therewith, including representations that such Holder is not an affiliate of the
Company within the meaning of Rule 405 under the Securities Act, that it is not
a broker-dealer tendering Registrable Securities acquired directly from the
Company for its own account, that any Exchange Securities to be received by it
will be acquired in the ordinary course of business and that at the time of the
commencement of the Exchange Offer it has no arrangement or understanding with
any Person to participate in the distribution (within the meaning of the
Securities Act) of the Exchange Securities. The Company shall inform the Initial
Purchasers of the names and

addresses of the Holders to whom the Exchange Offer is made, and the Initial
Purchasers shall have the right to contact such Holders and otherwise facilitate

mutandis, solely with respect to Registrable Securities that are Private

Commission policy, (ii) the Exchange Offer is not for any other reason
consummated within 180 days after the Issue Date, (iii) any holder of Securities
notifies the Company within 20 Business Days after the commencement of the
Exchange Offer that (a) due to a change in applicable law or SEC policy it is
not entitled to participate in the Exchange Offer, (b) due to a change in
applicable law or SEC policy it may not resell the Exchange Securities to be
acquired by it in the Exchange Offer to the public without delivering a
prospectus and the prospectus contained in the Exchange Offer Registration
Statement is not appropriate or available for such resales by such holder or (c)
it is a broker-dealer and owns Securities acquired directly from the Company for
its own account or (iv) the holders of a majority of the Securities may not
resell the Exchange Securities to be acquired by them in the Exchange Offer to
the public without restriction under the Securities Act (other than the delivery
of the Prospectus included in the Exchange Offer Registration Statement), then
the Company shall, at its cost, use its best efforts to cause to be filed as
promptly as practicable after such determination or date, as the case may be,
and, in any event, prior to the later of (A) 120 days after the Issue Date or
(B) 30 days after such filing obligation arises and use its best efforts to
cause the Shelf Registration Statement to be declared effective by the SEC on or
prior to 60 days after such obligation arises; provided, however, that if the
Company has not consummated the Exchange Offer within 180 days of the Issue
Date, then the Company will file with the SEC on or prior to the 181st day after
the Issue Date, a Shelf Registration Statement providing for the sale by the
Holders of all of the Registrable Securities, and shall use its best efforts to
<PAGE>
 
                                     -11-

have such Shelf Registration Statement declared effective by the SEC as soon as
practicable. No Holder of Registrable Securities may include any of its
Registrable Securities in any Shelf Registration pursuant to this Agreement
unless and until such Holder furnishes to the Company in writing, within 15 days
after receipt of a request therefor, such information as the Company may, after
conferring with counsel with regard to information relating to Holders that
would be required by the SEC to be included in such Shelf Registration Statement
or Prospectus included therein, reasonably request for inclusion in any Shelf
Registration Statement or Prospectus included therein. Each Holder as to which
any Shelf Registration is being effected agrees to furnish to the Company all
information with respect to such Holder necessary to make any information
previously furnished to the Company by such Holder not materially misleading.

          The Company agrees to use its best efforts to keep the Shelf
Registration Statement continuously effective for a period of two years from the
Issue Date (subject to extension pursuant to the last paragraph of Section 3
hereof) (or such shorter period that will terminate when all of the Registrable
Securities covered by such Shelf Registration Statement have been sold pursuant
thereto) or cease to be outstanding (the "Effectiveness Period"); provided,
                                          --------------------             
however, that if such Shelf Registration Statement has been filed solely at the
request of any Initial Purchasers pursuant to clause (iv) above, the Company
shall only be required to use its best efforts to keep such Shelf Registration
Statement continuously effective for a period of one year from the Issue Date
(subject to extension pursuant to the last paragraph of Section 3 hereof) or for
such shorter period which will terminate when all of the Registrable Securities
covered by the Shelf Registration Statement have been sold pursuant to the Shelf
Registration Statement or cease to be outstanding. The Company shall not permit
any securities other than Registrable Securities to be included in the Shelf
Registration. The Company further agrees, if necessary, to supplement or amend
the Shelf Registration Statement, if required by the rules, regulations or
instructions applicable to the registration form used by the Company for such
Shelf Registration Statement or by the Securities Act or by any other rules and
regulations thereunder for shelf registrations, and the Company agrees to
furnish to the Holders of Registrable Securities copies of any such supplement
or amendment promptly after its being used or filed with the SEC.

          (c)  Expenses.  The Company shall pay all Registration Expenses in
               --------                                                     
connection with the registration pursuant to 
<PAGE>
 
                                     -12-

Section 2(a) or 2(b) hereof and the reasonable fees and expenses of one counsel,
if any, designated in writing by the Majority Holders to act as counsel for the
Holders of the Registrable Securities in connection with a Shelf Registration
Statement. Except as provided in the preceding sentence, each Holder shall pay
all expenses of its counsel, underwriting discounts and commissions and transfer
taxes, if any, relating to the sale or disposition of such Holder's Registrable
Securities pursuant to the Shelf Registration Statement.

          (d)  Effective Registration Statement.  An Exchange Offer Registration
               --------------------------------                                 
Statement pursuant to Section 2(a) hereof or a Shelf Registration Statement
pursuant to Section 2(b) hereof will not be deemed to have become effective
unless it has been declared effective by the SEC; provided, however, that if,
after it has been declared effective, the offering of Registrable Securities
pursuant to a Shelf Registration Statement is interfered with by any stop order,
injunction or other order or requirement of the SEC or any other governmental
agency or court, such Registration Statement will be deemed not to have been
effective during the period of such interference, until the offering of
Registrable Securities may legally resume.  The Company will be deemed not to
have used its best efforts to cause the Exchange Offer Registration Statement or
the Shelf Registration Statement, as the case may be, to become, or to remain,
effective during the requisite period if it voluntarily takes any action that
would result in any such Registration Statement not being declared effective or
in the Holders of Registrable Securities covered thereby not being able to
exchange or offer and sell such Registrable Securities during that period,
unless such action is required by applicable law or unless such action is taken
by the Company in good faith and for valid business reasons, including the
acquisition or divestiture of assets, so long as the Company promptly thereafter
complies with the requirements of Section 3(b) hereof, if applicable.

          (e)  Additional Interest.  In the event that (i) the applicable
               -------------------                                       
Registration Statement is not filed with the SEC on or prior to the date
specified herein for such filing, (ii) the applicable Registration Statement is
not declared effective on or prior to the date specified herein for such
effectiveness after such obligation arises (the "Effectiveness Target Date"),
                                                 -------------------------   
(iii) if the Exchange Offer is required to be consummated hereunder, the Company
fails to consummate the Exchange Offer within 30 Business Days of the
Effectiveness Target Date with respect to the Exchange Offer Registration
Statement or (iv) the applicable Registration Statement is filed and declared
effective prior to the Effectiveness Target Date but 
<PAGE>
 
                                     -13-

shall thereafter cease to be effective or usable without being succeeded
immediately by an additional Registration Statement covering the Registrable
Securities which has been filed and declared effective (each such event referred
to in clauses (i) through (iv), a "Registration Default"), then the interest
                                   -------------------- 
rate on the Registrable Securities as to which such Registration Default relates
will increase ("Additional Interest"), with respect to the first 90-day period
                -------------------
(or portion thereof) while a Registration Default is continuing immediately
following the occurrence of such Registration Default, in an amount equal to
0.25% per annum of the principal amount of the Securities. The rate of
additional Interest will increase by an additional 0.25% per annum of the
principal amount of the Securities for each subsequent 90-day period (or portion
thereof) while a Registration Default is continuing until all Registration
Defaults have been cured, up to an aggregate maximum increase in the interest
rate of 1.00% per annum of the principal amount of the Securities. Additional
Interest shall be computed based on the actual number of days elapsed during
which any such Registration Defaults exist. Following the cure of a Registration
Default, the accrual of Additional Interest with respect to such Registration
Default will cease and the interest will revert to the original rate.

          The Company shall notify the Trustee within three Business Days after
each and every date on which an event occurs in respect of which Additional
Interest is required to be paid (an "Event Date").  Additional Interest shall be
                                     ----------                                 
paid in arrears by depositing with the Trustee, in trust, for the benefit of the
Holders of Registrable Securities, on or before the applicable semiannual
interest payment date, immediately available funds in sums sufficient to pay the
Additional Interest then due.  The Additional Interest due shall be payable in
arrears on each interest payment date to the record Holder of Securities
entitled to receive the interest payment to be paid on such date as set forth in
the Indenture.  Each obligation to pay Additional Interest shall be deemed to
accrue from and including the day following the applicable Event Date.

          (f)  Specific Enforcement.  Without limiting the remedies available to
               --------------------                                             
the Initial Purchasers and the Holders, the Company acknowledges that any
failure by the Company to comply with its obligations under Section 2(a) and
Section 2(b) hereof may result in material irreparable injury to the Initial
Purchasers or the Holders for which there is no adequate remedy at law, that it
would not be possible to measure damages for such injuries precisely and that,
in the event of any such failure, the Initial Purchasers or any Holder may
obtain such 
<PAGE>
 
                                     -14-

relief as may be required to specifically enforce the Company's obligations
under Section 2(a) and Section 2(b) hereof.

          3.   Registration Procedures.  In connection with the obligations of
               -----------------------                                        
the Company with respect to the Registration Statements pursuant to Sections
2(a) and 2(b) hereof, the Company shall:

          (a)  prepare and file with the SEC a Registration Statement or
     Registration Statements as prescribed by Sections 2(a) and 2(b) hereof
     within the relevant time period specified in Section 2 hereof on the
     appropriate form under the Securities Act, which form (i) shall be selected
     by the Company, (ii) shall, in the case of a Shelf Registration, be
     available for the sale of the Registrable Securities by the selling Holders
     thereof and (iii) shall comply as to form in all material respects with the
     requirements of the applicable form and include all financial statements
     required by the SEC to be filed therewith; and use its best efforts to
     cause such Registration Statement to become effective and remain effective
     in accordance with Section 2 hereof. The Company shall not file any
     Registration Statement or Prospectus or any amendments or supplements
     thereto in respect of which the Holders must provide information for
     inclusion therein without the Holders being afforded an opportunity to
     review such documentation a reasonable time prior to the filing of such
     document or if the Majority Holders or such Participating Broker-Dealer, as
     the case may be, their counsel or the managing underwriters, if any, shall
     reasonably object by written notice to the Company within three Business
     Days after receipt of such documentation;

          (b)  prepare and file with the SEC such amendments and post-effective
     amendments to each Registration Statement as may be necessary to keep such
     Registration Statement effective for the Effectiveness Period or the
     Applicable Period, as the case may be; and cause each Prospectus to be
     supplemented by any required prospectus supplement and as so supplemented
     to be filed pursuant to Rule 424 (or any similar provision then in force)
     under the Securities Act, and comply with the provisions of the Securities
     Act, the Exchange Act and the rules and regulations promulgated thereunder
     applicable to it with respect to the disposition of all securities covered
     by each Registration Statement during the Effectiveness Period or the
     Applicable Period, as the case may be, in accordance with the intended
     method or methods of distribution by the 
<PAGE>
 
                                     -15-

     selling Holders thereof described in this Agreement (including sales by any
     Participating Broker-Dealer);

          (c)  in the case of a Shelf Registration, (i) furnish to each Holder
     of Registrable Securities, without charge, as many copies of each
     Prospectus, and any amendment or supplement thereto and such other
     documents as such Holder may reasonably request, in order to facilitate the
     disposition of the Registrable Securities and (ii) subject to the last
     paragraph of Section 3 hereof, hereby consent to the use of the Prospectus
     or any amendment or supplement thereto by each of the selling Holders of
     Registrable Securities in connection with the offering and sale of the
     Registrable Securities covered by such Prospectus or any amendment or
     supplement thereto subject to the limitations on the use thereof provided
     in Sections 2(b) and 2(c);

          (d)  in the case of a Shelf Registration, use its best efforts to
     register or qualify, as may be required by applicable law, the Registrable
     Securities under all applicable state securities or "blue sky" laws of such
     jurisdictions by the time the applicable Registration Statement is declared
     effective by the SEC as any Holder of Registrable Securities covered by a
     Registration Statement shall reasonably request in advance of such date of
     effectiveness, and do any and all other acts and things which may be
     reasonably necessary or advisable to enable such Holder to consummate the
     disposition in each such jurisdiction of such Registrable Securities owned
     by such Holder; provided, however, that the Company shall not be required
     to (i) qualify as a foreign corporation or as a broker or dealer in
     securities in any jurisdiction where it would not otherwise be required to
     qualify but for this Section 3(d), (ii) file any general consent to service
     of process or (iii) subject itself to taxation in any such jurisdiction if
     it is not so subject;

          (e)  in the case of (1) a Shelf Registration or (2) Participating
     Broker-Dealers who have notified the Company that they will be utilizing
     the Prospectus contained in the Exchange Offer Registration Statement as
     provided in Section 3(s) hereof, notify each Holder of Registrable
     Securities, or such Participating Broker-Dealers, as the case may be, their
     counsel, if any, promptly and if requested by such Holder or Participating
     Broker-Dealer confirm such notice in writing (i) when a Registration
     Statement has become effective and when any post-effective amendments and
     supplements thereto become 
<PAGE>
 
                                     -16-

     effective, (ii) of any request by the SEC or any state securities authority
     for amendments and supplements to a Registration Statement or Prospectus or
     for additional information after the Registration Statement has become
     effective, (iii) of the issuance by the SEC or any state securities
     authority of any stop order suspending the effectiveness of a Registration
     Statement or the initiation of any proceedings for that purpose, (iv) if
     the Company receives any notification with respect to the suspension of the
     qualification of the Registrable Securities or the Exchange Securities to
     be sold by any Participating Broker-Dealer for offer or sale in any
     jurisdiction or the initiation of any proceeding for such purpose, (v) of
     the happening of any event or the failure of any event to occur or the
     discovery of any facts or otherwise, during the period a Shelf Registration
     Statement is effective which makes any statement made in such Registration
     Statement or the related Prospectus untrue in any material respect or which
     causes such Registration Statement or Prospectus to omit to state a
     material fact necessary to make the statements therein, in the light of the
     circumstances under which they were made, not misleading and (vi) the
     Company's reasonable determination that a post-effective amendment to the
     Registration Statement would be appropriate;

          (f)  make every reasonable effort to obtain the withdrawal of any
     order suspending the effectiveness of a Registration Statement as soon as
     practicable;

          (g)  in the case of a Shelf Registration, furnish to each Holder of
     Registrable Securities, without charge, at least one conformed copy of each
     Registration Statement relating to such Shelf Registration and any post-
     effective amendment thereto (without documents incorporated therein by
     reference or exhibits thereto, unless requested);

          (h)  in the case of a Shelf Registration, cooperate with the selling
     Holders of Registrable Securities to facilitate the timely preparation and
     delivery of certificates not bearing any restrictive legends representing
     Securities covered by such Shelf Registration to be sold and relating to
     the subsequent transfer of such Securities; and cause such Registrable
     Securities to be in such denominations (consistent with the provisions of
     the Indenture) and registered in such names as the selling Holders may
     reasonably request at least two Business Days prior to the closing of any
     sale of Registrable Securities;
<PAGE>
 
                                     -17-

          (i)  in the case of a Shelf Registration or an Exchange Offer
     Registration, upon the occurrence of any circumstance contemplated by
     Section 3(e)(ii), 3(e)(iii), 3(e)(iv), 3(e)(v) or 3(e)(vi) hereof, use its
     best efforts to prepare a supplement or post-effective amendment to a
     Registration Statement or the related Prospectus or any document
     incorporated therein by reference or file any other required document so
     that, as thereafter delivered to the purchasers of the Registrable
     Securities, such Prospectus will not contain any untrue statement of a
     material fact or omit to state a material fact necessary to make the
     statements therein, in the light of the circumstances under which they were
     made, not misleading; and to notify each Holder to suspend use of the
     Prospectus as promptly as practicable after the occurrence of such an
     event, and each Holder hereby agrees to suspend use of the Prospectus until
     the Company has amended or supplemented the Prospectus to correct such
     misstatement or omission;

          (j)  obtain a CUSIP number for all Exchange Securities or Registrable
     Securities, as the case may be, not later than the effective date of a
     Registration Statement, and provide the Trustee with certificates for the
     Exchange Securities or the Registrable Securities, as the case may be, in a
     form eligible for deposit with the Depositary;

          (k)  cause the Indenture to be qualified under the Trust Indenture Act
     of 1939, as amended, (the "TIA") in connection with the registration of the
                                ---                                         
     Exchange Securities or Registrable Securities, as the case may be,
     cooperate with the Trustee and the Holders to effect such changes to the
     Indenture as may be required for the Indenture to be so qualified in
     accordance with the terms of the TIA and execute, and use its best efforts
     to cause the Trustee to execute, all documents as may be required to effect
     such changes, and all other forms and documents required to be filed with
     the SEC to enable the Indenture to be so qualified in a timely manner;

          (l)  in the case of a Shelf Registration, enter into such agreements
     and take all such other appropriate actions as are reasonably requested in
     order to expedite or facilitate the registration or the disposition of such
     Registrable Securities, and in such connection, (i) make such
     representations and warranties to Holders of such Registrable Securities
     with respect to the business of the Company and its subsidiaries as then
     conducted and the Registration Statement, Prospectus and documents, if any,

     incorporated or deemed to be incorporated by reference therein, in each
     case, as are customarily made by issuers to underwriters in underwritten
     offerings, and confirm the same if and when requested; (ii) obtain opinions
     of counsel to the Company and updates thereof in form and substance
     reasonably satisfactory to the Holders of a majority in principal amount of
     the Registrable Securities covered by such Registration Statement,
     addressed to each selling Holder covering the matters customarily covered
     in opinions requested in underwritten offerings and such other matters as
     may be reasonably requested by such Holders; (iii) obtain "cold comfort"
     letters and updates thereof from the independent certified public
     accountants of the Company (and, if necessary, any other independent
     certified public accountants of any subsidiary of the Company or of any
     business acquired by the Company for which financial statements and
     financial data are, or are required to be, included in the Registration
     Statement), addressed to the Company and the selling Holders of Registrable
     Securities (other than Participating Broker-Dealers, unless such
     Participating Broker-Dealers would be deemed to be "underwriters" as a
     result of the sale of Securities covered by such Shelf Registration
     Statement), such letters to be in customary form and covering matters of
     the type customarily covered in "cold comfort" letters in connection with

     such selling Holders; and (iv) if an underwriting agreement is entered
     into, the same shall contain indemnification provisions and procedures no
     less favorable than those set forth in Section 4 hereof (or such other
     provisions and procedures acceptable to the Company and the Holders of a
     majority in aggregate principal amount of Registrable Securities covered by
     such Registration Statement) with respect to all parties to be indemnified
     pursuant to said Section (including, without limitation, such selling
     Holders). The above shall be done at each closing in respect of the sale of
     Registrable Securities, or as and to the extent required thereunder;

          (m)  if (1) a Shelf Registration is filed pursuant to Section 2(b) or
     (2) a Prospectus contained in an Exchange Offer Registration Statement
     filed pursuant to Section 2(a) is required to be delivered under the
     Securities Act by any Participating Broker-Dealer who seeks to sell
     Exchange Securities during the Applicable Period, make available for

     tion Statement or (ii) the sale during the Applicable Period by a
     Participating Broker-Dealer of Exchange Securities (provided that a
     Participating Broker-Dealer shall not be deemed to be an underwriter solely
     as a result of it being required to deliver a prospectus in connection with
     any resale of Exchange Securities) and any attorney, accountant or other
     agent retained by any such person (collectively, the "Inspectors"), at the
                                                           ----------

     financial and other records, pertinent corporate documents and properties
     of the Company and its subsidiaries (collectively, the "Records") as shall

     be reasonably necessary to enable them to exercise any applicable due
     diligence responsibilities, and cause the officers, directors and employees
     of the Company and its subsidiaries to supply all information in each case
     reasonably requested by any such Inspector in connection with such
     Registration Statement. Records which the Company determines, in good
     faith, to be confidential and any Records which it notifies the Inspectors
     are confidential shall not be disclosed by the Inspectors to any other
     Person unless (i) the disclosure of such Records is necessary to avoid or
     correct a material misstatement or omission in such Registration Statement,
     (ii) the release of such Records is ordered pursuant to a subpoena or other
     order from a court of competent jurisdiction or (iii) the information in
     such Records has been made generally available to the public through no
     fault or action of any selling Holder of such Registrable Securities, any
     such Participating Broker-Dealer or any Inspector. Each such Holder and
     each such Participating Broker-Dealer will be required to agree that
     information obtained by it as a result of such inspections shall be deemed
     confidential and shall not be used by it as the basis for any market
     transactions in the securities of the Company unless and until such is made
     generally available to the public through no fault or action of such
     Holder, such Participating Broker-Dealer or any Inspector. Each selling
     Holder of such Registrable Securities and each such Participating Broker-
     Dealer will be required to further agree that it will, upon learning that
     disclosure of such Records is necessary under (i) or (ii) above, give
     notice to the Company and allow the Company at its expense to undertake
     appropriate action to prevent disclosure of the Records deemed
     confidential;

          (n)  comply with all applicable rules and regulations of the SEC and
     make generally available to its securityholders earnings statements
     satisfying the provisions of 
<PAGE>
 
                                     -20-

     Section 11(a) of the Securities Act and Rule 158 thereunder (or any similar
     rule promulgated under the Securities Act) no later than 45 days after the
     end of any 12-month period (or 90 days after the end of any 12-month period
     if such period is a fiscal year) (i) commencing at the end of any fiscal
     quarter in which Registrable Securities are sold to underwriters in a firm
     commitment or best efforts underwritten offering and (ii) if not sold to
     underwriters in such an offering, commencing on the first day of the first
     fiscal quarter of the Company after the effective date of a Registration
     Statement, which statements shall cover said 12-month periods;

          (o)  upon consummation of an Exchange Offer or a Private Exchange,
     obtain an opinion of counsel to the Company addressed to the Trustee for
     the benefit of all Holders of Registrable Securities participating in the
     Exchange Offer or the Private Exchange, as the case may be, and which
     includes an opinion that (i) the Company has duly authorized, executed and
     delivered the Exchange Securities and Private Exchange Securities, and (ii)
     each of the Exchange Securities or the Private Exchange Securities, as the
     case may be, constitute a legal, valid and binding obligation of the
     Company, enforceable against the Company in accordance with its respective
     terms (in each case, with customary exceptions);

          (p)  if an Exchange Offer or a Private Exchange is to be consummated,
     upon proper delivery of the Registrable Securities by Holders to the
     Company (or to such other Person as directed by the Company) in exchange
     for the Exchange Securities or the Private Exchange Securities, as the case
     may be, the Company shall mark, or cause to be marked, on such Registrable
     Securities and on the books of the Trustee, the Note Registrar (as defined
     in the Indenture) and, if necessary, the Depositary, delivered by such
     Holders that such Registrable Securities are being canceled in exchange for
     the Exchange Securities or the Private Exchange Securities, as the case may
     be; but in no event shall such Registrable Securities be marked as paid or
     otherwise satisfied solely as a result of being exchanged for Exchange
     Securities or Private Exchange Securities in the Exchange Offer or the
     Private Exchange, as the case may be;

          (q)  cooperate with each seller of Registrable Securities covered by
     any Registration Statement participating in the disposition of such
     Registrable Securities and one 
<PAGE>
 
                                     -21-

     counsel acting on behalf of all such sellers in connection with the
     filings, if any, required to be made with the NASD;

          (r)  use its best efforts to take all other steps necessary to effect
     the registration of the Registrable Securities covered by a Registration
     Statement contemplated hereby; and

          (s)  (A)  in the case of the Exchange Offer Registration Statement (i)
     include in the Exchange Offer Registration Statement a section entitled
     "Plan of Distribution," which section shall be reasonably acceptable to
     Merrill Lynch, as representative of the Initial Purchasers, and which shall
     contain a summary statement of the positions taken or policies made by the
     staff of the SEC with respect to the potential "underwriter" status of any
     broker-dealer (a "Participating Broker-Dealer") that holds Registrable
                       ---------------------------                         
     Securities acquired for its own account as a result of market-making
     activities or other trading activities and that will be the beneficial
     owner (as defined in Rule 13d-3 under the Exchange Act) of Exchange
     Securities to be received by such broker-dealer in the Exchange Offer,
     whether such positions or policies have been publicly disseminated by the
     staff of the SEC or such positions or policies, in the reasonable judgment
     of Merrill Lynch, as representative of the Initial Purchasers or such other
     representative, represent the prevailing views of the staff of the SEC,
     including a statement that any such Participating Broker-Dealer who
     receives Exchange Securities for Registrable Securities pursuant to the
     Exchange Offer may be deemed a statutory underwriter and must deliver a
     prospectus meeting the requirements of the Securities Act in connection
     with any resale of such Exchange Securities, (ii) furnish to each
     Participating Broker-Dealer who has delivered to the Company the notice
     referred to in Section 3(e), without charge, as many copies of each
     Prospectus included in the Exchange Offer Registration Statement, and any
     amendment or supplement thereto, as such Participating Broker-Dealer may
     reasonably request; (iii) hereby consent to the use of the Prospectus
     forming part of the Exchange Offer Registration Statement or any amendment
     or supplement thereto, by any Person subject to the prospectus delivery
     requirements of the SEC, including all Participating Broker-Dealers, in
     connection with the sale or transfer of the Exchange Securities covered by
     the Prospectus or any amendment or supplement thereto, (iv) use its best
     efforts to keep the Exchange Offer Registration Statement 
<PAGE>
 
                                     -22-

     effective and to amend and supplement the Prospectus contained therein in
     order to permit such Prospectus to be lawfully delivered by all Persons
     subject to the prospectus delivery requirements of the Securities Act for
     such period of time as such Persons must comply with such requirements in
     order to resell the Exchange Securities; provided, however, that such
     period shall not be required to exceed 90 days (or such longer period if
     extended pursuant to the last sentence of Section 3 hereof) (the
     "Applicable Period"), and (iv) include in the transmittal letter or similar
      -----------------            
     documentation to be executed by an exchange offeree in order to participate
     in the Exchange Offer (x) the following provision:

          "If the exchange offeree is a broker-dealer holding
          Registrable Securities acquired for its own account as a
          result of market-making activities or other trading
          activities, it will deliver a prospectus meeting the
          requirements of the Securities Act in connection with any
          resale of Exchange Securities received in respect of such
          Registrable Securities pursuant to the Exchange Offer";

     and (y) a statement to the effect that by a broker-dealer making the
     acknowledgment described in clause (x) and by delivering a Prospectus in
     connection with the exchange of Registrable Securities, such broker-dealer
     will not be deemed to admit that it is an underwriter within the meaning of
     the Securities Act; and

          (B)  in the case of any Exchange Offer Registration Statement, the
     Company agrees to deliver, upon request, to the Trustee and to
     Participating Broker-Dealers who have delivered to the Company the notice
     referred to in Section 3(e) upon consummation of the Exchange Offer (i) an
     opinion of counsel substantially in the form attached hereto as Exhibit A,
     and (ii) an officers' certificate containing certifications substantially
     similar to those set forth in Section 5(c) of the Purchase Agreement.

          The Company may require each seller of Registrable Securities as to
which any registration is being effected to furnish to the Company such
information regarding such seller and the proposed distribution of such
Registrable Securities, as the Company may from time to time reasonably request
in writing. The Company may exclude from such registration the Registrable
Securities of any seller who fails to furnish such 
<PAGE>
 
                                     -23-

information within a reasonable time (not to exceed 10 Business Days) after
receiving such request and shall be under no obligation to compensate any such
seller for any lost income, interest or other opportunity forgone, or any
liability incurred, as a result of the Company's decision to exclude such
seller.

          In the case of (1) a Shelf Registration Statement or (2) Participating
Broker-Dealers who have notified the Company that they will be utilizing the
Prospectus contained in the Exchange Offer Registration Statement as provided in
Section 3(s) hereof, that are seeking to sell Exchange Securities and are
required to deliver Prospectuses, each Holder agrees that, upon receipt of any
notice from the Company of the happening of any event of the kind described in
Section 3(e)(ii), 3(e)(iii), 3(e)(iv), 3(e)(v) or 3(e)(vi) hereof, such Holder
will forthwith discontinue disposition of Registrable Securities pursuant to a
Registration Statement until such Holder's receipt of the copies of the
supplemented or amended Prospectus contemplated by Section 3(i) hereof or until
it is advised in writing (the "Advice") by the Company that the use of the 
                               ------         
applicable Prospectus may be resumed, and, if so directed by the Company, such
Holder will deliver to the Company (at the Company's expense) all copies in such
Holder's possession, other than permanent file copies then in such Holder's
possession, of the Prospectus covering such Registrable Securities or Exchange
Securities, as the case may be, current at the time of receipt of such notice.
If the Company shall give any such notice to suspend the disposition of
Registrable Securities or Exchange Securities, as the case may be, pursuant to a
Registration Statement, the Company shall use its best efforts to file and have
declared effective (if an amendment) as soon as practicable an amendment or
supplement to the Registration Statement and, in the case of an amendment, have
such amendment declared effective as soon as practicable and shall extend the
period during which such Registration Statement shall be maintained effective
pursuant to this Agreement by the number of days in the period from and
including the date of the giving of such notice to and including the date when
the Company shall have made available to the Holders (x) copies of the
supplemented or amended Prospectus necessary to resume such dispositions or (y)
the Advice.

          4.   Indemnification and Contribution.  (a)  The Company shall 
               --------------------------------                         
indemnify and hold harmless each Initial Purchaser, each Holder, each
Participating Broker-Dealer, each underwriter who participates in an offering of
Registrable Securities, their respective affiliates, each Person, if any, who
controls any of 
<PAGE>
 
                                     -24-

such parties within the meaning of Section 15 of the Securities Act or Section
20 of the Exchange Act, as follows:

          (i)  against any and all loss, liability, claim, damage and expense
     whatsoever, joint or several, as incurred, arising out of any untrue
     statement or alleged untrue statement of a material fact contained in any
     Registration Statement (or any amendment or supplement thereto), covering
     Registrable Securities or Exchange Securities, including all documents
     incorporated therein by reference, or the omission or alleged omission
     therefrom of a material fact required to be stated therein or necessary to
     make the statements therein not misleading or arising out of any untrue
     statement or alleged untrue statement of a material fact contained in any
     Prospectus (or any amendment or supplement thereto) or the omission or
     alleged omission therefrom of a material fact necessary in order to make
     the statements therein, in the light of the circumstances under which they
     were made, not misleading;

         (ii)  against any and all loss, liability, claim, damage and expense
     whatsoever, joint or several, as incurred, to the extent of the aggregate
     amount paid in settlement of any litigation, or any investigation or
     proceeding by any court or governmental agency or body, commenced or
     threatened, or of any claim whatsoever based upon any such untrue statement
     or omission, or any such alleged untrue statement or omission; provided
     that (subject to Sections 4(c) and 4(d) below) any such settlement is
     effected with the prior written consent of the Company; and

        (iii)  against any and all expenses whatsoever, as incurred (including
     reasonable fees and disbursements of one counsel chosen as provided in
     Section 4(c) below) reasonably incurred in investigating, preparing or
     defending against any litigation, or any investigation or proceeding by any
     court or governmental agency or body, commenced or threatened, or any claim
     whatsoever based upon any such untrue statement or omission, or any such
     alleged untrue statement or omission, to the extent that any such expense
     is not paid under subparagraph (i) or (ii) of this Section 4(a);

provided, however, that this indemnity does not apply to any loss, liability,
claim, damage or expense to the extent arising out of an untrue statement or
omission or alleged untrue statement or omission (i) made in reliance upon and
in conformity with written information furnished in writing to the Company by 
<PAGE>
 
                                     -25-

or on behalf of such Initial Purchaser, such Holder, such Participating Broker-
Dealer or any underwriter with respect to such Initial Purchaser, Holder,
Participating Broker-Dealer or underwriter, as the case may be, expressly for
use in the Registration Statement (or any amendment or supplement thereto) or
any Prospectus (or any amendment or supplement thereto) or (ii) contained in any
preliminary Prospectus or the final Prospectus if such Initial Purchaser, such
Holder, such Participating Broker-Dealer or such underwriter failed to send or
deliver a copy of the final Prospectus (or any amendment or supplement thereto)
to the Person asserting such losses, claims, damages or liabilities on or prior
to the delivery of written confirmation of any sale of securities covered
thereby to such Person in any case where the Company shall have previously
furnished copies thereof to such Initial Purchaser, such Holder, such
Participating Broker-Dealer or such underwriter, as the case may be, in
accordance with this Agreement, at or prior to the written confirmation of the
sale of such Securities to such Person and the untrue statement contained in or
the omission from the preliminary Prospectus or the final Prospectus was
corrected in the final Prospectus (or any amendment or supplement thereto). Any
amounts advanced by the Company to an indemnified party pursuant to this Section
4 as a result of such losses shall be returned to the Company if it shall be
finally determined by a court of competent jurisdiction in a judgment not
subject to appeal or final review that such indemnified party was not entitled
to indemnification by the Company.

          (b)  Each Holder agrees, severally and not jointly, to indemnify and
hold harmless the Company, each of its officers who signs any Registration
Statement, each Initial Purchaser, each underwriter who participates in an
offering of registrable Securities and the other selling Holders and each of
their respective directors and each Person, if any, who controls any of the
Company, the Initial Purchasers, any underwriter or any other selling Holder
within the meaning of Section 15 of the Act or Section 20 of the Exchange Act,
against any and all loss, liability, claim, damage and expense whatsoever
described in the indemnity contained in Section 4(a) hereof, as incurred, but
only with respect to untrue statements or omissions, or alleged untrue
statements or omissions, made in the Registration Statement (or any amendment or
supplement thereto) or any Prospectus (or any amendment or supplement thereto)
in reliance upon and in conformity with written information furnished to the
Company by or on behalf of such selling Holder with respect to such Holder
expressly for use in the Registration Statement (or any supplement thereto), or
any such Prospectus (or any amendment thereto); provided, however, that, 
<PAGE>
 
                                     -26-

in the case of the Shelf Registration Statement, no such Holder shall be liable
for any claims hereunder in excess of the amount of net proceeds received by
such Holder from the sale of Registrable Securities pursuant to the Shelf
Registration Statement.

          (c)  Each indemnified party shall give notice as promptly as
reasonably practicable to each indemnifying party of any action commenced
against it in respect of which indemnity may be sought hereunder, but failure to
so notify an indemnifying party shall not relieve such indemnifying party from
any liability hereunder to the extent it is not materially prejudiced as a
result thereof and in any event shall not relieve it from any liability which it
may have otherwise than on account of this indemnity agreement. In the case of
parties indemnified pursuant to Section 4(a) above, one counsel to all the
indemnified parties shall be selected by Merrill Lynch, and, in the case of
parties indemnified pursuant to Section 4(b) above, counsel to all the
indemnified parties shall be selected by the Company. An indemnifying party may
participate at its own expense in the defense of any such action; provided,
however, that counsel to the indemnifying party shall not (except with the
consent of the indemnified party) also be counsel to the indemnified party.
Notwithstanding the foregoing, if it so elects within a reasonable time after
receipt of such notice, an indemnifying party, jointly with any other
indemnifying parties receiving such notice, may assume the defense of such
action with counsel chosen by it and approved by the indemnified parties
defendant in such action (which approval shall not be unreasonably withheld),
unless such indemnified parties reasonably object to such assumption on the
ground that there may be legal defenses available to them which are different
from or in addition to those available to such indemnifying party. If an
indemnifying party assumes the defense of such action, the indemnifying parties
shall not be liable for any fees and expenses of counsel for the indemnified
parties incurred thereafter in connection with such action. In no event shall
the indemnifying parties be liable for fees and expenses of more than one
counsel (in addition to any local counsel) separate from their own counsel for
all indemnified parties in connection with any one action or separate but
similar or related actions arising out of the same general allegations or
circumstances. No indemnifying party shall, without the prior written consent of
the indemnified parties, settle or compromise or consent to the entry of any
judgment with respect to any litigation, or any investigation or proceeding by
any governmental agency or body, commenced or threatened, or any claim
whatsoever in respect of which indemnification or contri-
<PAGE>
 
                                     -27-

bution is sought under this Section 4, unless such settlement, compromise or
consent (i) includes a full and unconditional release of each indemnified party
from all liability arising out of such litigation, investigation, proceeding or
claim and the offer and sale of any Securities and (ii) does not include a
statement as to or an admission of fault, culpability or a failure to act by or
on behalf of any indemnified party.

          (d)  If at any time an indemnified party shall have requested an
indemnifying party to reimburse the indemnified party for reasonable fees and
expenses of counsel pursuant to Section 4(a)(iii) above, then such indemnifying
party agrees that it shall liable for any settlement of the nature contemplated
by Section 4(a)(ii) effected without its written consent if (i) such settlement
is entered into more than 45 days after receipt by such indemnifying party of
the aforesaid request, (ii) such indemnifying party shall have received notice
of the terms of such settlement at least 30 days prior to such settlement being
entered into and (iii) such indemnifying party shall not have reimbursed such
indemnified party in accordance with such request prior to the date of such
settlement.

          (e)  In order to provide for just and equitable contribution in
circumstances under which any of the indemnity provisions set forth in this
Section 4 is for any reason held to be unavailable to the indemnified parties
although applicable in accordance with its terms, the Company, the Initial
Purchasers and the Holders, as applicable, shall contribute to the aggregate
losses, liabilities, claims, damages and expenses of the nature contemplated by
such indemnity agreement incurred by the Company, the Initial Purchasers and the
Holders; provided, however, that no Person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any Person that was not guilty of such
fraudulent misrepresentation. As between the Company and the Initial Purchasers
and the Holders, such parties shall contribute to such aggregate losses,
liabilities, claims, damages and expenses of the nature contemplated by such
indemnity agreement in such proportion as shall be appropriate to reflect the
relative fault of the Company, on the one hand, and of the Holder of Registrable
Securities, the Participating Broker-Dealer or Initial Purchasers, as the case
may be, on the other hand, in connection with the statements or omissions which
resulted in such losses, liabilities, claims, damages or expenses, as well as
any other relevant equitable considerations.
<PAGE>
 
                                     -28-

          The relative fault of the Company, on the one hand, and the Holder of
Registrable Securities, the Participating Broker-Dealer or the Initial
Purchasers, as the case may be, on the other hand, shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company, or by the Holder of Registrable
Securities, the Participating Broker-Dealer or the Initial Purchasers, as the
case may be, and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission.

          The Company and the Holders of the Registrable Securities and the
Initial Purchasers agree that it would not be just and equitable if contribution
pursuant to this Section 4 were determined by pro rata allocation or by any
other method of allocation which does not take account of the equitable
considerations referred to above in this Section 4.

          For purposes of this Section 4, each affiliate of any Person, if any,
who controls a Holder of Registrable Securities, a Initial Purchaser or a
Participating Broker-Dealer within the meaning of Section 15 of the Securities
Act or Section 20 of the Exchange Act shall have the same rights to contribution
as such other Person, and each director of the Company, each affiliate of the
Company, each executive officer of the Company who signed the Registration
Statement, and each Person, if any, who controls any Issuer within the meaning
of Section 15 of the Securities act or Section 20 of the Exchange Act shall have
the same rights to contribution as the Company.

          5.   Participation in Underwritten Registrations.  No Holder may
               -------------------------------------------                
participate in any underwritten registration hereunder unless such Holder (a)
agrees to sell such Holder's Registrable Securities on the basis provided in any
underwriting arrangements approved by the Persons entitled hereunder to approve
such arrangements and (b) completes and executes all reasonable questionnaires,
powers of attorney, indemnities, underwriting agreements and other documents
reasonably required under the terms of such underwriting arrangements.  The
Company shall be under no obligation to compensate any Holder for lost income,
interest or other opportunity foregone, or other liability incurred, as a result
of the Company's decision to exclude such Holder from any underwritten
registration if such Holder has not complied with the provisions of this Section
5 in all material respects following 10 business days' written 
<PAGE>
 
                                     -29-

notice of non-compliance and the Company's decision to exclude such Holder.

          6.   Selection of Underwriters.  The Holders of Registrable Securities
               -------------------------                                        
covered by the Shelf Registration Statement who desire to do so may sell the
securities covered by such Shelf Registration in an underwritten offering. In
any such underwritten offering, the underwriter or underwriters and manager or
managers that will administer the offering will be selected by the Holders of a
majority in aggregate principal amount of the Registrable Securities covered by
the Shelf Registration Statement; provided, however, that such underwriters and
managers must be reasonably satisfactory to the Company.

          7.   Miscellaneous.
               ------------- 

          (a)  Rule 144 and Rule 144A.  So long as any of the Registrable
               ----------------------                                    
Securities are outstanding, the Company will file with the Commission, to the
extent then permitted by the Commission, the annual reports, quarterly reports
and other documents that the Company would have been required to file with the
Commission pursuant to Sections 13(a) and 15(d) of the Exchange Act if the
Company was subject to such Sections, and the Company will promptly provide to
the Trustee copies of such reports and documents; provided, however, that if the
Company is for any reason unable to make such filings it will make available,
upon request, to any Holder of Registrable Securities or prospective purchaser
of Registrable Securities the information specified in Rule 144A(d)(4) of the
Securities Act.

          (b)  No Inconsistent Agreements.  The rights granted to the Holders
               --------------------------                                    
hereunder do not, and will not for the term of this Agreement in any way
conflict with and are not, and will not during the term of this Agreement be
inconsistent with the rights granted to the holders of the Company's other
issued and outstanding securities under any other agreements entered into by the
Company.

          (c)  Amendments and Waivers.  The provisions of this Agreement,
               ----------------------                                    
including provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given, otherwise than with the prior written consent of the Company
and the Majority Holders; provided, however, that no amendment, modification, or
supplement or waiver or consent to the departure with respect to the provisions
of Section 4 hereof shall be effective as against any Holder of Registrable
Securities or any 
<PAGE>
 
                                     -30-

the Company unless consented to in writing by such Holder of Registrable
Securities or the Company, as the case may be.

          (d)  Notices.  All notices and other communications provided for or
               -------                                                       
permitted hereunder shall be made in writing by hand-delivery, registered first-
class mail, facsimile, or any courier guaranteeing overnight delivery (i) if to
a Holder, at the most current address given by such Holder to the Company by
means of a notice given in accordance with the provisions of this Section 7(d),
which address initially is, with respect to the Initial Purchasers, the address
set forth in the Purchase Agreement; and (ii) if to the Company, initially at
the Company's address set forth in the Purchase Agreement and thereafter at such
other address, notice of which is given in accordance with the provisions of
this Section 7(d).

          All such notices and communications shall be deemed to have been duly
given: at the time delivered by hand, if personally delivered; five Business
Days after being deposited in the mail, postage prepaid, if mailed; when receipt
is confirmed, if sent by facsimile; and on the next Business Day, if timely
delivered to an air courier guaranteeing overnight delivery.

          Copies of all such notices, demands, or other communications shall be
concurrently delivered by the Person giving the same to the Trustee, at the
address specified in the Indenture.

          (e)  Successors and Assigns.  This Agreement shall inure to the 
               ----------------------         
benefit of and be binding upon the successors, assigns and transferees of the
Initial Purchasers, including, without limitation and without the need for an
express assignment, subsequent Holders; provided, however, that nothing herein
shall be deemed to permit any assignment, transfer or other disposition of
Registrable Securities in violation of the terms of the Purchase Agreement or
the Indenture. If any transferee of any Holder shall acquire Registrable
Securities, in any manner, whether by operation of law or otherwise, such
Registrable Securities shall be held subject to all of the terms of this
Agreement, and by taking and holding such Registrable Securities, such Person
shall be conclusively deemed to have agreed to be bound by and to perform all of
the terms and provisions of this Agreement and such Person shall be entitled to
receive the benefits hereof.

          (f)  Third Party Beneficiary.  Each of the Initial Purchasers and each
               -----------------------                                          
Holder shall be a third party beneficiary

of the agreements made hereunder between the Company, on the one hand, and the
Initial Purchasers, on the other hand, and shall have the right to enforce such
agreements directly to the extent it deems such enforcement necessary or
advisable to protect its rights or the rights of Holders hereunder.

          (g)  Counterparts.  This Agreement may be executed in any number of
               ------------                                                  
counterparts and by the parties hereto in separate counterparts, each of which
when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.

other financial and statistical information and supplemental schedules included
or referred to therein or omitted therefrom and the Form T-1, as to which such
counsel need express no opinion), complies as to form in all material respects

ARTICLE II.  THE LOANS.

     2.01(A)  Subject to the terms and conditions of this Agreement, the Bank
will make a revolving credit facility (the "Revolving Credit Loan Commitment")
in an aggregate amount not to exceed $40,000,000 available to the Borrower,
pursuant to which the Bank may from time to time: (i) make revolving credit
advances, (ii) issue Letters of Credit to the Borrower or, (iii) make revolving
credit advances (a "DMC Revolving Credit Loan") to the Subsidiary Borrowers
(each a "Revolving Credit Loan").  The amount otherwise available for borrowing
under the Revolving Credit Loan Commitment shall be reduced by: (i)  the
aggregate face amounts of all Letters of Credit issued by Bank for the account
of Borrower and outstanding or drawn but unreimbursed from time to time, which
shall in no event exceed $20,000,000 at any time, (ii) the amount of DMC
Revolving Credit Loans outstanding which in no event shall exceed $5,000,000 at
any time, (iii) the amount of Debt of FarmPro, Inc. guaranteed by Borrower and
(iv) the amount of 

                                      12
<PAGE>
 
Revolving Credit Loans outstanding. All borrowings outstanding on the date
hereof, under the revolving credit facility made available pursuant to the
Original Loan Agreement, shall remain outstanding as Revolving Credit Loans
hereunder. The Revolving Credit Loan Commitment shall terminate on October 31,
2000 (the "Revolving Credit Loan Termination Date").

     (B) The Borrower may, from time to time, request whether for its own
account or for the Subsidiary Borrowers, by giving notice to the Bank prior to
11:00 a.m., that Revolving Credit Loans be made in an aggregate amount
specified, in a form specified (cash disbursement or continuation of outstanding
Loan) and on the Business Day specified in such request (which as to Euro-Dollar
Loans must also be a Euro-Dollar Business Day).  Prime Rate Loans may be
disbursed on the date requested.  If the Borrower elects whether for its own
account or for the Subsidiary Borrowers to pay interest on any Revolving Credit
Loan based on a Euro-Dollar Rate, notice must be given to the Bank at least
three Euro-Dollar Business days prior to the requested disbursement date.  Any
such notice must also specify the Interest Period selected by the Borrower for
each Loan based on a Euro-Dollar Rate and each request for a Euro-Dollar Loan
and Interest Period with respect thereto shall be irrevocable once given.  Not
later than 1:00 p.m., Chicago time, on the date specified in such request, the
Bank shall make the Revolving Credit Loan(s) to the Borrower or to the
Subsidiary Borrowers in the aggregate amount specified in such request, or
convert or continue the outstanding Loan, as the case may be.

     (C) The proceeds of Revolving Credit Loans shall be disbursed by deposit to
the Borrower's account maintained at the Bank or otherwise in accordance with
the written instructions of the Borrower or the other provisions of this
Agreement.  Revolving Credit Loans shall be used by the Borrower solely for its
working capital purposes, Letters of Credit for the Borrower or for the
Subsidiary Borrowers working capital purposes.  Bank may from time to time issue
one or more Letters of Credit at the request and for the account of the
Borrower, provided: (i) the aggregate amount of Letters of Credit outstanding
including those being requested plus amounts drawn under Letters of Credit but
not repaid to the Bank plus the principal sum of advances of Revolving Credit
Loans outstanding does not exceed $40,000,000; (ii) Borrower pays to Bank its
then internally published Letter of Credit issuance fee; (iii) the Borrower
executes and delivers to the Bank the Bank's then current form of Letter of
Credit Application or Agreement, in form and content satisfactory to the Bank,
including without limitation a LaSalle L/C Connection Agreement; (iv) the Bank
is not restricted or prohibited from issuing such Letter of Credit by any Law,
regulation or policy of any Governmental Authority or by Bank policy, and (v)
the aggregate amount of Letters of Credit outstanding including those being
requested plus amounts drawn under Letter of Credit but not repaid to the Bank
does not exceed $20,000,000.  Borrower's Obligations under this Agreement shall
include reimbursement obligations regarding Letters of Credit ("Letter of Credit
Obligations") and shall be secured by the Collateral in accordance with Article
IV below and any other collateral pledged to secure such Obligations pursuant to
any of the Documents.

     Borrower agrees to reimburse Bank on demand for each payment made by Bank
under or pursuant to any Letter of Credit or any draft drawn on Bank pursuant to
a Letter of Credit.  Bank 

                                      13
<PAGE>
 
may, in its sole discretion, provide for such reimbursement by advancing the
amount thereof to Borrower as a Revolving Credit Loan. In the event Bank does
not, in accordance with the terms and conditions hereof, make a Revolving Credit
Loan, for reimbursement, Borrower agrees to reimburse Bank in the amount of such
payment and shall also pay to Bank, on demand, interest at the rate provided in
Section 2.02(B) hereof on any amount paid by Bank under or pursuant to any
Letter of Credit or any draft drawn on Bank pursuant to a Letter of Credit from
the date of payment until the date of reimbursement to the Bank.

     Notwithstanding anything to the contrary herein or in any Letter of Credit
application of Borrower or other Document, upon the occurrence of an Event of
Default, an amount equal to the aggregate amount of the outstanding Letters of
Credit and all drawn but unreimbursed Letters of Credit shall, at Bank's option
and without demand upon or further notice to Borrower, be deemed (as between
Bank and Borrower) to have been paid or disbursed by Bank under the Letters of
Credit (notwithstanding that such amounts may not in fact have been so paid or
disbursed), and a Revolving Credit Loan to Borrower in the amount of such Letter
of Credit Obligations to have been made and accepted, which Revolving Credit
Loan shall be immediately due and payable.  In lieu of the foregoing, at the
election of Bank at any time after an Event of Default, Borrow shall, upon
Bank's demand, deliver to Bank cash, or other collateral of a type satisfactory
to Bank, having a value, as determined by Bank in its reasonable judgment, equal
to the aggregate Letter of Credit Obligations.  Any such collateral and/or any
amounts received by Bank in payment of the Revolving Credit Loan made pursuant
to this subparagraph shall be held by Bank in a separate account appropriately
designated as a cash collateral account in relation to this Agreement and the
Letters of Credit and retained by Bank as collateral security for Borrower's
Obligations in respect of this Agreement and each of the Letters of Credit.
Such amounts shall not be used by Bank to pay any amounts drawn or paid under or
pursuant to any Letter of Credit, but may be applied to reimburse Bank for
drawings or payments under or pursuant to any Letter of Credit which Bank has
paid, or if no such reimbursement is required, any cash collateral account
established pursuant to this subparagraph following payment in full of all of
the Obligations, which are not (as determined by Bank) to be applied to
reimburse Bank for amounts actually paid by Bank in respect of Letter of Credit,
shall be returned to Borrower (after deduction of Bank's reasonable expenses).

     This Agreement and any Letter of Credit application or other Document
regarding Letters of Credit shall be interpreted as supplemental to each other.
However, in the event of an express conflict in terms, the terms of this
Agreement shall govern.

     No Letter of Credit shall (i) be issued after the Revolving Credit Loan
Termination Date and (ii) have an expiration date later than the Revolving
Credit Loan Termination Date.

     Notwithstanding the above, the parties acknowledge that (i) Bank will, upon
the Borrower's request, issue for the account of Borrower Letters of Credit
having terms which expire after the expiration of the Revolving Credit Loan
Termination Date ("Post-Term L/Cs"), (ii) all security interests granted by
Borrower to Bank under this Agreement secure (inter alia) Letter of Credit
Obligations in respect of all Post-Term L/Cs, Bank agrees that upon payment and

                                      14
<PAGE>
 
satisfaction in full of all Obligations of Borrower in respect of the Revolving
Credit Loans, at a time when (1) no Event of Default and no event which, with
the giving of notice, the lapse of time, or both, would constitute an Event of
Default, exists, (2) all funding obligations of Bank to Borrower have been
terminated, and (3) Borrower has no Obligations to Bank other than those in
respect of Post-Term L/Cs, Bank will upon request of Borrower release the
security interests granted by Borrower in this Agreement, provided that Bank
receives replacement cash collateral in an amount, covering such Letter of
Credit Obligations, and pursuant to such documents, as Bank shall deem necessary
in its sole discretion, (iii) no Post-Term L/Cs shall have a term which expires
more than three years after the expiration of the Revolving Credit Loan
Termination Date, and (iv) the aggregate face amounts of the Post-Term L/Cs
shall not exceed $6,000,000.00.

     (D) All outstanding Revolving Credit Loans together with any accrued but
unpaid interest thereon shall be repaid in full on the Revolving Credit Loan
Termination Date.  In addition, outstanding Revolving Credit Loans shall be
repaid immediately, without the necessity of any demand or notice from Bank, if
and to the extent that they exceed the limitations imposed by Section 2.02(A)
above.  Borrower may repay and reborrow under the Revolving Credit Loan
Commitment subject to the terms and conditions of this Agreement.

     (E) The Revolving Credit Loans shall be evidenced by a note in the form of
Exhibit A hereto (the "Revolving Credit Note") and DMC Revolving Credit Loans
shall be evidenced by a note in the form of Exhibit B hereto (the "DMC Revolving
Credit Note").

     2.02(A)  Except as provided in Section 2.02(B) below, while any Revolving
Credit Loan is a Euro-Dollar Loan, it shall bear interest at a per-annum rate
equal to the applicable Euro-Dollar Rate, and at other times it shall bear
interest at the applicable Floating Rate.  Interest shall be calculated on the
basis of a 360-day year, counting the actual number of days elapsed.  Interest
on the Prime Rate Loans shall be paid monthly in arrears commencing on November
1, 1997 and continuing on the first day of each month thereafter.  Interest on
each Euro-Dollar Loan shall be paid on the applicable Payment Date; provided,
however, that if an Interest Period has a term of greater than 90 days, accrued
interest shall be payable on each 90-day anniversary of the first day of such
Interest Period, as well as on the Payment Date.

     (B) Any Obligation of the Borrower or the Subsidiary Borrowers which is not
paid when due, whether at stated maturity, by acceleration or otherwise, shall
bear interest payable on demand at the interest rate then in effect with respect
thereto plus two percent.  In addition, after the occurrence of any Event of
Default and delivery to the Borrower of the Bank's notice to charge post-default
interest, all Obligations of the Borrower and the Subsidiary Borrowers shall
bear interest at the highest rate provided for in the immediately preceding
sentence.

     (C) In the event the Borrower or the Subsidiary Borrowers elect to pay
interest on any Revolving Credit Loan based on a Euro-Dollar Rate, upon the
expiry of the applicable Interest Period, such Revolving Credit Loan shall bear
interest at the applicable rate determined by reference to the Prime Rate unless
the Borrower or the Subsidiary Borrowers repays such

                                      15
<PAGE>
 
Revolving Credit Loan on the Payment Date or the Borrower or the
Subsidiary Borrower timely elects, in the manner provided herein, to pay
interest based on a Euro-Dollar Rate prior to such expiry.

     (D) Notwithstanding any other provisions of this Agreement, if at any time
the Bank shall determine in good faith that any change in applicable law or
regulation or in the interpretation thereof makes it unlawful or unduly
burdensome for the Bank to make or continue to maintain any Euro-Dollar Loan,
then the Bank shall promptly give notice thereof to the Borrower, and the Bank's
obligation to make, continue or effect by conversion such Euro-Dollar Loan under
this Agreement shall terminate until it is no longer unlawful or unduly
burdensome for the Bank to make such Euro-Dollar Loan.  In such event, the
Borrower and the Subsidiary Borrowers shall prepay on demand the outstanding
principal amount of the affected Euro-Dollar Loans, together with all interest
accrued thereon and all other amounts payable to the Bank under this Agreement;
provided, however, the Borrower and the Subsidiary Borrowers may then elect to
borrow the principal amount of such Euro-Dollar Loans by means of a Prime Rate
Loan subject to the terms and conditions of this Agreement.

     (E) Notwithstanding any other provision of this Agreement to the contrary,
if prior to the commencement of any Interest Period the Bank shall determine (i)
that deposits in the amount of any Euro-Dollar Loan scheduled to be outstanding
are not available to the Bank in the relevant market or (ii) by reason of
circumstances affecting the relevant market, adequate and reasonable means do
not exist for ascertaining the Adjusted LIBOR Rate, then the Bank shall promptly
give notice thereof to the Borrower and the obligation of the Bank to make or
effect by conversion any such Euro-Dollar Loan in such amount and for such
Interest Period shall terminate until deposits in such amount and for the
Interest Period selected by the Borrower shall again be readily available in the
relevant market and adequate and reasonable means exist for ascertaining the
Adjusted LIBOR Rate.  Upon the giving of such notice, the Borrower and the
Subsidiary Borrowers may elect to either (i) pay or prepay, as the case may be,
such affected Loan together with all accrued interest thereon and all other
amounts payable to the Bank under Paragraph 2.02(H) of this Agreement or (ii)
convert such affected Revolving Credit Loan to a Prime Rate Loan, subject to all
the terms and conditions of this Agreement.

     (F) With respect to the Euro-Dollar Loans, if the Bank shall determine in
good faith that any change in any applicable law, treaty, regulation or
guideline (including, without limitation, Regulation D of the Board of Governors
of the Federal Reserve System) or any new law, treaty, regulation or guideline,
or any interpretation of any of the foregoing by any governmental authority
charged with the administration thereof or any central bank or other fiscal,
monetary or other authority having jurisdiction over the Bank or its Euro-Dollar
Lending Office or the Euro-Dollar Loans contemplated by this Agreement (whether
or not having the force of law) shall:

     (i)  impose, modify or deem applicable any reserve (but excluding with
          respect to any Euro-Dollar Loan any reserve percentage included in
          determining the applicable 

                                      16
<PAGE>
 
          Adjusted LIBOR Rate), capital, special deposit, compulsory loan,
          assessment or similar requirements against assets held by, or deposits
          in or for the account of, or loans by, or any other acquisition of
          funds or disbursements by, the Bank or an office thereof;

     (ii) subject the Bank, any Euro-Dollar Loan or the Note evidencing such
          Euro-Dollar Loans to any tax (including, without limitation, any
          United States interest equalization tax or similar tax however named
          applicable to the acquisition or holding of debt obligations and any
          interest or penalties with respect thereto), duty, charge, stamp tax,
          fee, deduction or withholding in respect of this Agreement, any Euro-
          Dollar Loan or any Note evidencing a Euro-Dollar Loan, except such
          taxes as may be measured by the overall net income of the Bank or its
          Euro-Dollar Lending Office and imposed by the jurisdiction, or any
          political subdivision or taxing authority thereof, in which the Bank's
          principal executive office or its Euro-Dollar Lending Office is
          located;

    (iii) change the basis of taxation of payments of principal and interest
          due from the Borrower to the Bank hereunder or under any Note
          evidencing a Euro-Dollar Loan (other than by a change in taxation of
          the overall net income of the Bank); or

     (iv) impose on the Bank any penalty with respect to the foregoing or any
          other condition regarding this Agreement, its disbursement, any Euro-
          Dollar Loan or any Note evidencing a Euro-Dollar Loan except for any
          penalty which results directly from the negligence or misconduct of
          the Bank in requesting such reimbursement;

and the Bank shall determine that the result of any of the foregoing is to
increase the cost (whether by incurring a cost or adding to a cost) to the Bank
of making or maintaining any Euro-Dollar Loan hereunder or to reduce the amount
of principal or interest received by the Bank (without benefit of, or credit
for, any prorations, exemptions, credits or other offsets available under any
such laws, treaties, regulations, guidelines or interpretations thereof), then
the Borrower and the Subsidiary Borrowers shall pay to the Bank on demand, from
time to time as specified by the Bank, such additional amounts as the Bank shall
determine are sufficient to compensate and indemnify the Bank for such increased
cost or reduced amount; provided that the Bank shall give prior notice of such
increased cost or reduced amount and the Borrower and the Subsidiary Borrowers
may at their option, prepay such affected Euro-Dollar Loans together with the
amount payable pursuant to Paragraph 2.03(H) hereof.  If Bank makes such a claim
for compensation, it shall provide to the Borrower a certificate setting forth
such increased cost or reduced amount and the basis for such determination as a
result of any event mentioned herein and such certificate shall in the absence
of manifest error, constitute prima facie evidence as to the amount thereof.

     (G) If prior to any Interest Period the Bank shall have determined (which
determination shall be conclusive and binding upon the Borrower and the
Subsidiary Borrowers) that the method of computing the rate of interest
applicable to any Euro-Dollar Loan does not accurately reflect 

                                      17
<PAGE>
     
the cost to the Bank of making or effecting by conversion any such Euro-Dollar
Loan, then the Bank shall give prompt telephonic, telex or telegraphic notice of
such determination to the Borrower. After such notice and in the event the
Borrower or the Subsidiary Borrowers desire to make or effect by conversion such
Euro-Dollar Loan, during the 30 calendar days next succeeding the giving of such
notice, the Borrower and the Bank shall negotiate in good faith in order to
arrive at a mutually satisfactory method of computing the interest rate
applicable to the Euro-Dollar Loans hereunder, as the case may be, to be
substituted for the interest rate specified in this Agreement. If within such 30
day period the Borrower and the Bank shall agree in writing upon a substituted
interest rate, then such substituted interest rate shall be effective from the
first day of the relevant Interest Period for such Euro-Dollar Loan. If the
Borrower and the Bank are unable to agree in writing upon a substituted rate
within the above thirty (30) day period, then the Borrower and the Subsidiary
Borrowers shall on demand either (i) prepay, without penalty or charge, the
relevant Euro-Dollar Loans, in full, or (ii) convert such Euro-Dollar Loans into
Prime Rate Loans subject to all the terms and conditions of this Agreement, and,
in either case, shall pay interest thereon from the date such Euro-Dollar Loan
was made or effected by conversion until such Euro-Dollar Loan is prepaid or
converted, as the case may be, at the rate per annum (rounded upward, if
necessary, to the nearest whole multiple of 1/16 of 1%) which is equal to the
sum of (i) 3.5% and (ii) the effective cost as computed by the Bank of
maintaining such Revolving Credit Loan from deposits obtained in the secondary
market, together with all other amounts then due and payable to the Bank under
this Agreement. A certificate as to such effective cost and the manner of the
computation of such cost shall, in the absence of manifest error, constitute
prima facie evidence as to the amount thereof.

     (H)   In the event the Bank shall incur any loss, cost or expense
(including, without limitation, any loss of profit and any loss, cost or expense
incurred by reason of the liquidation or re-employment of deposits or other
funds acquired by the Bank to fund or maintain any Euro-Dollar Loan or the
relending or reinvesting of such deposits or amounts paid or prepaid to the
Bank) as a result of:

     (i)   any payment (including, without limitation, any prepayment) of a 
           Euro-Dollar Loan on a date other than the last day of the then 
           applicable Interest Period;

     (ii)  any failure by the Borrower or the Subsidiary Borrowers to borrow a
           Euro-Dollar Loan on the date specified in its notice given pursuant
           to this Agreement;

     (iii) any failure by the Borrower or the Subsidiary Borrowers to make any
           payment of principal or interest when due on any Euro-Dollar Loan,
           whether at stated maturity, by acceleration or otherwise; or

     (iv)  the occurrence of any Event of Default;

then, upon the demand of the Bank, the Borrower and the Subsidiary Borrowers
shall pay to the Bank such amount as will reimburse the Bank for such loss, cost
or expense to the extent such 

                                      18
<PAGE>
 
loss, cost or expense is not otherwise reimbursed by the after-maturity interest
rate specified in this Agreement or reimbursed pursuant to Section 9.03 hereof.
If Bank makes such a claim for compensation, it shall provide to the Borrower a
certificate setting forth the amount of such loss, cost or expense in reasonable
detail and the manner of computation of the same and such certificate shall
constitute, in the absence of manifest error, prima facie evidence as to the
amount thereof.

     (I)  The Bank may, at its option, elect to make, fund or maintain its Loans
hereunder at the branch or office specified on the signature page hereto or such
other of its branches or offices as the Bank may from time to time elect.

     (J)  Notwithstanding any provision of this Agreement to the contrary, the
Bank shall be entitled to fund and maintain its funding of all or any part of
the Loans in any manner it sees fit, it being understood, however, that for the
purposes of this Agreement all determinations hereunder as to Euro-Dollar Loans
shall be made as if the Bank had actually funded and maintained each Euro-Dollar
Loan during each Interest Period for such Euro-Dollar Loan through the purchase
of deposits in the relevant market having a maturity corresponding to such
Interest Period and bearing an interest rate equal to the Euro-Dollar Rate for
such Interest Period.

     (K)  The provisions of Section 2.02(H) hereof shall survive for a period of
six months following the later of the termination of this Agreement and the
payment in full of the Revolving Credit Loans.

     (L)  The Bank agrees that in making calculations and determinations under
Sections 2.02(F), (G) and (H) above, it will do so in good faith and will make
allocations, on an equitable basis, of amounts to be charged to Borrower and to
other customers of the Bank which have arrangements for LIBOR borrowings similar
to those hereunder.

     2.04  If, at any time, the interest rate and other charges imposed
hereunder shall be deemed by any competent Governmental Authority to exceed the
maximum rate of interest permitted by any applicable Laws, for such time as the
interest and such charges would be deemed excessive, its application shall be
suspended and there shall be charged instead the maximum rate of interest and
charges permissible under such Laws.

     2.05  All payments, which are not prepayments, received from the Borrower
or the Subsidiary Borrowers for payment on the Revolving Credit Loans shall be
applied by the Bank first to unpaid interest due and payable on the Revolving
Credit Loan, then to the reduction of the principal outstanding on the Revolving
Credit Loans.

     2.06  (A)  At Closing, the Borrower shall pay to Bank a non-refundable
closing fee in the amount of $100,000.00, which fee shall be fully earned at the
time of Closing.

                                      19
<PAGE>
    
          (B) The Borrower shall pay to Bank a fee (the "Facility Fee") equal to
the Applicable Margin per annum times $40,000,000.00. Such fee shall be payable
quarterly in arrears on the first day of each September, December, March and
June hereafter.

     2.07 All payments received from the Borrower hereunder shall be paid
directly to the Bank without setoff or counterclaim in immediately available
funds. The Bank shall send the Borrower statements of all amounts due hereunder,
which statements shall be considered correct and conclusively binding on the
Borrower absent manifest error.

provisions of Sections 4.02 and 4.03 is herein collectively called the
"Collateral."  The Collateral, together with all of the Borrower's other
property of any kind held by the Bank, shall stand as one general, continuing

Borrower, the Borrower hereby assigns, transfers and sets over to the Bank all
of its right, title and interest in and to, and grants the Bank a lien on and a
security interest in, all amounts that may be owing from time to time by the
Bank to the Borrower in any capacity, including, but without limitation, any
balance or share belonging to the Borrower of any deposit or other account with
the Bank, which lien and security interest shall be independent of any right of
set-off which the Bank may have.

     4.03 As further security for the prompt satisfaction of all Obligations of
the Borrower, the Borrower hereby assigns, transfers and sets over to the Bank
all of its right, title and interest in and to, and grants to the Bank a lien on

<PAGE>
 
In addition and as further security, the Borrower will execute and deliver to
the Bank security agreements and such other documents, including financing
statements, in connection herewith as shall be required by the Bank.

     4.04  The liens created in Sections 4.02 and 4.03 shall be first and prior
liens, subject only to Permitted Liens.

     4.05  The Borrower represents and warrants to the Bank as follows:

     (A) The Borrower is the owner of the Collateral and grants the security
interest made in Sections 4.02 and 4.03 in consideration of value given by the
Bank, the sufficiency of which the Borrower hereby acknowledges.

     (B) Other than the security interests granted in Sections 4.02 and 4.03,
the Collateral is free from any lien, security interest, encumbrance or other
right, title or interest of any other Person except for Permitted Liens.

     (C) All Collateral is kept solely at the location or locations identified
in Schedule 2.  Except as specified on Schedule 2, no Collateral is or shall be
kept, stored or maintained with a bailee, warehouseman, carrier or similar party
without the Bank's prior written consent.

     (D) With respect to Accounts, except as otherwise disclosed by the Borrower
to the Bank in writing:

          (i)    the Accounts are genuine, in all respects what they purport to
                 be and are not evidenced by a judgment;

          (ii)   the Accounts represent bona fide transactions completed in
                 accordance with the terms and provisions contained in the
                 invoices and other documents evidencing same;

          (iii)  the amounts thereof, which are shown on all such invoices and
                 statements evidencing same, are actually and absolutely owing
                 to the Borrower and are not contingent for any reason;

          (iv)   to the best of the Borrower's knowledge, there are no setoffs,
                 counterclaims or disputes existing or asserted with respect to
                 the Accounts and the Borrower has not made any agreement with
                 any Account Debtor thereof for any deduction therefrom;

          (v)    to the best of the Borrower's knowledge, there are no facts,
                 events or occurrences which in any way impair the validity or
                 enforceability of the

                                      22
<PAGE>
 
                  Accounts or tend to reduce the amount payable thereunder from
                  the amount thereof;

          (vi)    to the best of the Borrower's knowledge, all of the Account
                  Debtors have the capacity to contract and are solvent;

          (vii)   the services and/or goods sold giving rise to the Accounts are
                  not subject to any lien, claim, encumbrance or security
                  interest except that of the Bank and except for Permitted
                  Liens;

          (viii)  the Borrower has no knowledge of any fact or circumstance
                  which would impair the validity or collectability of the
                  Accounts;

          (ix)    to the best of the Borrower's knowledge, there are no
                  proceedings or actions which are threatened or pending against
                  any Account Debtor which might result in a material adverse
                  change in such Account Debtor's financial condition; and

          (x)     none of the Accounts is pursuant to an invoice requiring
                  payment in more than 30 days, except for Accounts representing
                  in the aggregate not more than 5% of all Accounts.

     (E) With respect to Inventory, the Borrower has correct and accurate
records itemizing and describing the type and quantity of Inventory, and the
Borrower's cost therefor and selling price thereof; provided, however, that it
is acknowledged that Borrower does not maintain a perpetual inventory at its
manufacturing facility, but rather performs an annual physical inventory
thereat.

     4.06  Immediately upon the Borrower's receipt of that portion of the
Collateral, if any, which is evidenced by an instrument and/or document,
including promissory notes, documents of title, certificated securities and
warehouse receipts (collectively the "Special Collateral") for the purpose of
perfecting the Bank's security interest in such Special Collateral, the Borrower
shall deliver the original thereof to the Bank, together with appropriate
endorsements and/or specific evidence of the assignment thereof to the Bank, in
form and substance acceptable to the Bank; provided, however, that unless there
shall exist an Event of Default or Bank shall have specifically requested same,
Borrower need not deliver to Bank Special Collateral representing advances to
employees.

     4.07  If and to the extent that any of the Collateral is evidenced by, or
arises under, any contract with the United States of America or any agency or
instrumentality thereof, the Borrower will immediately notify the Bank of same.

     4.08  The Borrower covenants and agrees with the Bank as follows:

                                      23
<PAGE>
 
     (A) The Borrower will not hereafter grant a security interest in the
Collateral, or transfer the Collateral to any other Person, except as
specifically permitted by this Agreement.

     (B) The Borrower will at all times defend the Collateral against any and
all claims of any Person adverse to the claims of the Bank.

     (C) All of the Borrower's places of business, including the Borrower's
principal office, are described on Schedule 2.  All Collateral covered by this
Agreement is and will be kept only at location(s) specified on Schedule 2.
Collateral shall not be removed to, or kept at, and Borrower shall not establish
a place of business at, any other place without the prior written consent of the
Bank, other than new locations within the 48 contiguous states, provided that
(i) at least 60 days prior to the establishment of such new location, the
Borrower shall have given Bank written notice thereof, and (ii) prior to the
establishment of such new location, the Borrower shall have delivered to Bank
such financing statements, third-party lien waivers and other documentation as
Bank shall require in connection therewith.  If Collateral is at any time kept
or located at locations other than those listed, the Bank's security interest
therein shall continue.

     (D) During the preceding five years, neither the Borrower nor any
predecessor of the Borrower has been known as or used any corporate, fictitious
or trade names or trade styles, other than those disclosed on Schedule 3.

     (E) All patents, trademarks, service marks and copyrights, and all
licenses, registrations and applications for registration thereof, owned, used
or to be used by the Borrower in the operation of its business, are listed on
Schedule 4.  The Borrower will promptly notify the Bank in writing of the
Borrower's acquisition of any such assets hereafter occurring.

     (F) The Equipment in which Bank is granted a security interest will not at
any time be affixed or attached to any real estate in such a manner that it will
become a fixture, unless the Bank shall have a first priority, perfected lien on
such real estate as security for the Obligations of the Borrower.  The Equipment
will be used or bought for use solely for business purposes.

     (G) The Borrower shall permit the Bank to inspect and evaluate the
Collateral and any books and records of the Borrower relating thereto at all
reasonable times and to verify any Accounts by any reasonable method
satisfactory to the Bank, all at the expense and risk of the Borrower.

     (H) By identifying Accounts on any schedule or other document delivered to
Bank the Borrower shall be deemed to be making the representations and
warranties contained in Section 4.05(D) with respect to such Accounts.

     (I) With respect to Accounts, the Borrower shall:


                                      24
<PAGE>
 
          (i)  promptly upon the Borrower's learning thereof, inform the Bank in
               writing of any material delay in the Borrower's performance of
               any of its obligations to any Account Debtor whose outstanding
               Accounts aggregate $500,000.00 or more and of any assertion of
               any claims, offsets or counterclaims by any such Account Debtor
               and of any extraordinary allowances, credits and/or other monies
               granted by the Borrower to any such Account Debtor;

         (ii)  not permit or agree to any material extension, compromise or
               settlement or make any change or modification of any kind or
               nature with respect to any material Accounts, including any of
               the terms relating thereto; provided, however, Borrower may
               convert the Accounts of an Account Debtor identified to it in a
               side letter of even date herewith (the "Side Letter") to a note
               in an aggregate principal amount not to exceed $6,000,000.00 in
               accordance with terms described in the Side Letter;

        (iii)  promptly upon the Borrower's receipt or learning thereof,
               inform the Bank of the commencement of bankruptcy proceedings
               involving any Account Debtor whose outstanding Accounts aggregate
               $500,000.00 or more; and

         (iv)  other than goods returned in the ordinary course of business and
               having an aggregate invoice price not exceeding $500,000.00 per
               year, keep all goods returned by any Account Debtor and all goods
               repossessed or stopped in transit by the Borrower from any
               Account Debtor segregated from the other property of the
               Borrower, and hold the same as trustee for the Bank until resold
               or otherwise directed in writing by the Bank.

     (J) With respect to Inventory, the Borrower shall from and after the date
hereof keep correct and accurate records reflecting the Borrower's cost therefor
and the selling price thereof, all of which records shall be available at all
reasonable times, upon demand, to any of the Bank's officers, employees or agent
for inspection and copying thereof.

     (K) The Borrower shall keep and maintain the Equipment in good operating
condition and repair and shall make all necessary replacements thereof and
renewals thereto so that the value and operating efficiency thereof shall at all
times be maintained and preserved; provided, however, that the Borrower may sell
obsolete Equipment for a price which reasonably approximates its fair market
value if the proceeds thereof are paid directly to the Bank for application to
the Borrower's Obligations.

     4.09  The Borrower shall, at its sole cost and expense, keep and maintain
the Collateral insured for the greater of the full insurable value or the full
replacement value thereof against loss or damage by fire, theft, explosions,
sprinklers and all other hazards and risks (i) covered by extended coverage
and/or (ii) ordinarily insured against by other owners or users of properties in


                                      25
<PAGE>
 
similar businesses.  All such policies of insurance shall be in form, with
insurers and in such amounts as may be satisfactory to the Bank.  The Borrower
shall deliver to the Bank a certificate of insurance with respect to each policy
of insurance and evidence of payment of all premiums for each such policy.  Such
policies of insurance shall contain a lender's loss payable endorsement, in form
and substance acceptable to the Bank, showing loss payable to the Bank.  Such
endorsement or an independent instrument furnished to the Bank shall provide
that all insurance companies shall give the Bank at least thirty (30) days prior
written notice before any such policy or policies of insurance shall be altered
or cancelled and that no act or default of the Borrower or any other Person
shall affect the right of the Bank to recover under such policy or policies of
insurance in case of loss or damage.  The Borrower hereby directs all insurers
under such policies of insurance to pay all proceeds payable thereunder directly
to the Bank.  With respect to all claims in excess of $100,000.00, and with
respect to all claims of any size at any time during the existence of an Event
of Default, the Borrower irrevocably appoints the Bank and all officers,
employees or agents designated by the Bank as the Borrower's true and lawful
attorney and agent in fact for the purpose of making, settling and adjusting
claims under such policies of insurance, endorsing the name of the Borrower on
any check, draft, instrument or other item of payment for the proceeds of such
policies of insurance and for making all determinations and decisions with
respect to such policies of insurance.  If Borrower at any time or times
hereafter shall fail to obtain or maintain any of the policies of insurance
required above, or to pay any premium in whole or in part relating thereto, the
Bank, without waiving or releasing any of the Obligations of the Borrower or any
Event of Default, may at any time or times thereafter, but shall be under no
obligation to do so, obtain and maintain such policies of insurance and pay such
premiums and take any other action with respect thereto which the Bank deems
necessary or advisable.  All sums so disbursed by the Bank, including attorney's
fees, court costs, expenses and other charges relating thereto, shall be part of
the Obligations, payable by the Borrower to the Bank on demand.

     4.10  The Bank may, at any time or times hereafter, in its sole discretion,
without waiving or releasing any obligation, liability or duty of the Borrower
under this Agreement or the other Documents, or any Event of Default, pay,
acquire and/or accept an assignment of any security interest, lien, claim or
encumbrance asserted by any Person against the Collateral.  All sums paid by the
Bank in respect thereof and all costs, fees and expenses, including, without
limitation, attorneys' fees, court costs, expenses and other charges relating
thereto, which are incurred by the Bank on account thereof, shall be payable,
upon demand, by the Borrower to the Bank and shall be additional Obligations of
the Borrower hereunder secured by the Collateral.

     4.11  Simultaneous herewith, the Subsidiary Borrowers are delivering the
following:  (a) the DMC Revolving Credit Note, (b) a guaranty of the Obligations
of Borrower, and (c) security agreements pledging certain assets.

     4.12  Each of the representations, warranties and agreements set forth in
this Article IV shall survive the execution and delivery of this Agreement and
shall remain effective until this Agreement shall have been terminated and all
Obligations of the Borrower shall have been paid and satisfied in full.

ARTICLE V.  REPRESENTATIONS AND WARRANTIES
            ------------------------------

     To induce the Bank to consummate the transactions contemplated hereby, the
Borrower represents and warrants to the Bank as follows:

     5.01  The Borrower is a corporation duly organized, validly existing and in
good standing under the laws of the State of Delaware, has the lawful power and
authority to own its properties and to carry on its business as now conducted,
and is qualified to do business and is in good standing as a foreign corporation
in the State of Illinois and in each other jurisdiction wherein the nature of
the business transacted or to be transacted by it or property owned or to be
owned by it makes such qualification necessary and where the failure to be so
qualified would have a material adverse effect on its business, properties or
condition, financial or otherwise and possesses all material permits necessary
to operate the business it conducts.

     5.02  The Borrower is empowered to perform all acts and things undertaken
and done pursuant to this Agreement and has taken all corporate or other action
necessary to authorize the execution, delivery and performance of the Documents.
The officers of Borrower executing the Documents have been duly elected or
appointed and have been fully authorized to execute such Documents at the time
executed.  The Documents, when executed and delivered, will be the legal, valid
and binding obligations of the Borrower, enforceable against it in accordance
with their respective terms.

     5.03  The Financial Statements are complete and accurate, fairly present
the financial condition of the Borrower at the respective dates thereof and the
results of operations for the respective periods covered thereby, and (subject
to normal year-end adjustments with respect to interim Financial Statements)
were prepared in accordance with GAAP.  The Borrower does not have any material
liabilities or obligations (contingent or otherwise), liability for taxes or
unusual forward or long-term commitments, except as disclosed in the Financial
Statements, and except for obligations under Stockholder Agreements.

     5.04  Since the date of Borrower's most recent audited Financial
Statements, there has been no material change (except as described in the
Offering Memorandum) in the assets, liabilities or financial condition of
Borrower, other than changes arising from transactions in the ordinary course of
business and the financing transactions contemplated by this Agreement, and none
of such changes has been materially adverse.

     5.05  Other than as set forth in the Financial Statements, there are no
actions, suits or proceedings pending, or, to the best of the knowledge of the
Borrower, threatened against or affecting the Borrower at law or in equity or
before or by any Governmental Authority or any foreign equivalent thereof, which
involve the possibility of any material judgment or liability, or which are, in
the aggregate, material in light of the financial condition and assets of the
Borrower.  There are no actions, suits, investigations or proceedings pending,
or to the best of the knowledge 

                                      27
<PAGE>
 
of the Borrower, threatened against the Borrower or its properties regarding
Environmental Laws, the manufacture, storage or treatment of Hazardous
Substances or products liability.

     5.06  The Borrower is not in violation of, and the execution and delivery
of the Documents and the performance by the Borrower of its obligations under
the Documents, do not and will not result in the Borrower being in violation of
or in conflict with, or constitute a default under any of, the Borrower's
organizational documents, any term or provision of any note, mortgage,
indenture, contract, agreement, instrument, judgment or Law applicable to the
Borrower, or result in the creation or imposition of any mortgage, lien, charge
or encumbrance of any nature whatsoever (other than those in favor of Bank) upon
any of the assets of the Borrower pursuant to any such term or provision.  The
Borrower is not in default, after the expiration of any applicable grace or cure
periods, in any respect in the performance or fulfillment of any of its
obligations, covenants or conditions contained in any agreement or instrument to
which it is a party or by which any of its properties may be bound, and the
Borrower does not know of any dispute regarding any such agreement or
instrument.

     5.07  The Borrower's uses of the proceeds of the Loans are, and will
continue to be, legal and proper corporate uses which are consistent with all
applicable Laws, with Borrower's Certificate of Incorporation, its By-Laws, the
resolutions of its Board of Directors, and the terms of this Agreement.

     5.08  The Borrower does not have outstanding any Debt (except to Bank and
the Subordinated Notes,) or other obligation for borrowed money, or for the
deferred purchase price of property or services and the Borrower is not
obligated as guarantor, co-signer or otherwise on any Debt or other obligation
of any kind of any other Person, except and to the extent shown on the Financial
Statements at the date of this Agreement, incurred in the ordinary course of
business or pursuant to the Stockholder Agreements.  No Person is in default
under any of said obligations.

     5.09  All tax returns and reports of the Borrower required by law to be
filed, have been duly filed, and all taxes, assessments, fees and other
governmental charges (other than those presently payable without penalty or

and remedies provided by this Agreement or any other Document and by applicable
law and, without limiting the generality of the foregoing, may, at its option,
declare the Revolving Credit Loan Commitment to be terminated by giving written

convenient to both parties; collect any money due or to become due and enforce
in the Borrower's name all rights with respect to the Collateral; receive and
open mail addressed to the Borrower; and/or notify any Account Debtors (whether
or not such Account Debtors are in default) to make payments directly to the

in the form in which received (together with all necessary endorsements), all
payments received by the Borrower in respect of any Account. The Bank may apply
all such payments against the Borrower's Obligations or at the Bank's option to
any of the Borrower's accounts maintained at the Bank.

     9.03  In exercising its right to sell, lease or otherwise dispose of the
Collateral, the Bank may sell, lease or otherwise dispose of all or any
Collateral in its then condition, or after any further manufacturing or
processing thereof, at public or private sale or sales, with such notice as may
be required by law, in lots or in bulk, all as the Bank, in its sole discretion,
may deem advisable; such sales may be adjourned from time to time with or
without notice.  The Bank shall have the right to conduct such sales on the
Borrower's premises or elsewhere and shall have the right to use the Borrower's
premises without charge for such sales for such time or times as the Bank may
see fit.  The Bank is hereby granted a license or other right to use, without
charge, the Borrower's labels, patents, copyrights, rights of use of any name,
trade secrets, tradenames, trademarks, service marks and advertising matter, or
any property of a similar nature, as it pertains to the Collateral, in
advertising for sale and selling any Collateral and the Borrower's rights under
all licenses and all franchise agreements shall inure to the Bank's benefit.
The Bank shall have the right to sell, lease or otherwise dispose of the
Collateral, or any part thereof, for cash, credit or any combination thereof,
and the Bank may purchase all or any part of the Collateral at public or, if
permitted by law, private sale and, in lieu of actual payment of such purchase
price, may set off the amount of such price against the Borrower's Obligations.
The proceeds realized from the sale of any Collateral shall be applied first to
the costs, expenses and attorneys' fees and expenses incurred by the Bank for
collection and for acquisition, completion, protection, removal, storage, sale
and delivery of the Collateral; second to interest due upon any of the
Borrower's Obligations; and third to the principal of the Borrower's
Obligations.  If any deficiency shall arise, the Borrower shall remain liable to
the Bank therefor.

     9.04  Any notice of any sale, lease, other disposition, or other intended
action by the Bank shall be reasonable if it is given to the Borrower at least
ten (10) days in advance of the intended disposition or other intended action.

     9.05  Upon and after the occurrence of an Event of Default, the Borrower
irrevocably designates, makes, constitutes and appoints the Bank (and all
persons designated by the Bank) as the Borrower's true and lawful attorney, and
the Bank or its agent, may, without notice to the Borrower, and at such time or
times thereafter as the Bank or said agent, in its sole discretion, may
determine, in the Borrower's or the Bank's name:  (i) demand payment of the
Accounts; (ii) enforce payment of the Accounts, by legal proceedings or
otherwise; (iii) exercise all of the 

                                      40
<PAGE>
 
Borrower's rights and remedies with respect to the collection of the Accounts
and Special Collateral; (iv) settle, adjust, compromise, extend or renew the
Accounts; (v) settle, adjust or compromise any legal proceedings brought to
collect the Accounts or any other dispute with respect thereto; (vi) if
permitted by applicable law, sell or assign the Accounts and Special Collateral
upon such terms, for such amounts and at such time or times as the Bank deems
advisable; (vii) discharge and release the Accounts and Special Collateral;
(viii) prepare, file and sign the Borrower's name on a Proof of Claim in
Bankruptcy or similar document against any Account Debtor; (ix) prepare, file
and sign the Borrower's name on any notice of lien, assignment or satisfaction
of lien or similar document in connection with the Accounts and Special
Collateral; (x) do all acts and things necessary, in the Bank's sole discretion,
to fulfill the Borrower's obligations under this Agreement; (xi) endorse the
name of the Borrower upon any item of payment or proceeds and deposit the same
to the account of the Bank on account of the Borrower's Obligations; (xii)
endorse the name of the Borrower upon any chattel paper, document, instrument,
invoice, freight bill, bill of lading or similar document or agreement relating
to the Accounts, Inventory and Special Collateral; (xiii) use the Borrower's
stationery and sign the name of the Borrower to verifications of the Accounts
and notices thereof to Account Debtors; and (xiv) use the information recorded
on or contained in any data processing equipment and computer hardware and
software relating to the Accounts, Inventory and Special Collateral to which the
Borrower has access.

     9.06  The Borrower agrees that in any sale of Collateral consisting of
securities, the Bank is hereby authorized to comply with any limitation or
restriction in connection with such sale as Bank may be advised by counsel is
necessary or advisable in order to avoid any violation of applicable Law
(including, without limitation, compliance with such procedures as may restrict
the number of prospective bidders and purchasers, require that such prospective
bidders and purchasers have certain qualifications, and restrict such
prospective bidders and purchasers to Persons who will represent and agree that
they are purchasing for their own account for investment and not with a view to
the distribution or resale of that portion of the Collateral consisting of
securities), or in order to obtain any required approval of the sale or of the
purchaser by any governmental regulatory authority or official, and the Borrower
further agrees that such compliance shall not result in such sale being
considered commercially unreasonable, nor shall the Bank be liable or
accountable to the Borrower for any discount allowed by reason of the fact that
Collateral was sold in compliance with any such limitation or restriction.


ARTICLE X.  MISCELLANEOUS
            -------------

     10.01  No failure or delay on the part of the Bank in exercising any right,
power or remedy hereunder or under any other Documents shall operate as a waiver
thereof, nor shall any single or partial exercise of any such right, power or
remedy preclude any other or further exercise thereof or the exercise of any
other right, power or remedy hereunder or under any other Document.  The
remedies herein provided and under any other Document are cumulative and not
exclusive of any remedies provided by law.

                                      41
<PAGE>
 
     10.02  This Agreement and the other Documents constitute the entire
agreement between the parties and there are no promises expressed or implied
unless contained herein and therein. No amendment, modification, termination or
waiver of any provision of the Documents nor consent to any departure by the
Borrower therefrom shall in any event be effective unless the same shall be in
writing and signed by the Bank, and then such waiver or consent shall be
effective only for the specific purpose for which given, and shall not be deemed
a waiver of or consent to any other matter or to the same matter in a different
instance. No notice to or demand on the Borrower in any case shall entitle the
Borrower to any other or further notice or demand in similar or other
circumstances.

     10.03  The Borrower will pay any documentary, stamp or similar taxes
payable in respect of the Documents or the Collateral granted hereby or in
connection herewith. The Borrower will, on demand, reimburse the Bank for the
fees and expenses of legal counsel for the Bank incurred by the Bank in
connection with the preparation of the Documents, and the negotiation and
closing of the transactions contemplated hereby. The Borrower will further, on
demand, reimburse the Bank for all expenses, including the fees and expenses of
legal counsel for the Bank, incurred by the Bank in connection with any
amendment or modification of the Documents, the administration of the Loans and
the enforcement of the Documents and the collection or attempted collection of
the Obligations of the Borrower.

     10.04  (A)  For the purposes of any action or proceeding involving the
Documents or any other agreement or document referred to therein, the Borrower
hereby expressly submits to the jurisdiction of all federal and state courts
located in the State of Illinois and consents that any order, process, notice of
motion or other application to or by any of said courts or a judge thereof may
be served within or without such court's jurisdiction by registered mail or by
personal service, provided a reasonable time for appearance is allowed.  The
Borrower hereby irrevocably waives any objection that it may now or hereafter
have to the laying of venue of any suit, action or proceeding arising out of or
relating to this Agreement or any other Document brought in any federal or state
court sitting in Cook County, State of Illinois, and hereby further irrevocably
waives any claim that any such suit, action or proceeding brought in any such
court has been brought in an inconvenient forum.

     (B)  THE BORROWER HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVES
(TO THE EXTENT PERMITTED BY APPLICABLE LAW) ANY RIGHT IT MAY HAVE TO A TRIAL BY
JURY OF ANY DISPUTE ARISING UNDER OR RELATING TO THIS AGREEMENT, THE NOTES, ANY
OTHER OF THE DOCUMENTS OR ANY OTHER AGREEMENT OR DOCUMENT REFERRED TO HEREIN OR
THEREIN AND AGREES THAT ANY SUCH DISPUTE SHALL BE TRIED BEFORE A JUDGE SITTING
WITHOUT A JURY.

     10.05  The Borrower agrees to indemnify the Bank from and against any and
all liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements of any kind or nature whatsoever
(including, without limitation, fees and disbursements of

                                      42
<PAGE>
 
counsel) which may be imposed on, incurred by, or asserted against the Bank in
any litigation, proceeding or investigation instituted or conducted by any
governmental agency or instrumentality or any other Person with respect to any
aspect of, or any transaction contemplated by, or referred to in, or any matter
related to, this Agreement or the Stock Redemption Agreement, whether or not the
Bank is a party thereto, except to the extent that any of the foregoing arises
out of the gross negligence or wilful misconduct of the Bank.

     10.06  The Borrower acknowledges and agrees that this Agreement constitutes
a commitment on the part of the Bank to make advances, incur obligations and
otherwise to give value to the Borrower and that all financing statements filed
hereunder shall remain in full force and effect until this Agreement shall have
been terminated even if, at any time or times prior to such termination, no
Loans or other Obligations shall be outstanding hereunder. Accordingly, the
Borrower waives any rights which it may have under Section 9-404(1) of the UCC
to demand the filing of termination statements with respect to the Collateral,
and agrees that the Bank shall not be required to send such termination
statements to the Borrower, or to file them with any filing office, unless and
until this Agreement shall have been terminated and all Obligations of the
Borrower shall have been paid in full in immediately available funds.

otherwise) of the principal of and interest on the DMC Revolving Credit Note
issued by the Subsidiary Borrowers pursuant to this Agreement, and the full and
punctual payment of all other amounts payable by each of the Subsidiary

     (c)  any release, impairment, non-perfection or invalidity of any direct or
indirect security for any obligation of any Subsidiary Borrower under this
Agreement or any Document or the DMC Revolving Credit Note;

     (d)  any change in the corporate existence, structure or ownership of any
Subsidiary Borrower or any insolvency, bankruptcy, reorganization or other
similar proceeding affecting any Subsidiary Borrower or such Subsidiary
Borrower's assets or any resulting release or discharge of any obligation of any
Subsidiary Borrower contained in this Agreement or the DMC Revolving Credit
Note;

     (e)  the existence of any claim, set-off or other right which Borrower may

compulsory counterclaim;

     (f)  any invalidity or unenforceability relating to or against any
Subsidiary Borrower for any reason of this Agreement or the DMC Revolving Credit
Note, or any provision of applicable law or regulation purporting to prohibit
the payment by any Subsidiary Borrower of the principal of or interest on the
DMC Revolving Credit Note or any other amount payable by any Subsidiary Borrower
under this Agreement or the DMC Revolving Credit Note; or

     (g)  any other act or omission to act or delay of any kind by any
Subsidiary Borrower or any other person or any other circumstance whatsoever
which might, but for the provisions of this paragraph, constitute a legal or
equitable discharge of Borrower's obligations as guarantor hereunder.

     10.20  Borrower's obligations as guarantor hereunder shall remain in full
force and effect until the Revolving Credit Loan Commitment shall have
terminated and all Obligations of the Subsidiary Borrowers under this Agreement

payment of principal, interest or any other amount payable by any

                                      46
<PAGE>
 
Subsidiary Borrower under this Agreement or the DMC Revolving Credit Note is
rescinded or must be otherwise restored or returned upon the insolvency,
bankruptcy or reorganization of such Subsidiary Borrower or otherwise,
Borrower's obligations hereunder with respect to such payment shall be
reinstated as though such payment had been due but not made at such time.

     10.21  Borrower irrevocably waives acceptance hereof, presentment, demand,
protest and any notice not provided for herein, as well as any requirement that
at any time any action be taken by any Person against any Subsidiary Borrower or
any other Person.

Subsidiary Borrower pursuant to this Agreement, Borrower shall not be subrogated
to any right of the Bank until such time as the Bank shall have received final
payment in cash of the full amount of all Obligations.

     10.23  If acceleration of the time for payment of any amount payable by any
Subsidiary Borrower under this Agreement or the DMC Revolving Credit Note is
stayed upon the insolvency, bankruptcy or reorganization of such Subsidiary
Borrower, all such amounts otherwise subject to acceleration under the terms of
this Agreement shall nonetheless be payable by Borrower hereunder forthwith on
demand by the Bank.

                                    GUARANTY
                                    --------

          FOR VALUE RECEIVED, and in consideration of any loans, advances,
payments, extensions of credit and/or other financial accommodations heretofore,
now or hereafter made, granted or extended by Mercantile Bank National
Association, a national banking association, its successors and assigns
("Lender"), or which Lender has or will become obligated to make, grant or
extend, to or for the account of FarmPRO, Inc., a Pennsylvania corporation
("Borrower"), and in consideration of any obligations heretofore, now or
hereafter incurred by Borrower to Lender, the undersigned, The GSI Group, Inc.,
a Delaware corporation (the "Guarantor"), hereby absolutely and unconditionally
guarantees to Lender the prompt and complete payment when due in accordance with
their respective terms (whether by reason of demand, maturity, acceleration or
otherwise) of any and all of the present and future "Borrower's Obligations" (as
defined in that certain Loan Agreement dated the date hereof by and between
Borrower and Lender, as the same may from time to time be amended, modified,
extended or renewed (the "Loan Agreement")) (collectively, the "Guaranteed
Indebtedness"); provided, however, that the Guaranteed Indebtedness shall not
include (a) any portion of the Borrower's Obligations consisting of principal
(and not interest, fees or collection costs and expenses) (the "Principal
Portion of the Borrower's Obligations") which is incurred by Borrower after
November 26, 1998, or (b) the Principal Portion of the Borrower's Obligations
which is in excess of $6,000,000.00, if any. In addition, the Guarantor shall
and agrees to be liable to Lender for all costs and expenses incurred by Lender
in attempting or effecting collection hereunder (whether or not litigation shall
be commenced in aid thereof) and in connection with representation of Lender in
connection with bankruptcy or insolvency proceedings relating hereto, including,
without limitation, reasonable attorneys' fees and expenses.

          Notice of the acceptance of this Guaranty, and of the incurrence of 
any of the Guaranteed Indebtedness, and presentment, demand for payment, notice
of dishonor, protest, notice of protest and of default by Borrower are hereby
waived by the Guarantor who agrees: (i) that this Guaranty is a guaranty of
payment and not of collection and the obligations of the Guarantor hereunder may
be enforced directly against the Guarantor independently of and without
proceeding against Borrower or any other guarantor(s) of any or all of the
Guaranteed Indebtedness or foreclosing any collateral pledged to Lender; (ii)
that Lender in its sole and absolute discretion may from time to time extend the
time of payment, change the interest rates and renew or change the manner,
place, time and terms of payment of and make any other changes with respect to
any or all of the Guaranteed Indebtedness; (iii) that Lender may from time to
time in its sole and absolute discretion sell, exchange, release, surrender and
otherwise deal with any collateral pledged to Lender by Borrower or any other
person or entity to secure any or all of the Guaranteed Indebtedness; (iv) that
Lender may from time to time in its sole and absolute discretion release and
otherwise deal with any other guarantor(s) of any or all of the Guaranteed
Indebtedness; and (v) that Lender may from time to time exercise or refrain from
exercising any rights against Borrower or any other guarantor(s) of any or all
of the Guaranteed Indebtedness and otherwise act or refrain from acting with
respect to Borrower or any other guarantor(s) of any or all of the Guaranteed
Indebtedness, and may from time to time settle or compromise any or all of the
Guaranteed Indebtedness with Borrower; all without notice to or consent of the
Guarantor and without releasing the Guarantor.

          The Guarantor shall have no right of subrogation, reimbursement,
contribution or indemnity whatsoever with respect to Borrower or any other
guarantor(s) of any or all of the Guaranteed Indebtedness and no right of
recourse to or with respect to any assets or property of Borrower or any other
guarantor(s) of any or all of the Guaranteed Indebtedness or to any collateral
or other security 
<PAGE>
 
for the payment of any of the Guaranteed Indebtedness unless and until all of
the Guaranteed Indebtedness shall have been fully, finally and indefeasibly paid
in cash and all of the financing arrangements and commitments between Borrower
and Lender have been terminated. Nothing shall discharge or satisfy the
liability of the Guarantor under this Guaranty except the full performance and
payment of all of the Guaranteed Indebtedness and all obligations of the
Guarantor under this Guaranty.

          Lender's books and records showing the account between Lender and
Borrower shall be admissible in evidence in any action or proceeding and shall
constitute prima facie proof of the items therein set forth.

          No invalidity, irregularity or unenforceability of any or all of the
Guaranteed Indebtedness or of any collateral or any other guarantees therefor
shall affect, impair or be a defense to this Guaranty.  The liability of the
Guarantor under this Guaranty shall in no way be affected or impaired by any
acceptance by Lender of any collateral for or other guarantees of any of the
Guaranteed Indebtedness, or by any failure, neglect or omission on the part of
Lender to realize upon or protect any of the Guaranteed Indebtedness or any
collateral therefor or guarantees thereof.  No act of commission or omission of
any kind by Lender (including, without limitation, any act or omission which
impairs, reduces the value of, releases or fails to perfect a lien upon, any
collateral for or guarantee of any of the Guaranteed Indebtedness) shall affect
or impair the obligations or the Guarantor under this Guaranty in any manner.

          If claim is ever made on Lender for repayment or recovery of any
amount or amounts received by Lender in payment or on account of any of the
Guaranteed Indebtedness (including payment under a guaranty or from application
of collateral) and Lender repays all or part of said amount by reason of (a) any
judgment, decree or order of any court or administrative body having
jurisdiction over Lender or any of Lender's property or (b) any settlement or
compromise of any such claim effected by Lender with any such claimant
(including, without limitation, Borrower), then and in such event the Guarantor
agrees that any such judgment, decree, order, settlement or compromise shall be
binding on the Guarantor, notwithstanding any cancellation of any note or other
instrument or agreement evidencing such Guaranteed Indebtedness or of this
Guaranty, and the Guarantor shall be and remain liable to Lender hereunder for
the amount so repaid or recovered to the same extent as if such amount had never
originally been received by Lender. This Guaranty shall continue to be effective
or be reinstated, as the case may be, if (i) at any time any payment of any of
the Guaranteed Indebtedness is rescinded or must otherwise be returned by Lender
upon the insolvency, bankruptcy or reorganization of Borrower or otherwise, all
as though such payment had not been made or (ii) this Guaranty is released or
the liability of the Guarantor hereunder is reduced in consideration of a
payment of money or transfer of property or grant of a security interest by the
Guarantor or any other person or entity and such payment, transfer or grant is
rescinded or must otherwise be returned by Lender upon the insolvency,
bankruptcy or reorganization of such person or entity or otherwise, all as
though such payment, transfer or grant had not been made.
 
          The Guarantor hereby represents and warrants to Lender that (a) the
Guarantor is a corporation duly organized, validly existing and in good standing
under the laws of the State of Delaware, (b) the execution, delivery and
performance by the Guarantor of this Guaranty (i) are within the corporate
powers of the Guarantor, (ii) have been duly authorized by all necessary
corporate action on the part of the Guarantor, (iii) require no action by or in
respect of, consent or approval of or filing or recording with, any governmental
or regulatory body, agency 

                                      -2-
<PAGE>
 
or official or any other third party and (iv) do not conflict with, or result in
a breach of the terms, conditions or provisions of, or constitute a default
under or result in any violation of, the terms of the Certificate or Articles of
Incorporation or Bylaws of the Guarantor, any applicable law, rule, regulation,
order, writ, judgment or decree of any court or governmental or regulatory
agency or instrumentality or any agreement, document or instrument to which the
Guarantor is a party or by which it is bound or to which it is subject and (c)
this Guaranty constitutes the legal, valid and binding obligation of the
Guarantor and is enforceable against the Guarantor in accordance with its terms,
except as such enforceability may be limited by (i) applicable bankruptcy,
insolvency or similar laws affecting the enforcement of creditors' rights
generally and (ii) general principles of equity (regardless of whether such
enforceability is considered in a proceeding in equity or at law).

          No delay by Lender in exercising any of its options, powers or rights
or partial or single exercise thereof shall constitute a waiver thereof. No
waiver of any of Lender's rights hereunder and no modification or amendment of
this Guaranty shall be deemed to be made by Lender unless the same shall be in
writing, duly signed on Lender's behalf, and each such waiver (if any) shall
apply only with respect to the specific instance involved and shall in no way
impair Lender's rights or the obligations of the Guarantor to Lender in any
other respect at any other time. In the event any one or more of the provisions
contained in this Guaranty should be invalid, illegal or enforceable in any
respect, the validity, legality and enforceability of the remaining provisions
of this Guaranty shall not be affected or impaired thereby.

          All payments made under or pursuant  to this Guaranty may be allocated
among the principal, interest and other portions of the Guaranteed Indebtedness
and the other obligations of the Guarantor hereunder in such order as Lender may
determine in its sole and absolute discretion.

          The Guarantor hereby covenants and agrees to deliver to Lender such
financial statements and other financial information regarding the Guarantor as
Lender may from time to time reasonably request.

          This Guaranty is a continuing guaranty which shall remain in full
force and effect and shall not be terminable so long as either (i) any
Guaranteed Indebtedness shall remain in force and effect or (ii) Lender shall
have any commitment or obligation to make loans, extend credit or grant other
financial accommodations to Borrower. The dissolution of the Guarantor shall not
effect a termination of this Guaranty.

          This Guaranty shall be understood to be for the benefit of Lender and
for such other person or persons as may from time to time become or be the
holder or owner of such other person or persons as may from time to time become
or be the holder or owner of any of the Guaranteed Indebtedness or any interest
therein and this Guaranty shall be transferable to the same extent and with the
same force and effect as any of the Guaranteed Indebtedness may be transferable.
This Guaranty cannot be changed or terminated orally, shall be governed by and
construed in accordance with the substantive laws of the State of Missouri
(without reference to conflict of law principles), shall be binding on the
successors and assigns of the Guarantor and shall inure to the benefit of
Lender's successors and assigns.

          THE GUARANTOR HEREBY IRREVOCABLY (A) SUBMITS TO THE NONEXCLUSIVE
JURISDICTION OF ANY MISSOURI STATE COURT OR ANY UNITED STATES OF AMERICA COURT
SITTING IN THE EASTERN DISTRICT OF MISSOURI, EASTER DIVISION, AS LENDER MAY
ELECT,

(B) AGREES THAT ALL CLAIMS IN RESPECT TO ANY SUCH SUIT, ACTION OR PROCEEDING MAY
BE HELD AND DETERMINED IN ANY OF SUCH COURTS, (C) WAIVES, TO THE FULLEST EXTENT
PERMITTED BY LAW, ANY OBJECTION WHICH THE GUARANTOR MAY NOW OR HEREAFTER HAVE TO
THE LAYING OF VENUE OF ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN ANY SUCH
COURT, (D) WAIVES ANY CLAIM THAT SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN ANY
SUCH COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM AND (E) WAIVES ALL RIGHTS
OF ANY OTHER JURISDICTION WHICH THE GUARANTOR MAY NOW OR HEREAFTER HAVE BY
REASON OF ITS PRESENT OR SUBSEQUENT DOMICILES. THE GUARANTOR (AND BY ITS
ACCEPTANCE HEREOF, LENDER) IRREVOCABLY WAIVE THE RIGHT TO TRIAL BY JURY WITH
RESPECT TO ANY ACTION IN WHICH THE GUARANTOR AND LENDER ARE PARTIES RELATING TO
OR ARISING OUT OF OR IN CONNECTION WITH THIS GUARANTY.

(hereinafter referred to as the "Premises").

     2.  Term. The term of this lease shall be one (1) year, beginning on the

terminate. The Lease shall terminate upon purchase of the Premises by Tenant
pursuant to paragraph 19.

     3.  Rental. The Tenant shall pay a total rental of Fifty-Seven Thousand Six
Hundred Dollars ($57,600.00) for the initial one (1) year term, payable in equal
monthly installments of Four Thousand Eight Hundred Dollars ($4,800.00) each, in
advance, to Richard Perry on the first day of each month commencing on April 1,
1997, which is the effective date of this lease.

     4.  Renewal Term Rent. During each extended term, the basic rent shall be
Sixty Three Thousand Three Hundred and Sixty Dollars ($63,360.00) or Five

     5.  General Taxes. The Landlord shall pay all general real estate taxes on
the Premises and shall, upon request by Tenant, furnish Tenant with paid
receipts, cancelled checks or other proof of payment satisfactory to Tenant.
Tenant shall reimburse Landlord for the amount of real estate tax paid in excess
of those paid for the tax year 1995, which reimbursement will be paid with the
October rent of each year starting October, 1998.

     6.  Insurance. The Landlord shall keep the Premises insured throughout the
term and any extended term of this lease, protecting both the Landlord and the
Tenant against loss or damages by fire, lightning, earthquake, windstorm or
other casualty ordinarily covered by extended coverage in an amount not less
than $565,000.00, and claims for personal injury and property damage under a
policy of general public liability insurance with limits as may be reasonably
requested by the Tenant from time to time, but not less than $1,000,000 per
person and $3,000,000 per occurrence, in a company or companies acceptable to
the Tenant. The Landlord shall deliver to the Tenant a certificate of insurance
showing compliance with this
<PAGE>
 
                                      -3-

provision and naming Tenant as an additional insured. Tenant shall maintain a
policy of general public liability insurance with limits not less than
$1,000,000 per person and $3,000,000 per occurrence, in a company or companies
acceptable to Landlord. The Tenant shall also maintain property insurance on its
property located on the Premises. The Tenant shall deliver to the Landlord a
certificate of insurance showing compliance with this provision and naming
Landlord as an additional insured.

     7.  Use. The Tenant shall have the right to use the Premises for any lawful
business, including, without limitation, a light manufacturing location;
provided, however, the Tenant agrees that it will not sell or permit the sale of
any alcoholic beverages in the Premises.

     8.  Quiet Enjoyment. The Tenant, upon paying the basic rent and all
additional rent and other charges herein provided for, and performing all of the
other terms of this lease, shall quietly have and enjoy the Premises during the
term of this lease without hindrance or molestation by anyone claiming by or
through the Landlord, subject, however, to the reservations and conditions of
this lease.

     9.  Maintenance, Repair, Janitor Service and Other Expenses. The Tenant
shall, at its own expense, make all necessary repairs and replacements to the
Premises and to the pipes, heating and air conditioning systems, alarm system,
plumbing system, window glass, fixtures, and all other appliances and
appurtenances belonging thereto, and all equipment used in connection with the
Premises, except the roof which shall be repaired at Landlord's expense. All
repairs shall be promptly made with materials of like quality to the original
work. On default of the Tenant in making needed repairs, the Landlord may, but
shall not be required to, make such repairs for the Tenant's account and the
expense thereof shall constitute and be
<PAGE>
 
                                      -4-

collectible as additional rent. The Tenant shall provide janitor service for the
Premises and Tenant shall also pay for the removal of certain interior walls if
Tenant removes them.

     10.  Surrender of Premises.  At the expiration of the lease term, the
Tenant shall surrender the Premises in as good condition as it was in at the
beginning of the term, reasonable use and wear and damage by fire or other
casualty without the fault or negligence of Tenant excepted.

     11.  Improvements by Tenant.  No alterations, additions, or improvements to
the Premises shall be made by the Tenant without the written consent of the
Landlord, which consent shall not be unreasonably withheld or delayed. Any
alteration, addition, or improvement made by the Tenant after such consent shall
have been given, shall be done so without causing a lien to be attached to the
Premises and, at the Landlord's option, become the property of the Landlord upon
the expiration or other sooner termination of this lease; provided, however,
that the Landlord shall have the right to require the Tenant to remove such
fixtures at the Tenant's expense upon such termination of this lease.

     12.  Landlord's Representations and Warranties.  Landlord represents and
warrants that: the Premises are in good order and repair, provided that the
Tenant shall accept the electrical, heating, plumbing and air conditioning
systems in their present condition without representation or warranty; the
Premises are not subject to any zoning or other governmental use restrictions;
Landlord is the owner of the Premises and that the Premises are free and clear
of all mortgages, liens and encumbrances except the lien of real estate taxes
not yet due and payable and easements of record and a mortgage in favor of
Security Bank & Trust of Mt. Carmel, Illinois; to the best of Landlord's
knowledge, neither Landlord nor any predecessor in
<PAGE>
 
                                      -5-

interest to Landlord has released or deposited upon the Premises any Hazardous
Materials (as defined elsewhere in this section); to the best of Landlord's
knowledge, neither Landlord nor any predecessor in interest to Landlord has
received notice of the existence or alleged existence of any Hazardous Materials
upon or under the Premises from any governmental agency or other party; and
there is one underground fuel oil tank on the Premises.

     Hazardous Materials, as used herein, shall include, without limitation,
petroleum and petroleum products, those substances defined as hazardous
substances in the Comprehensive Environmental Response Compensation and
Liability Act of 1980, as amended ("CERCLA"), and those wastes defined as
hazardous wastes under the Resource Conservation and Recovery Act, as amended
("RCRA"), and any other substance identified as being hazardous, toxic or
dangerous under any local, Illinois or federal environmental law or regulation.

     13.  Utilities and Other Services.  The Tenant shall pay all expense of
heat, air conditioning, electricity, water and all other services furnished the
Premises throughout the lease term.

     14.  Access.  The Landlord shall have full and unrestricted access to the
Premises for any reasonable purpose during normal business hours throughout the
lease term.

     15.  Fire or Other Casualty Loss.  In case of damage by fire or other
casualty to the Premises, without fault or negligence of the Tenant, if the
damage is so extensive as to amount practically to the total destruction of the
Premises, this lease shall terminate, and the rent shall be apportioned to the
time of the damage. In all other cases where the Premises is damaged by fire or
other casualty without the fault or negligence of the Tenant, the Landlord shall
repair the
<PAGE>
 
                                      -6-

damage with reasonable dispatch, and if the damage has rendered the Premises
untenantable, in whole or in part, there shall be an apportionment of the rent
until the damage has been repaired.

     16.  Condemnation.  If the Premises or any part thereof is taken by eminent
domain, or conveyed upon threat of such proceedings, this lease shall expire on
the date when the Premises shall be so taken or conveyed, and the rent shall be
apportioned as of that date. No part of any award shall belong to the Tenant
other than that portion attributable to leasehold improvements made by Tenant
and that portion attributable to cost of or removal of Tenant's stock, equipment
and fixtures.

     17.  Sign.  Tenant shall be allowed to place signs identifying the Premises
in windows of the Premises or on or attached to the building.

     18.  Assignment of Lease.  Neither party shall assign this lease or sublet
the Premises without the prior written consent of the other, which consent shall
not be unreasonably withheld or delayed.

     19.  Indemnification.  Tenant shall indemnify the Landlord against any
accident, injury, death or damage to any person or property which shall happen
in or about the Premises during the term of the Lease, unless due to an act or
omission of Landlord.

     20.  Option to Purchase.  Tenant shall have the option to purchase the
Premises for Four Hundred Eighty Thousand Dollars ($480,000.00) at any time
during the initial term or extended term of this Lease, and, if such option is
exercised in the first two years, such purchase price shall be reduced by 1/3 of
all first year lease payments and 1/4 of all second year lease payments made by
Buyer under this Lease. To exercise its option, Tenant shall execute and deliver
the Real Estate Purchase Agreement, a copy of which is attached hereto.

                         LEASE WITH OPTION TO PURCHASE
                         -----------------------------


     This Lease with Option to Purchase entered into in Paris, Illinois, this
12th day of July, 1996, by and between Edgar County Bank & Trust Company as
Trustee for Trust No. 455-232, under Trust Agreement dated August 24, 1988 and
Chris Patrick of Paris, Illinois, the beneficiary of such trust (Trustee and Mr.
Patrick are hereinafter collectively referred to as the "Lessor"), and The GSI
Group, Inc., a Delaware corporation, of Assumption, Illinois ("Lessee").

     1.   Lessor hereby leases to the Lessee, and the Lessee hereby leases from
the Lessor, approximately 6 acres located approximately five (5) miles north of
Paris, Illinois at Rural Route 6, Box 175 together with the existing building
and improvements located thereon, containing approximately 36,000 square feet,
and all other appurtenances, rights, privileges and easements thereto belonging
and, hereinafter referred to as the "premises".  A legal description of the
premises is attached hereto as Exhibit A.

     2.   The initial term of this Lease is twelve (12) months, commencing on
the date hereof.  Lessee shall have the option to extend the term of this Lease
for up to an additional twelve (12) months after the expiration of the initial
term by providing Lessor with written notice of its intent to exercise such
option at least thirty (30) days prior to expiration of the initial term.  Upon
expiration or earlier termination of this Lease, unless Lessee has exercised its
purchase option, Lessee will surrender the premises in as good order and
condition as when received, reasonable wear and tear, alterations permitted by
Lessor, damage from the elements, fire, acts of God, or other casualty excepted.

     3.   Lessee agrees to use and occupy the premises for the purpose of
storing property related to its business and conducting a manufacturing
business, or any other uses associated therewith.  Lessee shall not, at any
time, use the premises for manufacturing, storing or selling intoxicating liquor
(including, without limitation, beer and wine).  Lessee agrees to keep the
premises in a clean and orderly condition and to arrange and pay for the
removal, on a regular basis, of all trash, garbage, and similar items generated
by Lessee.

<PAGE>
    
     4.   Lessee agrees to pay to Lessor as rent for the premises the sum of Two
Thousand, Five Hundred Dollars ($2,500.00) per month, payable in advance on the
lst day of each and every month of the term, the first such payment being due on
the date of the commencement of the Lease under paragraph 2, and each succeeding
payment to be made on or before the first day of each succeeding calendar month.
Rent for any part of a calendar month shall be prorated in the proportion which
the number of days Lessee has possession of the premises in such month bears to
the total number of days in said month.  Each late installment of rent shall
bear interest at the rate of twelve percent (12%) per year from the date due
until paid if not actually received by Lessor within five (5) days of the due
date.

     5.   Lessee agrees to pay as additional rent hereunder:

          a.   Real estate taxes and assessments, ordinary and extraordinary,
               general and specific, which may be levied or assessed on, or with
               respect to, the premises, prorated for the term of this Lease.
               Lessee's portion of these taxes shall be paid to Lessor on or
               before the due date or the due date of the last rent payment,
               whichever first occurs, or if the Lease is earlier terminated
               without breach by Lessee and without exercise of Lessee's
               purchase option, the Lessee's tax obligation shall be calculated
               to the date of, and be paid on, such termination;

          b.   All fuel, power, water, electricity, and any other utilities over
               the term of the Lease;

          c.   Maintenance and repair of the interior of the buildings and all
               mechanical, electrical and compressed air systems and equipment
               maintenance (including, without limitation, all heating and
               ventilating equipment and plumbing), glass and fixtures; and

          d.   The cost of any improvements or modifications to the premises
               made by Lessee as provided by paragraph 12.

     6.   All expenses of maintenance of the structure and the exterior of the
buildings and improvements located on the premises, including all glass in
exterior doors and windows, shall be paid by the Lessee; provided that Lessor
will pay for the repair of all major roof problems.  Any damage to the building
on the premises caused by Lessee shall be repaired and paid for by Lessee.  Any
structural condition requiring repair that is not covered by the insurance
required to be provided by Lessee pursuant to paragraph 8 shall be paid for by
Lessor unless such condition is caused by Lessee and provided neither 

                                       2
<PAGE>
 
Lessee nor Lessor shall be required to replace the roof. If any such structural
condition is reasonably estimated to cost more than $50,000 to repair and Lessor
determines that it is not in its interest to undertake such repairs, either
party hereto will have the option for a period of thirty (30) days after Lessor
communicates such determination to Lessee to terminate this Lease.

     7.   Lessor represents and warrants that:

          a.   the premises are in good order and repair;

          b.   the premises are not subject to any zoning or other governmental
               use restrictions;

          c.   it is the owner of the premises and that the premises are free
               and clear of all mortgages, liens and encumbrances except the
               lien of real estate taxes not yet due and payable, easements of
               record and a collateral assignment of beneficial interest in the
               aforementioned trust;

          d.   neither Lessor nor, to the best of Lessor's knowledge, any
               predecessor in interest to Lessor has released or deposited upon
               the premises any hazardous materials except as may be disclosed
               in the Phase II Environmental Assessment dated May 3, 1996 by
               Andrews Environmental Engineering Inc. (the "Audit");

          e.   neither Lessor nor, to the best of Lessor's knowledge, any
               predecessor in interest to Lessor, has received notice of the
               existence or alleged existence of any hazardous materials upon or
               under the premises from any governmental agency or other party
               except as disclosed in the Audit; and

          f.   there are no underground storage tanks on the premises.

As used in this Lease, the term "hazardous materials" shall include, but not be
limited to, substances defined as "hazardous substances", "hazardous materials"
or "toxic substances" in the Comprehensive Environmental Response, Compensation
and Liability Act of 1980, as amended, 42 U.S.C. Sec. 9601, et seq.; the
Hazardous Materials Transportation Act, 49 U.S.C. 1801 et seq.; the Resources
Conservation and Recovery Act, 42 U.S.C. Sec. 6901 et seq.; the Toxic Substances
Control Act, 15 U.S.C. Sec. 2601 et seq.; the Clean Air Act, 42 U.S.C. Sec. 7401
et seq.; and the Clean Water Act, 33 U.S.C. Sec. 1251 et seq. (collectively, the
"Environmental Laws"), but, for purposes of this paragraph, only if such
substances, if found on the premises, are in violation of any such act or a
governmental rule or regulation.

                                       3
<PAGE>
 
     Lessor covenants and warrants that Lessee, if not in default, shall
peacefully and quietly hold and enjoy the premises during the term hereof.
Lessor agrees not to allow any liens or encumbrances having priority over the
Lease to be placed upon the premises during the term hereof and to promptly
cause any such lien to be removed should it exist in the future.

     Notwithstanding any other provision contained herein, Lessor covenants and
agrees that it shall be obligated to remediate the groundwater contamination
disclosed in the Audit (the "Pre-Exiting Condition") by July 11, 1997; provided,
however, that if Lessor determines that the cost of such remediation (based upon
a reasonable contractor's estimate) will exceed $30,000, Lessor will deliver a
copy of such estimate to Lessee and, if such estimate is satisfactory to Lessee,
either party hereto will have the right for a period of thirty (30) days to
terminate this Lease. If such estimate is unsatisfactory to Lessee, Lessee will
have the right to obtain its own estimate and the average of the two will be
deemed to be the cost of remediation for the purposes of the immediately
preceding sentence. If Lessor fails to remediate the Pre-Existing Condition by
July 11, 1997, Lessor shall be deemed to have breached such covenant and Lessee
shall have the right to take the actions provided under either paragraph 15(a)
or 15(b) immediately. Lessor shall indemnify and hold harmless Lessee from any
liability, cost or expense of any nature whatsoever relating to, resulting from
or arising out of the Pre-Existing Condition or the remediation thereof. For
purposes of this Lease, the remediation of the Pre-Existing Condition shall be
considered complete when, after full disclosure and investigation, the Illinois
Environmental Protection Agency issues a "No Further Remediation" letter to
Lessor specifically addressing the Pre-Existing Condition.

     8.   During the term of this Lease and all extensions thereof, Lessee will
keep the premises insured by a responsible insurance company or companies
licensed in Illinois against loss or damage by fire, lightning, tornado,
earthquake, windstorm and other casualty ordinarily covered by extended coverage
in an amount not less than $1 million.  Within thirty (30) days after the date
hereof, Lessee shall provide Lessor with a certificate evidencing such
insurance, naming Lessor as an additional insured.

                                       4
<PAGE>
 
     9.   Lessor shall not be liable to Lessee or any other person for injury or
death to persons or damage to property on the premises from Lessee's failure to
keep the premises in repair or from the act, omission, or negligence of any
person other than Lessor, its employees, agents and invitees.  Lessee will
indemnify Lessor for, and hold Lessor harmless from, all claims for injury or
death to persons or damage of any kind to property arising out of Lessee's use
or occupancy of the premises.

     10.  Lessee will permit Lessor and its agents to enter on the premises or
any part thereof, with 48 hours written notice during normal business hours,
for the purpose of examining the same or making such repairs or alterations as
may be necessary for the safety or preservation thereof.

     11.  Lessee agrees not to assign this Lease nor sublet the premises or any
portion thereof without the prior written consent of the Lessor, which consent
shall not be unreasonably withheld.  An acceptance of a permitted assignment of
this Lease, or sublease of the premises, by any person shall be construed as a
promise on the part of such assignee or sublessor to be bound by and perform all
of the agreements of Lessee herein contained.

     12.  Lessee may make non-structural alternations, additions, or
improvements to the premises, including without limitation, erection or
installation of signs, as Lessee deems necessary for its purposes.  Unless the
parties hereto agree otherwise in writing, prior to the termination of this
Lease all such non-structural alterations, additions or improvements shall be
removed and the premises restored to its original condition by Lessee at its
expense or, at Lessor's election, remain in place and become the property of
Lessor.

     13.  Lessee agrees not to make any contract for the construction,
alteration, addition, repair, or improvement of, or to, the premises, or any
part thereof, without providing in such contract that no lien of mechanics or
materialmen shall be created or shall arise against the premises, building, or
improvements at any time located on said premises.  All persons furnishing any
work, labor or materials for the Lessee, as well as other persons whatsoever,
are hereby given notice that no mechanics lien, materialmen's lien, or any
other encumbrance made by or obtained against the Lessee, or its interest in

                                       5
<PAGE>
   
said premises, buildings, or other improvements on said premises, shall in any
manner or degree affect the title or interest of the Lessor in the premises,
buildings, or other improvements thereon.

     14.  Lessee agrees to comply with all present and future statutes, laws,
ordinances, enactments, rules, regulations, orders, decrees, directives,
mandates or other similar requirements of any federal, state or local
government, court of public authority prohibiting, regulating or otherwise
relating to environmental pollution and environmental control of any kind,
including, but not limited to, air pollution, water pollution, noise pollution,
solid waste pollution and toxic substance control ("Environmental
Requirements"), including, but not limited to, Environmental Requirements under
the Environmental Laws, which are applicable to or arise out of or in connection
with Lessee's use or occupancy of the premises.  Lessee further agrees to comply
with such Environmental Requirements at its sole cost and expense and will hold
harmless, indemnify and defend Lessor from and against any claims, suits,
damages, losses, costs and expenses, including reasonable attorneys' fees, made
against or sustained by Lessor as a result of Lessee's failure to comply with
any Environmental Requirements.

     Lessee will comply with all existing and future federal, state, county and
local statutes, laws, enactments, ordinances, rules, regulations, orders and
other governmental requirements ("Governmental Requirements") applicable to
Lessee's use or occupancy of the premises, including, but not limited to,
workmen's compensation laws and the Occupational Safety and Health Act of 1970
and all governmental Requirements issued thereunder, and hold harmless,
indemnify and defend Lessor from and against any claims, actions, damages,
losses, costs and expenses, including reasonable attorneys' fees, made against
or sustained by Lessor as a result of Lessee's failure to comply with the
Governmental Requirements.

     15.  This Lease may, at Lessor's election, be terminated by Lessor in the
event of a breach by Lessee of any of its material agreements herein contained,
unless Lessee cures such breach within thirty (30) days of the date of receipt
by Lessee of notice thereof from Lessor, except as otherwise provided by
paragraph 16 and except that any default in payment of rent must be cured within
five (5) days of the date of receipt of such notice.

                                       6
<PAGE>
 
     If Lessor defaults in any of its covenants and agreements herein contained,
if any of the representations and warranties made by Lessor herein were untrue
when made or if, at any time during the term hereof, Lessee determines, by
whatever means, that the premises contain a hazardous material in violation of
an environmental law or regulation not introduced by or through Lessee or its
suppliers or contractors (other than the "Pre-Existing Condition"), Lessee may
elect either of the following if after not less than thirty (30) days prior
written notice to Lessor, Lessor has not cured the default or, within such time,
commenced and diligently pursued the cure of such default:

          a.   Lessee may remedy such default by any reasonably necessary
               action, and in connection with such remedy may pay expenses and
               employ counsel. All reasonable sums expended or obligations
               incurred by Lessee in connection therewith, including, but not
               limited to, reasonable attorneys' fees, shall be paid by Lessor
               to Lessee on demand, and on failure of such reimbursement, Lessee
               may, in addition to any other right or remedy that Lessee may
               have, deduct the costs and expenses thereof from rent or other
               payments subsequently becoming due hereunder; and

          b.   if the Lessor's default is material, elect to terminate this 
               Lease on at least thirty (30) days prior written notice to
               Lessor thereby terminating this Lease on the date designated in
               such notice;

provided, however, that if the default involves an environmental violation (i)
not caused by or through Lessee or by its suppliers or contractors, (ii)
separate and distinct from any condition or event arising out of or relating to
the Pre-Existing Condition and (iii) which a mutually agreeable contractor
reasonably expects would exceed $20,000 to cure, subparagraph a shall not
apply, and Lessor may, without any liability to Lessee, elect to terminate this
Lease without making any effort to cure.  The foregoing notwithstanding, Lessor
will indemnify Lessee for and hold it harmless from any environmental liability
and reimburse Lessee for cost associated with such indemnification, including,
but not limited to, reasonable attorneys' fees, for conditions on the premises
prior to commencement of this Lease, including but not limited to the Pre-
Existing Condition.

     16.  Lessor may, at its option, and without releasing Lessee from any
liability hereunder, terminate this Lease:

          a.   if any violation of an environmental law, rule or regulation
               caused by or through Lessee, or its suppliers and contractors
               occurs and is not fully remedied within thirty (30) days after
               the Lessee first has knowledge thereof, or, if the violation
               cannot be remediated within thirty (30) days with reasonable
               diligence, if Lessee has not begun 

                                       7
<PAGE>
 
               appropriate remediation within such thirty (30) day period and
               thereafter diligently pursued the necessary corrective measures
               to completion; or

          b.   if a petition in bankruptcy shall be filed by or against Lessee,
               or if Lessee shall file a petition seeking to reorganize or be
               adjudged bankrupt or insolvent by any court, or if a receiver or
               trustee shall be appointed in any suit or proceedings brought by
               or against Lessee, or if an attachment or execution shall be
               issued and levied against property of the Lessee, and the same
               shall not be fully released within thirty (30) days.

     17.  If Lessee shall abandon or vacate the premises prior to the
termination of this Lease, Lessor may, but shall not be obligated to, relet the
premises for such rent and on such terms as Lessor may see fit; and, if a
sufficient sum shall not be thus realized, after paying all expenses, including,
but not limited to, reasonable attorney's fees and costs, of such reletting, to
satisfy the rent hereby reserved and all other sums Lessee is required to pay
under this Lease, Lessee agrees to satisfy and pay all deficiencies.

     18.  A waiver by Lessor of any one instance of default by Lessee in the
performance of any provision of this Lease shall not be construed as a waiver of
any prior or subsequent default of the same or any of the terms of this Lease,
nor a relinquishment by Lessor of Lessor's right hereunder to have Lessee
perform this Lease in strict accordance with its provisions, time being of the
essence of this Lease.

     19.  The rights and remedies of Lessor under this Lease are not exclusive,
but shall be cumulative, and the exercise of any right or remedy by Lessor shall
not prevent the exercise of any other right or remedy by Lessor, whether
provided for by this Lease or by law or equity.  If Lessee fails to perform by
obligation under this Lease, Lessor may, but shall not be required to, perform
same and any expense incurred by Lessor in so doing shall become immediately due
and payable by Lessee as additional rent and shall bear interest at the rate of
twelve percent (12%) per year from the date paid by Lessor until repaid by
Lessee.

     20.  In the event any material portion of the premises hereby leased is
condemned under the power of eminent domain during the term of this Lease which
substantially impairs Lessee's intended use of the premises, this Lease may be
terminated at the election of either Lessor or Lessee upon not less than thirty
(30) days prior written 

                                       8
<PAGE>
 
notice of such election. The sums paid as compensation for such condemnation
shall be paid to Lessor, except that any part of such sum paid as compensation
for loss of Lessee's business and cost of Lessee's removal of stock and fixtures
shall belong to Lessee. The foregoing notwithstanding, if Lessee exercises its
purchase option, all condemnation compensation shall be paid to Lessee upon
completion of the purchase of the premises by Lessee.

     21.  All of Lessee's office equipment, personal property, manufacturing
equipment, removable improvements and fixtures erected in or attached to the
premises by the Lessee may be removed by the Lessee upon termination of this
Lease.

     22.  Notices of any kind by either the Lessor or the Lessee to the other
shall be written, dated, and signed by or on behalf of the party giving the
same.  Notice may be sent by certified or registered United States mail,
delivery restricted to addressee, postage prepaid, return receipt requested, by
hand delivery, or by a nationally recognized courier service, delivery
restricted to addressee, to Lessor and Lessee at the following addresses, unless
written notice is received by either party changing such address:

<PAGE>
 
                      Assumption, IL 62510-0029

     Any notice given pursuant to, and in accordance with, this paragraph shall
be considered complete on the date of mailing, hand delivery, or placement with
the courier.

     23.  All of the agreements, conditions and undertakings herein contained
shall extend to and be binding on the representatives and permitted successors
and assigns of the respective parties hereto.

     24.  Notwithstanding the agreements herein contained, it is expressly
understood that no partnership or joint venture is created hereby, nor shall
Lessor be considered or held out to be Lessee's agent, the relationship created
by this Lease being solely that of landlord and tenant.

     25.  This Lease contains the entire agreement of the parties and, except as
contained herein, no representations, warranties or agreements have been made by
either party, or their agents or representatives, to or with the other.  This
Lease shall be executed in duplicate, each such executed copy to be considered
an original.

     26.  Lessee agrees at the expiration or earlier termination of this Lease
to give peaceful possession of the premises to Lessor.

     27.  Damages to buildings and improvements located on the premises caused
by Lessee, its agents or employees, or an invitee of Lessee shall be promptly
repaired by Lessee at Lessee's cost and there shall be no abatement or
termination of rent because of such damage.  Lessee shall be entitled to apply
the proceeds of insurance provided by Lessee to pay for such repairs.  In lieu
of such repairs, Lessee may promptly exercise its purchase option under
paragraph 28, without any decrease in the purchase price because of such damage.
In such case, the damage shall be deemed to have occurred after the notice of
exercise for purposes of applying the insurance provisions of paragraph 28(f).

     In case of damage to the buildings and improvements on the premises which
Lessee is not required to repair under any provision of this Lease, Lessor may,
if such damage costs more than Fifty Thousand Dollars ($50,000.00) to repair
(based on reliable contractor's estimate), at its option, repair such damage
with reasonable promptness after Lessor is notified of such damage.  If Lessor
elects to repair the premises, it must give Lessee notice within 30 days of the
date of casualty of such election 

                                       10
<PAGE>
   
and it shall be required to repair Lessee's additions, improvements and
alterations, if any. The proceeds of insurance which Lessee is required to
provide under paragraph 8 shall be paid to Lessor to the extent of such damage
except that any proceeds payable under Lessee's insurance for damage to Lessee's
inventory, equipment and other personal property and improvements, additions and
alterations made by Lessee which Lessor does not repair shall be paid to Lessee.
In the event Lessor, in its sole discretion, determines not to repair such
damage, either the Lessee or the Lessor may terminate this Lease within 30 days
of the date of casualty by written notice without liability to the other except
for performance of the parties' respective obligations hereunder through the
date of such termination; provided, however, that if Lessee elects to exercise
the option to purchase as specified in paragraph 28 (without any reduction in
the purchase price because of such damage), Lessor shall assign to Lessee the
rights in insurance proceeds received by reason of such casualty from insurance
provided by Lessee under this Lease.

     28.  As further consideration for the Lessee's agreements hereunder, Lessor
gives the option to Lessee to purchase the premises for the sum of Two Hundred
Seventy Five Thousand Dollars ($275,000.00) and the approximately 20 acres
adjacent to the west boundary line of the premises and owned by Lessor, the
legal description of which is set forth on Exhibit B hereto (the "Farmland"),
subject to the following:

     a.   This option shall be exercisable by Lessee giving written notice to
          Lessor of its exercise at least thirty (30) days prior to the
          expiration date of the Lease.  The option may be exercised for just
          the premises or for the premises and the Farmland but not for just the
          Farmland.

     b.   The Lease shall continue in effect until the sale is closed.  All
          obligations of Lessee through the date of closing of the sale must be
          performed at or before closing.

     c.   Within 30 days of Lessor's receipt of Lessee's notice, Lessor shall
          furnish, at its expense, a commitment for an Owner's Title Insurance
          Policy for the full sale price, showing good and merchantable title to
          the premises and/or the Farmland in Lessor subject to the standard
          exceptions contained in such policy. Lessee shall have thirty (30)
          days after Lessee's receipt of such evidence of title to submit any
          objections to title to Lessor.  Any such objection must be submitted
          in writing, and any objections which are not timely submitted shall be
          deemed waived.  Lessor shall have a reasonable time to cure the same
          at Lessor's expense; provided, however, 

                                       11

          that Lessee may elect to take such title with a reasonable reduction
          of the purchase price if Lessor is unable to cure the same by the
          closing date.

     d.   Closing shall occur at Lessor's office at Paris, Illinois, or such
          other place as the parties may agree, forty-five (45) days after the
          date of Lessee's receipt of the aforementioned title insurance policy.

     e.   Payment of the purchase price for the premises shall be paid in cash
          at closing, subject to Lessor delivering to Lessee a trustee's deed
          for the premises in form and content satisfactory to Lessee.  Lessor
          shall agree in writing at the time of the closing of either the
          premises or the Farmland to indemnify and hold harmless Lessee from
          any liability, and to reimburse Lessee for any costs or expenses
          incurred by Lessee, arising out of, related to or in connection with
          any environmental condition existing on, under or in the premises on
          the date hereof, including, but not limited to, the Pre-Existing
          Condition.

     f.   If Lessee purchases the premises but does not purchase the Farmland at
          the same time, Lessee shall have a nonexclusive option, along with a
          right of first refusal, to purchase the Farmland until July 12, 2006.
          Under the right of first refusal, Lessee shall have thirty (30) days
          to purchase the Farmland after receipt of notice from Lessor that
          Lessor has received a bona fide written offer to buy the Farmland from
          an unrelated third party (the "Offer").  Such notice shall be
          accompanied by a copy of the Offer.  Lessee's right to purchase shall
          be for the same purchase price and other terms and conditions as are
          contained in the Offer.  If Lessee declines to purchase the Farmland
          during such 30 day period, Lessor shall be free to sell the Farmland
          to such offeror on terms and conditions identical to those provided to
          Lessee.

     g.   Unless the terms of the Offer provide otherwise, the payment for the
          Farmland shall be effected by delivering to Lessor a warranty deed
          transferring from Lessee to Lessor title to farmland in Edgar County
          (the "Traded Farmland"), subject to Lessor delivering to Lessee a
          trustee's deed for the Farmland, both of which deeds shall be in form
          and content satisfactory to the recipient thereof. The Traded Farmland
          shall have an appraised value equal to the appraised value of the
          Farmland and shall be selected by Lessor within __ days prior to the
          date of the closing.  The appraisal of both parcels of farmland shall
          be performed by a mutually agreeable appraiser, the cost of which
          shall be shared equally by both parties.

     29.  This Lease is executed by The Edgar County Bank & Trust Co., not
personally, but as Trustee as aforesaid, in the exercise of the power and
authority

premises. All alterations, improvements, additions or fixtures, whether

premises at the expiration or sooner determination of this lease and become the

lease, have given written notice to Lessee to remove the same, in which event
Lessee will remove such alterations, improvements and additions and restore the

than at the date of execution of this lease, or employ any person or persons 
objectionable to the fire insurance companies or carry or have any benzine or 
explosive matter of any kind in and about the demised premises. In case of a

agrees to pay to Lessor as additional rent any and all increase or increases of

     (b)  At any time or times and from time to time make such reasonable rules 
and regulations as may be necessary or desirable for the safety, care, and 
cleanliness of the demised premises and/or of the building of which the demised 
premises is a part and of real and personal property contained therein and for 
the preservation of good order. Such rules and regulations shall, when 
communicated in writing to Lessee, form a part of this lease.

Sale or Rent, Sign Prospective Purchasers or Tenants

     (c)  To display a "For Sale" sign at any time, and also, after notice from 
either party of intention to determine this lease, or at anytime within three 
months prior to the expiration of this lease, a "For Rent" sign, or both "For 
Rent" and "For Sale" signs; and all of said signs shall be placed upon such part
of the premises as Lessor may elect and may contain such matter as Lessor shall 
require. Persons authorized by Lessor may inspect the premises at reasonable 
hours during the said periods.

Discontinue Facilities and Service

     (d)  Lessor may discontinue at any time, any or all facilities furnished 
and services rendered by Lessor not expressly convenanted for herein or required
to be furnished or rendered by law; it being understood that they constitute no 
part of the consideration for this lease.

Responsibility of Lessee

     (a)  Lessee agrees to relieve and hereby relieves the Lessor from all 
liability by reason of any injury or damage to any person or property in the 
demised premises, whether belonging to the Lessee or any other person caused by 
any fire, breakage, or leakage in any part or portion of the building of which 
the demised premises is a part or from water, rain or snow that may leak into, 
issue or flow from any part of the said premises, or of the building of which 
the demised premises is a part, from the drains, pipes, or plumbing work of the 
same, or from any place or quarter, unless such breakage, leakage, injury or 
damage be caused by or result from the negligence of Lessor or its servants or 
agents.

     (b)  Lessee also agrees to relieve and hereby relieves Lessor from all 
liability by reason of any damage or injury to any property or to Lessee or 
Lessee's guests, servants or employees which may arise from or be due to the 
use, misuse or abuse of all or any of the elevators, hatches, openings, 
stairways, hallways of any kind whatsoever which may exist or hereafter be 
erected or constructed on the said premises or the sidewalks surrounding the 
building of which may arise from defective construction, failure of water 
supply, light, power, electric wiring, plumbing or machinery, wind, lightning, 
storm or any other cause whatsoever on the said premises or the building of 
which the demised premises is a part, unless such damage, injury, use, misuse or
abuse be caused by or result from the negligence of Lessor, its servants or 
agents.

Responsibility of Lessor
Total Destruction of Premises

     (a)  In the event the demised premises are totally destroyed or so damaged
by fire or other casualty that, in the opinion of a licensed architect retained
by Lessor, the same cannot be repaired and restored within ninety days from the
happening of such injury this lease shall absolutely cease and determine, and
the rent shall abate for the balance of the term.

Partial Destruction of Premises

     (b)  If the damage be only partial and such that the premises can be
restored, in the opinion of a licensed architect retained by Lessor, to
approximately their former condition within ninety days from the date of the
casualty loss Lessor may, at Lessor's option, restore the same with reasonable
promptness, reserving the right to enter upon the demised premises for that
purpose. Lessor also reserves the right to enter upon the demised premises
whenever necessary to repair damage caused by fire or other casualty to the
building of which the demised premises is a part, even though the effect of such
entry be to render the demised premises or a part thereof untenantable. In
either event the rent shall be apportioned and suspended during the time Lessor
is in possession, taking into account the proportion of the demised premises
rendered untenantable and the duration of Lessor's possession. If a dispute
arises as to the amount of rent due under this clause, Lessee agrees to pay the
full amount claimed by Lessor, but Lessee shall have the right to proceed by law
to recover the excess payment, if any.

Repairs by Lessor

     (c)  Lessor shall make such election to repair the premises or terminate 
this lease by giving notice thereof to Lessee at the leased premises within 
thirty days from the day Lessor received notice that the demised premises had 
been destroyed or damaged by fire or other casualty.

Damage for Interruption of Use

     (d)  Except to the extent hereinbefore provided, Lessor shall not be liable
for any damage, compensation, or claim by reason of the necessity of repairing 
any portion of the building, the interruption in the use of the premises, any 
inconvenience or annoyance arising as a result of such repairs or interruption, 
or the termination of this lease by reason of damage to or destruction of the 
premises.

Representation of Condition of Premises

     (e)  Lessor has let the demised premises in their present "as is" condition
and without any representations, other than those specifically endorsed hereon 
by Lessor, through its officers, employees, servants and/or agents. It is 
understood and agreed that Lessor is under no duty to make repairs, alterations,
or decorations at the inception of this lease or at any time thereafter unless 
such duty of Lessor shall be set forth in writing endorsed hereon.

Zoning

     (f)  It is understood and agreed that the Lessor hereof does not warrant or
undertake that the Lessee shall be able to obtain a permit under any Zoning 
Ordinance or Regulation for such use as Lessee intends to make of the said 
premises, and nothing in this lease contained shall obligate the Lessor to 
assist Lessee in obtaining said permit; the Lessee further agrees that in the 
event a permit cannot be obtained by Lessee under any Zoning Ordinance or 
Regulation, this lease shall not terminate without Lessor's consent, and the 
Lessee shall use the premises only in a manner permitted under such Zoning 
Ordinance or Regulation.

Miscellaneous Agreements and Conditions
Effect of Repairs on Rental

     (a)  No contract entered into or that may be subsequently entered into by 
Lessor with Lessee, relative to any alterations, additions, improvements or 
repairs, nor the failure of Lessor to make such alterations, additions, 
improvements or repairs as required by any such contract, nor the making by 
Lessor or his agents or contractors of such alterations, additions, improvements
or repairs shall in any way affect the payment of the rent or said other charges
at the time specified in this lease, expect to the extent and in the manner 
hereinbefore provided.

Agency

     (b)  It is hereby expressly agreed and understood that the 
said.......................................is acting as agent only and shall not
in any event be held liable to the owner or to Lessee for the fulfillment or 
non-fulfillment of any of the terms or conditions of this lease, or for any 
action or proceedings that may be taken by the owner against Lessee, or by 
Lessee against the owner.

Waiver of Custom

     (c)  It is hereby covenanted and agreed, any law, usage or custom to the 
contrary notwithstanding, that Lessor shall have the right at all times to 
enforce the covenants and provisions of this lease in strict accordance with the
terms hereof, notwithstanding any conduct or custom on the part of the Lessor in
refraining from so doing at any time or times; and, further, that the failure of
Lessor at any time or times to enforce has rights under said convenants and 
provisions strictly in accordance with the same shall not be construed as having
created a custom in any way or manner contrary to the specific terms, provisions
and covenants of this lease or as having in any way or manner modified the same.

Conduct of Lessee

     (d)  This lease is granted upon the express condition that Lessee and/or 
the occupants of the premises herein leased shall not conduct themselves in a 
manner which is improper or objectionable, and if at any time during the term of
this lease or any extension or continuation thereof Lessee or any occupier of 
the said premises shall have conducted himself in a manner which is improper or 
objectionable, Lessee shall be taken to have broken the covenants and conditions
of this lease, and Lessor will be entitled to all of the rights and remedies 
granted and reserved herein, for the Lessee's failure to observe all of the 
covenants and conditions of this lease.

Failure of Lessee to Repair

     (e)  In the event of the failure of Lessee promptly to perform the 
covenants of Section 8(b) hereof, Lessor may go upon the demised premises and 
perform such covenants, the cost thereof, at the sole option of Lessor, to be 
charged to Lessee as additional and delinquent rent.

Waiver of Subrogation

     (f)  Lessor and Lessee hereby agree that all insurance policies which each 
of them shall carry to insure the demised premises and the contents therein 
against casualty loss, and all liability policies which they shall carry 
pertaining to the use and occupancy of the demised premises shall contain 
waivers of the right of subrogation against Lessor and Lessee herein, their 
heirs, administrators, successors, and assigns.

Security Interest

     (g)  Lessee hereby grants to Lessor a security interest under the Uniform 
Commercial Code in all of Lessee's goods and property in, on, or about the 
demised premises. Said security interest shall secure unto Lessor the payment of
all rent (and charges collectible or reserved as rent) hereunder which shall 
become due under the provisions of this lease. Lessee hereby to execute, upon 
request of Lessor, such financing statements as may be required under the 
provisions of the said Uniform Commercial Code to perfect a security interest in
Lessee's said goods and property.

Remedies of Lessor

     If the Lessee
     (a)  Does not pay in full when due any and all installments of rent and/or 
any other charge or payment herein reserved, included, or agreed to be treated 
or collected as rent and/or any other charge, expense, or cost herein agreed to 
be paid by the Lessee, or 

     (b)  Violates or fails to perform or otherwise breaks any covenant or 
agreement herein contained; or

     (c)  Vacates the demised premises or removes or attempts to remove or 
manifests an intention to remove any goods or property therefrom otherwise than 
in the ordinary and usual course of business without having first paid and 
satisfied the Lessor in full for all rent and other charges then due or that may
thereafter become due until the expiration of the then current term, above 
mentioned; or

     (d)  Becomes embarrassed or insolvent, or makes an assignment for the 
benefit of creditors, or if a petition in bankruptcy is filed by or against 
Lessee or a complaint in equity or other proceedings for the appointment of a 
receiver for Lessee is filed, or if proceedings for reorganization or for 
composition with creditors under any State or Federal law be instituted by or 
against Lessee, or if the real or personal property of Lessee shall be levied 
upon or be sold, or if for any other reason Lessor shall, in good faith, believe
that Lessee's ability to comply with the covenants of this lease, including the 
prompt payment of rent hereunder, is or may become impaired,

        thereupon:
     (1)  The whole balance of rent and other charges, payments, costs, and 
expenses herein agreed to be paid by Lessee, or any part thereof, and also all 
costs and officers' commissions including watchmen's wages shall be taken to be
due and payable and in arrears as if by the terms and provisions of this lease
said balance of rent and other charges, payment, taxes, costs and expenses were
on that date, payable in advance. Further, if this lease or any part thereof is
assigned, or if the premises, or any part thereof is sub-let, Lessee hereby
irrevocably constitutes and appoints
<PAGE>
 
Lessor as Lessee's agent to collect the rents due from such assignee or 
sub-lessee and apply the same to the rent due hereunder without in any way 
affecting Lessee's obligation to pay any unpaid balance of rent due hereunder; 
or

     (2) At the option of Lessor, this lease and the terms hereby created shall 
determine and become absolutely void without any right on the part of Lessee to 
reinstate this lease by payment of any sum due or by other performance of any 
condition, term, or covenant broken; whereupon, Lessor shall be entitled to 
recover damages for such breach in an amount equal to the amount of rent 
reserved for the balance of the term of this lease, less the fair rental value 
of the said demised premises for the remainder of the lease term.


15. Further Remedies of Lessor

     In the event of any default as above set forth in Section 14, Lessor, or 
anyone acting on Lessor's behalf, at Lessor's option:

     (a) May let said premises or any part or parts thereof to such person or 
persons as may, in Lessor's discretion, be best; and Lessee shall be liable for 
any loss of rent for the balance of the then current term. Any such re-entry or 
re-letting by Lessor under the terms hereof shall be without prejudice to 
Lessor's claim for actual damages, and shall under no circumstances, release 
Lessee from liability for such damages arising out of the breach of any of the 
covenants, terms, and conditions of this lease.

breached the terms of such lease agreement; subject, however, to all of the 
rights granted or created by any such Statute, Act of Assembly, or other law of 
this state existing for the protection and benefit of tenants; and

     (d) May have and exercise any and all other rights and remedies contained 
in this lease agreement, including the rights and remedies provided by Sections 
16 and 17 hereof.

16. Confession of Judgment for Money

     Lessee covenants and agrees that if the rent and/or any charges reserved in
this lease as rent (including all accelerations of rent permissible under the
provisions of this lease) shall remain unpaid five (5) days after the same is
required to be paid, then and in that event, Lessor may cause Judgment to be
entered against Lessee, and for that purpose Lessee hereby authorizes and
empowers Lessor or any Prothonotary, Clerk of Court or Attorney of any Court of
Record to appear for and confess judgment against Lessee and agrees that Lessor
may commence an action pursuant to Pennsylvania Rules of Civil Procedure No.
2950 et seq. for the recovery from Lessee of all rent hereunder (including all
accelerations of rent permissible under the provisions of this lease) and/or for
all charges reserved hereunder as rent, as well as for interest and costs and
Attorney's commission, for which authorization to confess judgment, this lease,
or a true and correct copy thereof, shall be sufficient warrant. Such Judgment
may be confessed against Lessee for the amount of rent in arrears (including all
accelerations of rent permissible under the provisions of this lease) and/or for
all charges reserved hereunder as rent, as well as for interest and costs;
together with an attorney's commission of five percent (5%) of the full amount
of Lessor's claim against Lessee. Neither the right to institute an action
pursuant to Pennsylvania Rules of Civil Procedure No. 2950 et seq. nor the
authority to confess judgment granted herein shall be exhausted by one or more
exercises thereof, but successive complaints may be filed and successive
judgments may be entered for the aforedescribed sums five days or more after
they become due as well as after the expiration of the original term and/or
during or after expiration of any extension or renewal of this lease.

17. Confession of Judgment for Possession of Real Property

     Lessee covenants and agrees that if this lease shall be terminated (either 
because of condition broken during the term of this lease or any renewal or 
extension thereof and/or when the term hereby created or any extension thereof 
shall have expired) then, and in that event, Lessor may cause a judgment in 
ejectment to be entered against Lessee for possession of the demised premises, 
and for that purpose Lessee hereby authorizes and empowers any Prothonotary, 
Clerk of Court or Attorney of any Court of Record to appear for Lessee and to 
confess judgment against Lessee in Ejectment for possession of the herein 
demised premises, and agrees that Lessor may commence an action pursuant to 
Pennsylvania Rules of Procedure No. 2970 et seq. for the entry of an order in 
Ejectment for the possession of real property, and Lessee further agrees that a 
Writ of Possession pursuant thereto may issue forthwith, for which authorization
to confess judgment and for the issuance of a writ or writs of possession 
pursuant thereto, this lease, or a true and correct copy thereof, shall be 
sufficient warrant. Lessee further covenants and agrees, that if for any reason 
whatsoever, after said action shall have commenced the action shall be 
terminated and the possession of the premises demised hereunder shall remain in 
or be restored to Lessee, Lessor shall have the right upon any subsequent 
default or defaults, or upon the termination of this lease as above set forth to
commence successive actions for possession of real property and to cause the 
entry of successive judgments by confession in Ejectment for possession of the 
premises demised hereunder.

18. Affidavit of Default

     In any procedure or action to enter Judgment by Confession for Money 
pursuant to Section 16 hereof, or to enter Judgment by Confession in Ejectment 
for possession of real property pursuant to Section 17 hereof, if Lessor shall 
first cause to be filed in such action an affidavit or averment of the facts 
constituting the default or occurrence of the condition precedent, or event, the
happening of which default, occurrence, or event authorizes and empowers Lessor 
to cause the entry of judgment by confession, such affidavit or averment shall 
be conclusive evidence of such facts, defaults, occurrences, conditions 
precedent, or events; and if a true copy of this lease (and of the truth of 
which such affidavit or averment shall be sufficient evidence) be filed in such 
procedure or action, it shall not be necessary to file the original as a Warrant
of Attorney, any rule of court, custom, or practice to the contrary 
notwithstanding.

19. Waivers by Lessee of Errors, Right of Appeal, Stay, Exemption, Inquisition

     Lessee hereby releases to Lessor and to any and all attorneys who may 
appear for Lessee all errors in any procedure or action to enter Judgment by
Confession by virtue of the warrants of attorney contained in this lease, and
all liability therefor. Lessee further authorizes the Prothonotary or any Clerk
of any Court of Record to issue a Writ of Execution or other process, and
further agrees that real estate may be sold on a Writ of Execution or other
process. If proceedings shall be commenced to recover possession of the demised
premises either at the end of the term or sooner termination of this lease, or
for non-payment of rent or for any other reason, Lessee specifically waives the
right to the three (3) months' notice to quit and/or the fifteen (15) or thirty
(30) days' notice to quit required by the Act of April 6, 1951, P.L. 69, as
amended, and agrees that five (5) days' notice shall be sufficient in either or
any such case.

20. Right of Assignee of Lessor

     The right to enter judgment against Lessee by confession and to enforce all
of the other provisions of this lease herein provided for may at the option of 
any assignee of this lease, be exercised by any assignee of the Lessor's right, 
title and interest in this lease in his, her, or their own name, any statute, 
rule of court, custom, or practice to the contrary notwithstanding.

21. Remedies Cumulative

     All of the remedies hereinbefore given to Lessor and all rights and 
remedies given to it by law and equity shall be cumulative and concurrent. No 
determination of this lease or the taking or recovering possession of the 
premises shall deprive Lessor of any of its remedies or actions against the 
Lessee for rent due at the time or which, under the terms hereof would in the 
future become due as if there had been no determination, nor shall the bringing 
of any action for rent or breach of covenant, or the resort to any other remedy 
herein provided for the recovery of rent be construed as a waiver of the right 
to obtain possession of the premises.

22. Condemnation

     In the event that the premises demised herein, or any part thereof, is 
taken or condemned for a public or quasi-public use, this lease shall, as to the
part so taken, terminate as of the date title shall vest in the condemnor, and 
rent shall abate in proportion to the square feet of leased space taken or 
condemned or shall cease if the entire premises be so taken. In either event the
Lessee waives all claims against the Lessor by reason of the complete or partial
taking of the demised premises.

23. Subordination     

     This Agreement of Lease and all its terms, covenants and provisions are and
each of them is subject and subordinate to any lease or other arrangement or 
right to possession, under which the Lessor is in Control of the demised 
premises, to the rights of the owner or owners of the demised premises and of 
the land or buildings of which the demised premises are a part, to all rights of
the Lessor's landlord and to any and all mortgages and other encumbrances now or
hereafter placed upon the demised premises or upon the land and/or the buildings
containing the same; and Lessee expressly agrees that if Lessor's tenancy, 
control, or right to possession shall terminate either by expiration, forfeiture
or otherwise, then this lease shall thereupon immediately terminate and the 
Lessee shall, thereupon, give immediate possession; and Lessee hereby waives any
and all claims for damages or otherwise by reason of such termination as 
aforesaid.

24. Termination of Lease

     It is hereby mutually agreed that either party hereto may determine this
lease at the end of said term by giving to the other party written notice
thereof at least sixty days prior thereto, but in default of such notice, this
lease shall continue upon the same terms and conditions in force immediately
prior to the expiration of the term hereof as are herein contained for a further
period of one year and so on from year to year unless or until terminated by
either party hereto, giving the other sixty days written notice for removal
previous to expiration of the then current term; PROVIDED, however, that should
this lease be continued for a further period under the terms hereinabove
mentioned, any allowances given Lessee on the rent during the original term
shall not extend beyond such original term, and further provided, however, that
if Lessor shall have given such written notice prior to the expiration of any
term hereby created, of his intention to change the terms and conditions of this
lease, and Lessee shall not within sixty days from such notice notify Lessor of
Lessee's intention to vacate the demised premises at the end of the then current
term, Lessee shall be considered as Lessee under the terms and conditions
mentioned in such notice for a further term as above provided, or for such
further term as may be stated in such notice. In the event that Lessee shall
give notice, as stipulated in this lease, of intention to vacate the demised
premises at the end of the present term, or any renewal or extension thereof,
and shall fail or refuse so to vacate the same on the date designated by such
notice, then it is expressly agreed that Lessor shall have the option either 
(a) to disregard the notice so given as having no effect, in which case all the
terms and conditions of this lease shall continue thereafter with full force
precisely as if such notice had not been given, or (b) Lessor may, at any time
within thirty days after the present term or any renewal or extension thereof,
as aforesaid, give the said Lessee ten days' written notice of his intention to
terminate the said lease; whereupon the lessee expressly agrees to vacate said
premises at the expiration of the said period of ten days specified in said
notice. All powers granted to Lessor by this lease may be exercised and all
obligations imposed upon Lessee by this lease shall be performed by Lessee as
well during any extension of the original term of this lease as during the
original term itself.

26. Lease Contains all Agreements

     It is expressly understood and agreed by and between the parties hereto 
that this lease and the riders attached hereto and forming a part hereof set 
forth all the promises, agreements, conditions and understandings between Lessor
or his Agent and Lessee relative to the demised premises, and that there are no 
promises, agreements, conditions or understandings, either oral or written, 
between them other than herein set forth. It is further understood and agreed 
that, except as herein otherwise provided, no subsequent alteration, amendment, 
change or addition to this lease shall be binding upon Lessor or Lessee unless 
reduced to writing and signed by them.

27. Heirs and Assignees

     All rights and liabilities herein given to, or imposed upon, the respective

the terms, covenants and agreements herein, and the word "Lessee" shall be 
deemed and taken to mean each and every person or party mentioned as a Lessee 
herein, be the same one or more; and if there shall be more than one Lessee, any
notice required or permitted by the terms of this lease may be given by or to 
any one thereof, and shall have the same force and effect as if given by or to 
all thereof. The words "his" and "him" wherever stated herein, shall be deemed 
to refer to the "Lessor" or "Lessee" whether such Lessor or Lessee be singular 
or plural and irrespective of gender. No rights, however, shall inure to the 
benefit of any assignee of Lessee unless the assignment to such assignee has
been approved by Lessor in writing as aforesaid.

28. Security Deposit

     Lessee does herewith deposit with Lessor the sum of              Dollars, 
to be held as security for the full and faithful performance by Lessee of 
Lessee's obligations under this Lease and for the payment of damages to the 
demised premises. Said security deposit is to be held by Lessor as an Escrow 
Fund pursuant to the terms and provisions of the Penna Act of Assembly approved 
December 29, 1972, Act No. 363. Except for such sum as shall be lawfully applied
by Lessor to satisfy valid claims against Lessee arising from defaults under 
this lease or by reason of damages to the demised premises, the Escrow Fund 
shall be returned to Lessee at the expiration of the terms of this lease or any 
renewals or extensions thereof but as provided for in the said Act of Assembly. 
It is understood that no part of any security deposit or Escrow Fund is to be 
considered as the last rental due under the terms of the lease.

29. Headings no part of Lease

     Any headings preceding the text of the several paragraphs and 
sub-paragraphs hereof are inserted solely for convenience of reference and shall
not constitute a part of this lease nor shall they affect its meaning, 
construction or effect.

(other than Section 7.01(b) as it pertains to Buyer or Parent) to have been met
on or before January 30, 1996, (ii) a default by Seller in a material obligation
hereunder, which default is not cured within five (5) business days after
written notice thereof is given to Seller by Buyer, or (iii) the termination of
this Agreement by Seller pursuant to Section 10.01(d) hereof, the Earnest Money,
plus all interest earned thereon, if any, shall be returned to Buyer.  In all
other events, the Earnest Money and accrued interest thereon shall be delivered
to Seller.  Upon the Closing, the Earnest Money will be delivered to Seller in
partial satisfaction of Buyer's obligations hereunder.  Seller and Buyer hereby
covenant and agree to direct the Escrow Agent to deliver the Earnest Money plus
interest earned thereon in accordance with the foregoing provisions.

<PAGE>
 
Liens other than Permitted Liens, the Seller's Assets and (ii) Owners, jointly
and severally, will sell, convey, assign, transfer and deliver to Buyer, and
Buyer shall purchase, acquire and accept from Owners, free and clear of any
Liens other than Permitted Liens, the Owners' Real Property (collectively the
"Acquisition"). Seller shall effect delivery of the Seller's Assets by
delivering them to Buyer's possession where such Assets reside at the locations
of the business in Macon, Mississippi, Sparks, Nevada and Assumption, Illinois.

     2.02.  Purchase Price.  Subject to Section 2.05 below, in consideration for
the Seller's Assets, Buyer will convey to Seller at the Closing the amount of
$13,200,000, payable as follows: (i) the Earnest Money which shall be delivered
by the Escrow Agent at the Closing; and (ii) a wire transfer of immediately
available funds in the amount of $12,950,000 to such banks and accounts thereat
as shall be specified in writing by Seller.  In consideration for Owners' Real
Property, Buyer will convey to Owners at the Closing the amount of $1,600,000,
payable by wire transfer to such bank or banks as shall be specified in writing
by Owners to Buyer.  Such aggregate amount, as it may be adjusted pursuant to
Section 2.05 hereof, is referred to as the "Purchase Price."

     2.03.  Instruments of Conveyance. The transfer of the Assets shall be
effected by the delivery (i) by Owners to Buyer of a duly executed general
warranty deed in substantially the form of Exhibit B hereto in the case of the
Owners' Real Property, (ii) by Seller to Buyer of duly executed bills of sale
substantially in the form of Exhibit C hereto in the case of the Seller's Assets
and (iii) by Seller or Owners, as appropriate, of such other instruments of
conveyance, transfer and assignment as shall be necessary in the reasonable
opinion of counsel for the Buyer to vest in Buyer good, valid and marketable
title to the Assets, free and clear of all Liens, other than Permitted Liens
(collectively, the "Transfer Documents").

     2.04.  Assumption of Liabilities.  At the Closing, Buyer shall assume, and
agrees to pay, perform and discharge when due, the Assumed Liabilities.  Under
no circumstances shall Buyer assume any liabilities or obligations of Seller,
including any liabilities or obligations associated with or incurred in
connection with the Business, other than the Assumed Liabilities.  All such
liabilities and obligations of Seller (the "Retained Liabilities") shall be
retained by Seller.

     2.05.  Adjustment of Purchase Price.  (a) Not later than 60 calendar days
after the Closing Date, Buyer shall deliver to Seller a combined balance sheet
of the Business as of the Closing Date (the "Closing Date Balance Sheet")
prepared by Buyer (which date of such delivery is hereinafter referred to as the
"Delivery Date").  The Closing Date Balance Sheet shall (i) be prepared from the
books and records of the Business, (ii) be based 

                                      -6-
<PAGE>
 
upon a physical inventory made on or about the Closing Date, which shall be
performed by Seller and observed by Buyer, (iii) contain the same components as
the Latest Balance Sheet and (iv) be prepared on the basis set forth in Schedule
2.05. The Closing Date Balance Sheet shall be subject to verification by
Seller's accountants not later than 20 business days after the Delivery Date.
Buyer shall give Seller access to all books, records and work papers prepared or
reviewed by Buyer in connection with the preparation of the Closing Date Balance
Sheet. In the event that the Closing Date Net Working Capital (as hereinafter
defined) is less than $3,800,000 (the "Required Net Working Capital"), as agreed
to collectively by Seller's accountants and Buyer not later than 10 business
days after Seller's accountants complete such verification, then subject to
paragraph (b) below not later than 5 business days thereafter, Seller shall pay
to Buyer in cash or other immediately available funds the amount by which the
Required Net Working Capital is in excess of the Closing Date Net Working
Capital. In the event that the Closing Date Net Working Capital is in excess of
the Required Net Working Capital, Buyer shall pay to Seller as aforesaid the
amount of such excess. As used herein, "Closing Date Net Working Capital" means
the Current Assets less Current Liabilities as of the Closing Date, both
containing the same components as the Latest Balance Sheet and prepared on the
basis set forth in Schedule 2.05.

     (b) In the event that Seller's accountants and Buyer cannot agree as to the
amount of the Closing Date Net Working Capital within the above-specified time
frame, Seller and Buyer shall select a firm of independent accountants
reasonably acceptable to Seller and Buyer, and such firm shall be responsible
for determining the amount of the Closing Date Net Working Capital for purposes
of this Section 2.05; provided, however, that the amount by which Required Net
Working Capital is different from the Closing Date Net Working Capital which is
not in dispute, if any, shall be paid as set forth above. The cost of such
determination by such other independent accountants shall be borne equally by
Seller and Buyer.

     2.06.  Allocation of Total Consideration. Buyer, Seller and Owners agree
to allocate the Total Consideration in a manner consistent with Schedule 2.06
hereto. Seller, Owners and Buyer agree that they shall use such allocation for
all business, tax, accounting and other purposes, including the preparation and
filing of IRS Form 8594.

     2.07.  Further Assurances. (a) Seller and (with respect to Owners' Real
Property) Owners agree that they will, at any time and from time to time, after
the date hereof, upon reasonable request of Buyer, use all reasonable efforts to
do, execute, acknowledge, and deliver or will cause to be done, executed,
acknowledged, and delivered, all such further acts, deeds, assignments,
transfers, conveyances and powers of attorney as may be reasonably required to
evidence or perfect further the sale, 

                                      -7-

assignment, transfer, conveyance and delivery of the Assets to Buyer, or to aid
or assist Buyer in reducing to its possession, title to and possession of any
and all of the Assets sold, assigned, transferred, conveyed and delivered
hereby.

     (b) Buyer agrees that it will, at any time and from time to time, after the
date hereof, upon reasonable request of Seller, use all reasonable efforts to
do, execute, acknowledge, and deliver or to cause to be done, executed,
acknowledged, and delivered, all such further acts, deeds, assignments,
transfers, conveyances and powers of attorney as may be required to aid or
assist Seller and (with respect to Owners' Real Property) Owners in the sale,
assignment, transfer, conveyance and delivery of the Assets to Buyer and the
assumption by Buyer of the Assumed Liabilities.

     2.08.  Referrals and Deliveries.  Following the Closing, (i) Seller shall 
as promptly as is reasonably practicable: (a) deliver to Buyer, in the form
received, with the addition of any required endorsements by Seller, any cash,
checks or other payments received by Seller with respect to the Current Assets
or otherwise directly related to the operations of the Business and included in
the Assets; (b) refer to Buyer any and all inquiries from customers or suppliers
of Seller relating to the Business; and (c) deliver to Buyer all purchase orders
received by Seller relating to the Business and (ii) Buyer shall as promptly as
reasonably practicable deliver to Seller, in the form received, any cash, checks
or other payments received by Buyer constituting or otherwise directly related
to the Excluded Assets.

     2.09.  Risk of Loss.  All risk of loss with respect to the Assets shall
remain with Seller until the Closing Date and shall pass to Buyer only at the
Closing.

     2.10.  Transfer Taxes, Etc.  All real estate transfer taxes and recording
fees and personal property transfer taxes, if any, payable in connection with
the transfer of the Assets shall be paid equally by Seller or Owners, on the one
hand, and Buyer, on the other. All other taxes payable in connection with the
transfer of the Assets and the assumption of the Assumed Liabilities, including
without limitation any taxes payable as a result of a gain upon such transfer
and assumption shall be paid by Seller or the Owners, as appropriate.

     2.11.  Proration of Certain Taxes.  All state and local ad valorem real
property taxes and personal property taxes pertaining to the Assets for the
taxable year for such taxes in which the Closing occurs shall be prorated
between Buyer and Seller or Owners to the Closing Date, based upon the taxes
levied for that taxable year by each applicable taxing body.

                                  ARTICLE III

                    REPRESENTATIONS AND WARRANTIES OF SELLER

     Seller hereby represents and warrants to Buyer (and acknowledges and
confirms that Buyer is relying on such representations and warranties in
connection with the purchase of the Assets), as follows:

     3.01.  Organization, Standing, and Authority.  Seller is a corporation duly
organized, validly existing and in good standing under the laws of Delaware.
Seller is duly qualified to do business and in good standing in the States of
the United States and foreign jurisdictions where its ownership or leasing of
the Assets or the conduct of the Business requires it to be so qualified except
where the failure to be duly qualified would not have a Material Adverse Effect.
Seller has all necessary corporate power and authority to carry on the Business
as now conducted, to own, lease and operate the Assets, and to execute and
deliver, and to perform its obligations under, this Agreement.  Seller has in
effect all federal, state, local and foreign governmental authorizations
necessary for it to own the Assets, to lease the assets covered by the Leases
and to carry on the Business as it is now conducted.

     3.02.  Seller Subsidiaries.  Seller has no subsidiaries which carry on any
aspects of the Business or which provide products or services to or purchase
products or services from the Business.

     3.03.  Authority.  (a) The execution and delivery of this Agreement by
Seller, and the consummation by Seller of the transactions contemplated herein,
have been duly and validly authorized by all necessary corporate action on the
part of Seller.  This Agreement represents a valid and legally binding
obligation of Seller and each Owner, enforceable against Seller and each Owner
in accordance with its terms, except as the enforceability thereof may be
limited by bankruptcy, insolvency or other similar laws of general application
affecting the enforcement of creditors' rights or by general principles of
equity limiting the availability of equitable remedies.

     (b) Except as set forth on Schedule 3.03(b) hereto, neither the execution
and delivery of this Agreement by Seller or any Owner, nor the consummation by
Seller or any Owner of the transactions contemplated herein, nor compliance by
Seller with any of the provisions hereof, will as of the Closing Date (i)
conflict with or result in a breach of any provision of the articles of
incorporation or bylaws of Seller or (ii) constitute or result in the breach of
any term, condition, or provision of, or give rise to any right of termination,
cancellation, or acceleration with respect to, or result in the creation of any
Lien upon any of the Assets pursuant to, any note, bond, mortgage, 

                                      -9-
<PAGE>
 
indenture, license, agreement, lease or other instrument or obligation by which
the Business or any of the Assets may be subject or (iii) violate any order,
writ, injunction, decree, statute, rule or regulation applicable to Seller or
any Owner in connection with the Business or any of the Assets. Schedule 3.03(b)
hereto lists all approvals, authorizations, filings, registrations and
notifications required to be obtained or made by Seller in connection with the
consummation of the transactions contemplated hereby.

     3.04.  Financial Statements.  Financial Information; Books and Records (a)
The Latest Balance Sheet was prepared from the books and records of the Business
and fairly presents in all material respects the financial position of the
Business except (i) as otherwise disclosed therein, (ii) for those liabilities
for debt obligations of Seller to LaSalle National Bank and The CIT
Group/Equipment Financing, Inc., which persons have related liens on accounts
receivable, inventories and equipment, and (iii) the net book value of property,
plant and equipment should be approximately $250,000 higher due to additions and
deletions to equipment (assets) and to refinements in calculations of
depreciation previously estimated.

     (b) The financial information previously provided to Buyer and referred to
in Schedule 3.04(b) was prepared from the books and records of the Seller and is
in all material respects a complete and correct presentation of the information
shown; provided, however, that any financial projections provided by Seller
(while as of their date of preparation represented good faith estimates based on
information available to Seller at the time) contain assumptions relating to
future events which may or may not occur.

     (c) The books and records of the Seller described in Schedule 3.04(c) and
the books and records of the Seller from which the Latest Balance Sheet was
prepared and the information referred to in Section 3.04(b) was taken were
prepared in the ordinary course of business of the Seller and accurately reflect
in all material respects all transactions of the Business of the nature required
by applicable accounting requirements and by law to be contained in such books
and records.

     3.05.  Absence of Undisclosed Liabilities.  The Business has no obligation
or liability (contingent or otherwise) that would reasonably be expected to have
a Material Adverse Effect, except as reflected in the Latest Balance Sheet.

     3.06.  [Intentionally Left Blank]

     3.07.  Compliance with Laws; Condemnation.  (a) Seller:

          (i) Is in compliance with all laws, regulations, reporting and
     licensing requirements and orders applicable to 

                                      -10-
<PAGE>
 
     the Business or to the Employees, the breach or violations of which would
     have a Material Adverse Effect, and has no reason to believe that any audit
     or review by any federal, state, local or foreign regulatory authority
     would disclose any non-compliance or violation which would, either
     individually or in the aggregate, have a Material Adverse Effect; and

          (ii) Has received no notification or communication from any agency or
     department of federal, state, local or foreign government or the staff
     thereof or from any self-regulatory body (A) asserting that, or commencing
     an investigation as to whether, Seller is not in compliance with any of the
     statutes, regulations or ordinances which such governmental authority or
     self-regulatory body enforces, which, as a result of such noncompliance in
     any such instance, would have a Material Adverse Effect, or (B) threatening
     to revoke any license, franchise, permit or governmental authorization,
     which revocations would have a Material Adverse Effect.

     (b) None of the Assets is subject to any governmental decree or order or is
being condemned, expropriated or otherwise taken by any public authority with or
without compensation, or, to Seller's knowledge, that any such condemnation,
expropriation or taking has been proposed.

     3.08.  Employee Benefit Plans.  (a) Schedule 3.08(a) hereto discloses (i) 
all "employee benefit plans," as defined in Section 3(3) of the Employee
Retirement Income Security Act of 1974, as amended "ERISA"), and any other
formal or informal employee pension, welfare and/or fringe benefit arrangements
or payroll practices, including without limitation, severance pay, sick leave,
vacation pay, salary continuation for disability, compensation, bonus, stock
purchase, hospitalization, medical insurance, life insurance, and scholarship
programs maintained by Seller or to which Seller contributed or is obligated to
contribute thereunder, whether legally binding or not, for the benefit of the
current or former employees of Seller who are or were employed primarily in the
Business ("Employee Benefit Plans"), (ii) all such Employee Benefit Plans which
are also "employee pension benefit plans," as defined in Section 3(2) of ERISA,
and which are subject to Title IV of ERISA, maintained by Seller, or any
corporation, trade or business which is or was under common control with Seller
or treated as a single employer with Seller under Sections 414(b), (c), (m) or
(o) of the Code "ERISA Affiliate") or to which Seller or any ERISA Affiliate
contributed or is obligated to contribute thereunder ("Pension Plans"), and
(iii) any collective bargaining agreements to which Seller is or has been a
party covering any Employees.

     (b) The Employee Benefit Plans intended to qualify under Section 401(a) of
the Code have been determined by the Internal Revenue Service to so qualify and
each trust maintained pursuant thereto has been determined to be exempt from
federal 

                                      -11-
<PAGE>
 
income taxation under Section 501(a) of the Code (or has been submitted for such
a determination within the applicable remedial amendment period); all
contributions due and owing thereto have been made, and to the knowledge of
Seller nothing has occurred with respect to the operation of the Employee
Benefit Plans which would cause the loss of such qualification or exemption.

     (c) True and complete copies of the following documents with respect to
each of the Employee Benefit Plans have been made available to Buyer by Seller:
(i) any plans and amendments thereto, (ii) the last IRS determination letter,
(iii) summary plan descriptions, (iv) written communications to employees
relating to the Employee Benefits Plans and (v) written descriptions of all non-
written agreements, promises or understandings relating to the Employee Benefits
Plans.

     (d) The Employee Benefit Plans have been maintained, in all material
respects, in accordance with their terms and with all provisions of ERISA
(including rules and regulations thereunder) and other applicable law, including
without limitation all applicable reporting and disclosure requirements.

     (e) Seller maintains no Employee Benefit Plans which are "employee welfare
benefit plans" within the meaning of Section 3(l) of ERISA and which provide for
continuing benefits or coverage for any participant or any beneficiary of a
participant after retirement or other termination of employment, except as may
be required under Part 6 of Subtitle B of Title I of ERISA and at the sole
expense of the participant or the participant's beneficiary. Seller and each of
the ERISA Affiliates which maintains a "group health plan" within the meaning of
Section 5000(b)(1) of the Code has complied in all material respects with the
notice and continuation coverage requirements of Part 6 of Subtitle B of Title I
of ERISA.

     (f) Except as disclosed in Schedule 3.08(f) hereto, neither the execution
and delivery of this Agreement nor the consummation of the transactions
contemplated hereby will result in any payment becoming due to any Employee of
Seller (including, without limitation, severance pay, unemployment compensation
or similar payment), not including any such payments which may become due in
connection with any actions taken by Buyer after the Closing.

     (g) Except as disclosed on Schedule 3.08(g), Seller has no contract, plan,
or commitment, whether legally binding or not, to create any additional Employee
Benefit Plans or to modify any existing Employee Benefit Plan covering any
Employees.

contracts and commitments of the following types (each a "Material Contract") to

     (n) other agreements, contracts and commitments which individually have a
value of $25,000 or more.

No officer or other Employee of the Business is a party or subject to any
contract with Seller, or to the knowledge of Seller, any other person limiting
his or her freedom to compete with the Seller or such other person in the
performance of duties for Buyer following the Acquisition.

     3.10.  Material Contract Defaults.  Neither Seller nor any Owner is in
default under any Material Contract and there has not occurred any event that,

default.  To the knowledge of Seller, no other party to any Material Contract is
in material default thereunder.

     3.11.  Legal Proceedings.  Except as disclosed in Schedule 3.11 hereto, 
there are no legal, administrative or arbitration actions, suits or proceedings

obligations of Buyer under this Agreement, the Transfer Documents to which it is
a party and the Transitional Services Agreement (the "Guaranteed Obligations")
as and when such payment or performance shall become due in accordance with the
terms of such documents (the "Buyer Documents"). Parent's obligations under this

no way conditioned upon any attempt to collect from or proceed against the Buyer
or any other Person or any other event or circumstance. The obligations of the
Parent under this Section 9.01 are direct and primary obligations of the Parent
and are independent of the obligations of the Buyer for the Guaranteed
Obligations, and a separate action or actions may be brought against the Parent
regardless of whether action is brought against the Buyer or any other person or
whether the Buyer or any other person is joined in any such action or actions.

                                     -32-
<PAGE>
 
     (b) Obligations Absolute. The Parent agrees that the Guaranteed Obligations
will be paid and performed strictly in accordance with the terms of the Buyer
Documents, regardless of any law, regulation or order now or hereafter in effect
in any jurisdiction affecting the Guaranteed Obligations, any of the terms of
the Buyer Documents or the rights of the Seller or any other person with respect
thereto. To the fullest extent permitted by law, the obligations of the Parent
under this Section 9.01 shall be absolute, unconditional and irrevocable,
irrespective of any of the following:

          (i)    any lack of legality, validity, enforceability or allowability
     (in a bankruptcy, insolvency, reorganization, dissolution or similar
     proceeding, or otherwise), or any avoidance or subordination, in whole or
     in part, of any Buyer Document or any of the Guaranteed Obligations; or

          (ii)   any change in the time, place or manner of payment of, or in
     any other term of, any of the Guaranteed Obligations, or any other
     amendment or waiver of or any consent to departure from any Buyer Document;
     or

          (iii)  any impairment by the Seller or any other person of any
     recourse of the Parent against the Buyer or any other person; or

          (iv)   any bankruptcy, insolvency, reorganization, dissolution or
     similar proceedings with respect to, or any change, restructuring or
     termination of the corporate structure or existence of, the Buyer or any
     other person; or

          (v)    the release or agreement not to sue without reservation of
     rights of Buyer, any other Person liable in any way for payment or
     performance of the Guaranteed Obligations; or

          (vi)   the existence of any set-off right, or claim or any defense of
     any kind or nature, which Parent may have against Buyer or any other Person
     (other than Seller or Owners); or

          (vii)  the power or authority or lack of power or authority of Buyer
     to execute and deliver the Buyer Document; or

          (viii) the existence or non-existence of Buyer as a legal entity; or

          (ix)   the transfer by Buyer of all, or any part of, or any interest
     under the Buyer Documents.

     (c) Waivers, etc.  To the fullest extent permitted by law, the Parent
hereby waives promptness, diligence, notice of 

                                      -33-
<PAGE>
 
acceptance and any other notice with respect to any of the Guaranteed
Obligations and this Section 9.01, any requirement of acceptance hereof,
reliance hereon or knowledge hereof by the Seller, and any requirement that the
Seller exhaust any right or take any action against the Buyer or any other
person or any collateral or other direct or indirect security for any of the
Guaranteed Obligations.

     (d) Reinstatement. The obligations of Parent under this Section 9.01 shall
continue to be effective, or be automatically reinstated, as the case may be, if
at any time payment of any of the Guaranteed Obligations is avoided, rescinded
or must otherwise be returned by the Seller for any reason, all as though such
payment has not been made.

     (e) Subrogation, etc. Any rights which the Parent may have or acquire by
way of subrogation, reimbursement, exoneration, contribution or indemnity, and
any similar rights (whether arising by operation of law, by agreement or
otherwise), against the Buyer, arising from the existence, payment, performance
or enforcement of any of the obligations of the Parent under or in connection
with this Section 9.01, shall be subordinate in right of payment to the
Guaranteed Obligations, and the Parent shall not exercise any such rights until
all Guaranteed Obligations and all other obligations under this Section 9.01
have been paid in full.

     (f) Continuing Agreement. This Section 9.01 is a continuing guaranty and
shall continue in full force and effect until all Guaranteed Obligations and all
other amounts payable under this Section 9.01 have been paid and performed in
full.

     11.04.  Indemnification Procedures.

     (a)  Indemnification.  As used herein, with respect to Seller Damages, the
term "Indemnitor" shall mean Buyer, and "Indemnitee" shall mean Seller; with
respect to Buyer Damages, the term "Indemnitor" shall mean Seller, and
"Indemnitee" shall mean Buyer; the term "Damages" shall mean, as appropriate,
Seller Damages or Buyer Damages.  Promptly after the receipt by an Indemnitee of
notice or discovery of any Damages, whether or not giving rise to
indemnification rights hereunder, such Indemnitee will give the Indemnitor
written notice of such Damages (a "Claim") in accordance with paragraph (b) of
this section. If such Claim involves third parties, within fifteen days of
delivery of such written notice the Indemnitor may, at the expense of the
Indemnitor, elect to take all necessary steps properly to contest any Claim
involving third parties or to prosecute such Claim to conclusion or settlement
satisfactory to the Indemnitor.  If the Indemnitor makes the foregoing election,
the Indemnitee will have the right to participate at its own expense in all
proceedings.  If the Indemnitor does not make such election, the Indemnitee
shall be free to handle the prosecution or defense of any such Claim at the sole
cost of the Indemnitor and will timely notify the Indemnitor of the progress of
any such Claim, will permit the Indemnitor at the sole cost of the Indemnitor to
participate in such prosecution or defense and will provide the Indemnitor with
reasonable access to all relevant information and documentation relating to the
Claim and the Indemnitee's prosecution or defense thereof.  In any case, the
party not in control of the Claim will cooperate with the other party in the
conduct of the prosecution or defense of such Claim.  The Indemnitor shall have
the right to compromise or settle, with the Indemnitee's prior written consent
(which shall not be unreasonably withheld, conditioned or delayed, except no
such consent shall be required if such compromise or settlement involves only
the payment of money damages and does not impose an injunction or other
equitable relief upon the Indemnitee), any Claim.  In the event the Indemnitee
refuses to consent to any compromise or settlement recommended by the Indemnitor
which would have been concluded but for the Indemnitee's failure to give
consent, then the Indemnitor's liability to the Indemnitee hereunder with
respect to any such Claim which would have been barred by such compromise or
settlement shall not exceed the amount which the Indemnitor would have paid
pursuant to said proposed compromise or settlement.

                                      -37-
<PAGE>
 
     (b)  Notice of Claim. Each notice of a Claim by the Indemnitee (the "Notice
of Claim") will be in writing and will contain the following information to the
extent it is reasonably available to the Indemnitee:

          (i)  the Indemnitee's good faith estimate of the reasonably
     foreseeable amount of the alleged Damages (which amount, in the case of a
     Claim involving a third party, may be the amount of damages claimed by any
     third party plaintiff in an action brought against the Indemnitee based on
     alleged facts, which if true, would constitute a breach of the Indemnitor's
     representations and warranties); and

          (ii)  A brief description in reasonable detail of the facts,
     circumstances or events giving rise to the alleged Damages based on the
     Indemnitee's good faith belief thereof, including, without limitation, the
     identity and address of any third party claimant (to the extent reasonably
     available to the Indemnitee) and copies of any formal demand or complaint.

     (c)  Resolution of Notice of Claim.  Any Notice of Claim received by the
Indemnitor pursuant to paragraph (b) above will be resolved as follows:

          (i)  Uncontested Claims. In the event that Indemnitor does not contest
     a Notice of Claim in writing to Indemnitee within 20 calendar days after a
     Notice of Claim containing a statement of the claimed Damages is delivered
     pursuant hereto, Indemnitor shall pay the amount of Damages specified in
     the Notice of Claim within 20 days after delivery of such Notice of Claim.

          (ii)  Contested Claims.  Contested Claims (as hereinafter defined)
     shall be resolved by such dispute procedure as the parties shall agree to
     or failing such agreement by a proceeding brought in accordance with
     Section 12.03 hereof.  In the event that the Indemnitor gives written
     notice contesting all, or a portion of, a Notice of Claim to the Indemnitee
     (a "Contested Claim") within the 20-day period provided above, matters that
     are subject to third party claims brought against Buyer or Seller in a
     litigation or arbitration will await the final decision, award or
     settlement of such litigation.  Any portion of the Notice of Claim that is
     not contested will be resolved as set forth above in paragraph (c)(i).

     (d)  Product Warranty and Product Liability Claims. With respect to matters
covered by Section 11.02(v), Buyer shall promptly advise Seller in the event
that either (i) the amount of claims of the nature referred to therein is
reasonably expected to exceed $225,000 in any calendar year or (ii) Buyer has
received a substantial number of similar or repetitive claims. With respect

                                      -38-
<PAGE>
 
to Claims of the nature referred to in Section 11.02(iv), Buyer shall handle
such Claims in accordance with the normal procedures of Parent in respect of
product liability claims, which includes involvement of the Division President,
and in the same manner and with the same diligence as Parent handles such
claims.

     (e)  Other Matters. The provisions of this Section 11.04 shall apply to all
Claims except that, notwithstanding Section 11.04(a), with respect to any Claim
under Section 11.02(i) involving third parties which, together with all Claims
theretofore made under such Section, does not exceed the Threshold Amount, Buyer
shall be entitled to prosecute or defend such Claim in good faith using the same
prudence and business judgment as Parent would use if Buyer had no
indemnification rights hereunder, until such time as Seller shall reasonably
determine that the Threshold Amount has been or is likely to be exceeded, at
which time Seller shall be entitled to assume such prosecution or defense in
accordance with Section 11.04. If the Threshold Amount is so exceeded the cost
of such defense or prosecution shall be included in the Claim.

     Section 11.05.  Limitations.  Notwithstanding anything to the contrary set
forth in this Article XI:

     (a)  In the event that before the Closing Date Seller notifies Buyer of any
development which causes any representation, warranty or covenant made by or on
behalf of Seller or any Owner in any Transaction Document to be incorrect or
breached in any material respect, specifying such development and each such
representation, warranty or covenant and within 24 hours of receipt of such
notice, Buyer shall not have advised Seller that Buyer does not waive such
breach, each such representation, warranty or covenant shall be deemed amended
to the extent, but only to the extent, necessary to reflect such development. If
Buyer elects not to waive such breach, then this Agreement shall terminate in
accordance with the provisions of Section 10.02 hereof and the Escrow Agent
shall return the Earnest Money, together with accrued interest thereon, to
Buyer.

     (b)  In the event that Buyer elects to close the Acquisition despite the
fact that Buyer has actual knowledge of a fact or circumstance which causes one
or more of the conditions set forth in Section 7.01 not to have been fulfilled,
Buyer shall be deemed to have waived such condition or conditions to the extent,
but only to the extent, of such fact or circumstance and shall have no Claim
against Seller or any Owner with respect to such fact or circumstance;

     (c)  Seller shall not have any obligation to indemnify any Indemnified
Buyer Person (i) with respect to any Claim as to any matters referred to in
Section 11.02(i) (other than a breach of the representations and warranties set
forth in Section 3.25) unless and until the aggregate amount of all Claims under

                                      -39-
<PAGE>
 
Section 11.02(i) exceeds $400,000 (the "Threshold Amount"); provided that once
the aggregate amount of all Claims under Section 11.02(i) exceeds the Threshold
Amount the Claims which would otherwise be excluded from indemnification by
virtue of this clause (i) shall no longer be so excluded and (ii) subject to
clause (e) of this Section 11.05, with respect to any Claims, once the aggregate
amount of all Claims paid by Seller hereunder equal $7,500,000; and

     (d) In the event that the aggregate amount received by Buyer from the
Closing Date through the six month anniversary of the Closing Date from the
collection of the accounts receivable reflected on the Closing Date Balance
Sheet ("Closing Receivables") shall be less than the amount of the Closing
Receivables (net of any applicable reserve) reflected on such Closing Date
Balance Sheet, Seller shall, on demand from Buyer, repurchase from Buyer, the
uncollected Closing Receivables at the face amount thereof.  In determining
whether a particular Closing Receivable has been paid, Buyer shall apply
payments received from customers on a "first in - first out" basis unless the
customer shall specify that a particular payment is for a particular invoice or
in the case of an on account payment a particular amount is in dispute.  Buyer
shall sell such Closing Receivables to Seller without representation or warranty
of any kind except that Buyer shall warrant that the Closing Receivables sold
are free of Liens in favor of any person claiming by, through or under Buyer.

     (e) The provisions of this Article XI shall constitute the exclusive remedy
of all Buyer Indemnified Persons and Seller Indemnified Persons for any and all
claims by any such person against any party hereto relating to the Transaction
Documents or the Buyer Documents and the transactions contemplated hereby or
thereby except for suits or proceedings permitted or contemplated by Section
10.02 or 12.04 hereof.

     12.02.  Counterparts.  This Agreement may be executed in counterparts
(including executed counterparts delivered and exchanged by facsimile
transmission) each of which shall be deemed to constitute an original, but all
of which together shall constitute one and the same instrument.

     12.03.  Submission to Jurisdiction; Waiver of Jury Trial.  The parties
hereto hereby irrevocably and unconditionally:

     (i) Agree that any action, suit or proceeding by any person arising from or
relating to this Agreement or any other Transaction Document or any statement,
course or conduct, act, omission, or event occurring in connection herewith or
therewith (collectively, "Related Litigation") shall be brought only in any
State or Federal Court of competent jurisdiction sitting in Illinois and submit
to the jurisdiction of such courts;

     (ii) Waive any objection which any such party may have at anytime to the
laying of venue of any Related Litigation brought in any such court, waive any
claim that any such Related Litigation has been brought in an inconvenient
forum, and waive any right to object, with respect to any Related Litigation
brought in any such court, that such court does not have jurisdiction over such
party;

     (iii) Consent and agree to service of any summons, complaint or other
legal process in any Related Litigation by registered or certified U.S. mail,
postage prepaid, to each such party at the respective address for notices
described in Section 12.01 hereof, and consent and agree that such service shall

     (iv) Waive the right to trial by jury in any Related Litigation.

     12.04.  Specific Performance, Etc.  The parties agree that the Assets as
a going concern constitute unique property.  There is no adequate remedy at law
for the damage which Buyer might sustain for failure of Seller to consummate the
transactions contemplated by this Agreement (provided that such failure is not
as a result of any of the conditions specified in Section 7.02 hereof not being
fulfilled), and accordingly, Buyer shall be entitled, at its option, to the
remedy of specific performance to enforce the sale of the Assets by Seller to
Buyer pursuant to this Agreement.  In

addition to all other damages, to be reimbursed for its reasonable costs,
including attorneys and experts fees, incurred in connection with such action.

interpreted in accordance with, the laws of the State of Illinois.

     12.06.  Expenses.  Each party hereto will bear all expenses incurred by
it in connection with this Agreement.  Buyer will bear the cost of (i) the HSR
Act filing, including the filing fee, being made by it (ii) the Environmental
Assessments and (iii) the costs of obtaining the survey and the title Insurance
contemplated by Section 7.01 hereof.  Buyer and Seller shall each pay half of
the cost of all transfer taxes payable in connection with the transfer of the
Assets from Seller to Buyer (provided that Seller shall be responsible for all
such taxes payable in connection with any such transfer to Seller from any
Affiliate thereof or otherwise).

     12.07.  Waiver; Amendment.  Any provision of this Agreement may be (i)
amended or modified at any time (including the structure of the transactions
contemplated hereby, or any part thereof), by an agreement in writing among the
parties hereto and executed in the same manner as this Agreement or (ii) waived
by the party benefitted by the provision.

     12.08.  Entire Agreement; No Third-Party Beneficiaries; Etc.  This
Agreement, together with all Schedules attached hereto and agreements referred
to herein, represents the entire understanding of the parties hereto with
reference to the transactions contemplated hereby and supersedes any and all
other oral or written agreements heretofore made including in the Letter of
Intent dated November 17, 1995.  All terms and provisions of this Agreement
shall be binding upon and shall inure to the benefit of the parties hereto and
their respective successors and permitted assigns.  Except as otherwise
explicitly stated herein, nothing in this Agreement is intended to confer upon
any other person any rights or remedies of any nature whatsoever under or by
reason of this Agreement.

     12.11. Announcements. (a) Seller and Buyer will consult with each other as
to the form, substance and timing of the initial general notices, releases,
statements and communications with employees, suppliers, distributors and
customers and to the general public and the press relating to this Agreement,

consent of the other party, which either party may withhold in its sole
discretion; provided, however, that the foregoing shall only apply to such
announcements as are made prior to the Closing Date.

     (b) After the Closing Date, Seller and Buyer will consult with each other

exhibit will mean an article or section in, or a schedule or an exhibit to, this
Agreement, unless otherwise explicitly set forth. The titles and headings in
this Agreement are for reference purposes only and will not in any manner limit
the construction of this Agreement. For the purposes of such construction, this
Agreement will be considered as a whole.

                    STOCK RESTRICTION AND BUY-SELL AGREEMENT

Shareholders") may elect at any time to:

          (a) sell all, but not less than all, of their respective Shares,
without first having to comply with the provisions of this Agreement, provided
that:

          (i)  the Shareholders, other than the Controlling Shareholders
               ("Noncontrolling Shareholders") shall have the right to
               participate in such sale on the same terms and conditions,
               including without limitation price, as those which pertain to the
               Shares being sold by the Controlling Shareholders, and

          (ii) the Controlling Shareholders shall have the right to require that
               the Noncontrolling Shareholders sell their Shares on the same
               terms and conditions, including, without limitation price, as
               those which pertain to the Shares being sold by the Controlling
               Shareholders.

          (b) cause the Corporation to register its Shares under the Securities
Act of 1933, as amended, in a bona fide underwritten public offering (a "Public
Offering").

     2.3. Restriction on Certificates. The Corporation shall cause to be placed
on each certificate of its Shares which may now or hereafter be issued to a
Shareholder (except certificates evidencing Shares sold free of the restrictions
of this Agreement), a notice in the following form:

     "The shares of stock evidenced by this Certificate are subject to the terms
     and conditions of a certain Stock Restriction and Buy-Sell Agreement, dated
     June 6, 1996 ("Agreement"), between the Corporation and the Shareholders. A
     copy of the Agreement is on file at the offices of the Corporation,
     reference to all the terms and conditions thereof being hereby made. No
     sale or transfer of the Shares evidenced hereby may be effected, except
     pursuant to the terms and conditions of the Agreement."

     If such legend is placed on the reverse side rather than the face of any
such certificate, there shall be placed on the face of such certificate a legend
in the following form:

     "For restrictions on transfer, see notice on reverse side hereof."

                                       3

     2.4. Wrongful Transfer. Subject to Sections 2.1 and 2.2 hereof, no sale,
pledge, hypothecation, transfer, encumbrance, assignment, gift or other
disposition by a Shareholder of any of his Shares shall be effective, unless and
until: (i) he has first complied with all the provisions of this Agreement, and
(ii) such transferee shall take such Shares subject to the terms of this
Agreement, shall agree in writing to become a party to this Agreement and to be
bound by all of the terms, conditions and provisions hereof. If a Shareholder
fails to comply with this Agreement, the Corporation shall have the right to
compel such Shareholder or any transferee to transfer and deliver its Shares in
accordance with the provisions of this Agreement.

     2.5. Maintenance of S Corporation Status.

          (a) Each Shareholder agrees that he or she will take all action
necessary to permit the Corporation to retain its tax status an S Corporation
("S Corporation") under Subchapter S (Section 1361 et seq) of the Internal
Revenue Code of 1986, as amended (the "Code"), including but not limited to, the
execution and delivery of any and all consents and other documents required at
any time for the continuance of S Corporation status, or required to carry out,
effectuate, implement or exercise any and all other elections available to, or
powers exercisable by, a corporation having elected S Corporation status. Except
as otherwise specifically provided in this Agreement, the Shareholders shall not
take any action which will cause the Corporation not to be taxed as an S
Corporation.

          (b) Subject to the limitations of the Delaware General Corporation Law
("DGCL"), as long as the Corporation remains an S Corporation, the Shareholders
agree to take all actions necessary to cause the directors of the Corporation to
declare and pay to the Shareholders dividends each year in an amount not less
than all federal and state income taxes, including but not limited to estimated
tax payments, payable by the Shareholders each year with respect to the income
of the Corporation, based upon the maximum marginal federal and state individual
income tax rates applicable to any Shareholder.

          (c) Upon any transfer of the Shares permitted hereunder, the
Corporation may require arrangements reasonably satisfactory to it to assure
that any transferee shall take any and all action necessary to maintain the
election under Section 1362(a) of the Code (including without limitation, with
respect to any transfer in trust, the timely filing of an election to treat such
trust as a qualified Subchapter S Trust under Section 1361(d) of the Code).

     2.6.  Shareholder Approval for Significant Corporate Matters.
Notwithstanding any provision contained in the Certificate of Incorporation, the
By-Laws of the Corporation, any other agreement between the Shareholders and the
Corporation or under the DGCL, the Requisite Vote of the Shareholders shall be
required in connection with the following matters ("Significant Corporate
Matters"), except as expressly provided below:

          (a) the authorization of additional Shares; provided, however, that in
the event additional Shares are to be authorized in connection with a Public
Offering, then such 

                                       4

<PAGE>
 
authorization shall only require the approval of the holders of more than fifty
percent (50%) of the outstanding Shares entitled to vote;

          (b) the termination of the election to be treated as a S Corporation
under the Code.

          (c) the acquisition or divestiture of any business segment or asset
which alone, or in the aggregate, has a value in excess of $250,000, excluding,
however, the sale of substantially all of the business and/or assets of the
Corporation, which shall only require the approval of the holders of more than
fifty percent (50%) of the outstanding Shares entitled to vote;

          (d) the adoption or approval of a stock option or equity based
incentive plan for the benefit of employees of the Corporation;

          (e) the exercise by the Corporation of any call option or other right
to purchase shares under any plan described in d. above; and

          (f) any amendment to the Certificate of Incorporation or By-Laws of
the Corporation.

     All matters which under the DGCL, the Certificate of Incorporation or the
By-Laws of the Corporation require Shareholder approval but do not involve any
Significant Corporate Matters shall require the affirmative vote of the holders
of more than fifty percent (50%) of the outstanding Shares entitled to vote.

                   PURCHASE OF SHARES - RIGHT OF FIRST OFFER
                   -----------------------------------------

     3.1. Notice of Transfer. If a Shareholder ("Offering Shareholder") receives
during his lifetime a bona fide offer ("Offer") to sell or otherwise transfer
any or all of his Shares or the right to vote said Shares, or any combination
thereof ("Offered Shares") to any person or entity, the Offering Shareholder
shall give at least sixty (60) days prior written notice to the Corporation and
the Remaining Shareholders of his intention to so transfer his Shares (the
"Notice"). The Notice shall state (i) the number of Offered Shares; (ii) the
name, business and residence address of the proposed transferee (the
"Transferee"); (iii) whether or not the transfer is for valuable consideration
and, if so, the consideration (the "Offered Price"); (iv) the date upon which
the proposed transfer to the Transferee is to be consummated; and (v) all other
material terms of the proposed transfer. A copy of any written agreement
(whether executed or not) evidencing the Offer shall be attached to the Notice.

                                       5

<PAGE>
 
     3.2. Rights of First Offer. From and after the date of the Notice ("Notice
Date"), the Corporation and the Remaining Shareholders shall have options to
purchase the Offered Shares, upon the terms set forth in Section 3.3 hereof,
exercisable in the order of priority and within the time periods set forth
below:

          (a) Within thirty-five (35) days after the Notice Date (the
"Corporation's Option Period"), the Corporation shall have the option to acquire
all or any portion of the Offered Shares (the "Corporation's Option"). The
Corporation shall exercise the Corporation's Option, if at all, by giving
written notice to that effect to the Offering Shareholder and the Remaining
Shareholders within the Corporation's Option Period.

          (b) Within twenty-five (25) days following the first to occur of (i)
the expiration of the Corporation's Option Period without the Corporation
exercising its option or (ii) the Corporation's written notice to the Offering
Shareholder and the Remaining Shareholders that it will not purchase any or all
of the Offered Shares (the "Remaining Shareholders' Option Period"), the
Remaining Shareholders shall have the option to acquire all of the Offered
Shares not being purchased by the Corporation (the "Remaining Shareholders'
Option"). In the event that one or more of the Remaining Shareholders elects to
purchase the Offering Shareholder's Shares, then unless otherwise agreed, each
electing Remaining Shareholder must purchase that percentage of the Shares
offered by the Offering Shareholder as is equal to his proportionate ownership
of all of the electing Remaining Shareholders' then respective Shares. The
Remaining Shareholders shall exercise the Remaining Shareholders' Option, if at
all, by giving written notice to that effect to the Corporation and the Offering
Shareholder within the Remaining Shareholders' Option Period.

     The exercise of the Corporation's Option and/or the Remaining Shareholders'
Option must, in the aggregate, include all of the Offered Shares or the exercise
of such option(s) shall be null and void.

     3.3. Purchase Price and Terms. In the event the Corporation's Option and/or
the Remaining Shareholders' Option is exercised, the party(ies) exercising such
option(s) shall purchase the Offered Shares at the lower of (i) the Offered
Price or (ii) the Purchase Price (as hereinafter defined), upon the same terms
and conditions provided in the Notice. The Closing of such purchase shall occur
in the manner described in Section 7.2(a) hereof.

     3.4. Failure to Exercise the Corporation's and Remaining Shareholders'
Rights of First Offer Options. Subject to the terms of Section 3.5 hereof, if
the Corporation and/or the Remaining Shareholders fail to exercise their
respective Options in accordance with Section 3.2 hereof to purchase in the
aggregate all of the Offered Shares, the Offered Shares may be transferred to
the Transferee as provided in the Notice. The effectiveness of such transfer is
conditioned upon the Transferee agreeing in writing to be a party to this
Agreement and to be bound by all of the terms, conditions and provisions hereof.
If the transfer does not occur in accordance with the terms disclosed in the
Notice, such transfer shall be automatically null and void without any further
action being required on the part of the Corporation or the Remaining

                                       6

<PAGE>
 
Shareholders, and any attempt to transfer the Offered Shares thereafter without
first complying with the terms of this Article 3 shall be deemed a wrongful
transfer within the meaning of Section 2.4 hereof.

                              ------------------

     4.1. Purchase Upon Death of Shareholder. Upon the death of a Shareholder
("Decedent"), all of the Shares owned by the Decedent (the "Decedent's Shares"),
after giving effect to the rights and obligation of the Remaining Shareholders
to purchase the Decedent's Shares, as set forth in the Cross-Purchase Agreement,
shall be purchased by the Corporation from the Decedent's legal representative
(the "Representative") at the price and on the terms set forth in Articles 5, 6,
and 7 hereof.

     4.2. Put and Call Options in the Event of Permanent Disability. Upon a
Shareholder (the "Disabled Shareholder") becoming Permanently Disabled (as
hereinafter defined), the Remaining Shareholders shall have an option to
purchase (the "Call Option") all of the Shares owned by the Disabled Shareholder
or the Disabled Shareholder's Legal Representative for a period of ninety (90)
days following the Effective Date of Permanent Disability (as defined below) at
the price and on the terms set forth in Articles 5, 6 and 7 hereof, which option
shall be exercisable by the Remaining Shareholders within the aforesaid
Remaining Shareholders' option period upon written notice to the Disabled
Shareholder or the Disabled Shareholder's Legal Representative and the
Corporation. In the event that more than one of the Remaining Shareholders
elects to purchase the Disabled Shareholder's or the Disabled Shareholder's
Legal Representative's Shares, then unless otherwise agreed by the Remaining
Shareholders, each electing Remaining Shareholder must purchase only that
percentage of such Shareholder's Shares as is equal to his proportionate
ownership of all of the electing Remaining Shareholders' then respective Shares.
If the Remaining Shareholders fail to exercise such option or indicate a desire
to purchase only a portion of the Shares available for purchase, (i) the
Corporation shall have a Call Option regarding, and (ii) the Disabled
Shareholder or the Disabled Shareholder's Legal Representative shall have the
option to cause the Corporation to purchase (the "Put Option"), such Shares as
the Remaining Shareholders have elected not to purchase for a period of nine (9)
months following termination of the Remaining Shareholders' option period
described in this Section 4.2 at the price and on the terms set forth in
Articles 5, 6 and 7 hereof, which options shall be exercisable at any time
within the aforesaid option period upon written notice to the Disabled
Shareholder or the Disabled Shareholder's Legal Representative and the
Corporation, as the case may be. Notwithstanding the foregoing, the Put Option
shall not be exercisable by the Disabled Shareholder if he is deemed Permanently
Disabled by reason of his failure to submit to an examination pursuant to
Section 4.3(b) hereof.

                                       7

<PAGE>
 
          In the event the Disabled Shareholder or the Disabled Shareholder's
Legal Representative, as the case may be, does not exercise the Put Option and
the Remaining Shareholders and/or the Corporation does not exercise the Call
Option, the Disabled Shareholder or the Disabled Shareholder's Legal
Representative, as the case may be, shall hold the Disabled Shareholder's Shares
not so purchased subject to the terms, conditions and provisions of this
Agreement.

     4.3. Definition of Permanent Disability. A Shareholder shall be deemed to 
be "Permanently Disabled" upon the first to occur of the following events:

          (a) if by reason of injury, sickness or other incapacity he is unable,
for a period of six (6) consecutive months or for six (6) months during any nine
(9) consecutive month period, to discharge his regular duties and
responsibilities as an employee, officer and/or director of the Corporation. If
the parties shall at any time be unable to agree on whether a Shareholder is or
has been so disabled, the Corporation and the Shareholder shall promptly and
jointly appoint a medical doctor or if they are unable to so agree, they shall
each promptly appoint a medical doctor to make such determination, and the
collective decision of such medical doctors shall be binding on all parties
hereto. If such doctors are unable to agree, they shall promptly appoint a third
medical doctor to make such determination, and the decision of such third
medical doctor shall be binding on all parties hereto; or

          (b) the failure or refusal of a Shareholder to submit to any
examination or to appoint a medical doctor pursuant to subsection (a) of this
Section 4.3 within sixty (60) days after the date on which the Shareholder
receives a notice from the Remaining Shareholders to do so; or

          (c) the adjudication of such Shareholder as an incompetent or a
disabled person by a court of competent jurisdiction.

     4.4 Definition of Effective Date of Permanent Disability. If a Shareholder
is deemed to be Permanently Disabled pursuant to Section 4.3 hereof, then the
"Effective Date of Permanent Disability" shall be the first to occur of the
following:

          (a) the date upon which the examining doctor(s) shall determine that
the Shareholder is Permanently Disabled; or

          (b) the sixtieth (60th) day immediately succeeding the day on which a
Shareholder receives a notice from the Corporation to submit to an examination
pursuant to Section 4.3(a) hereof, if the Shareholder fails or refuses to submit
to such examination or fails or refuses to appoint a medical doctor; or

          (c) the sixtieth (60th) day immediately succeeding the date of the
adjudication described in Section 4.3(c) hereof unless prior to the expiration
of such period the adjudication has been reversed; or

                                       8

<PAGE>
 
          (d) the first day of the seventh (7th) consecutive month or the first
day of the seventh (7th) month during any nine (9) consecutive month period of
the Shareholder's inability to perform his regular duties and responsibilities
as an employee, officer and/or director of the Corporation.

     4.5. Put and Call Option in Event of Termination of Employment of
Shareholder. If a Shareholder's employment terminates (the "Terminating
Shareholder") other than for reason of his death or his becoming Permanently
Disabled, including without limitation if he is terminated for Cause (as defined
below), the Remaining Shareholders shall have a Call Option to purchase all of
the Shares owned by the Terminating Shareholder for a period of ninety (90) days
following cessation of employment at the price and on the terms set forth in
Articles 5, 6 and 7 hereof, which option shall be exercisable by the Remaining
Shareholders within the aforesaid Shareholders' option period upon written
notice to the Terminating Shareholder and the Corporation. In the event that
more than one of the Remaining Shareholders elects to purchase the Terminating
Shareholder's Shares, then unless otherwise agreed by the Remaining
Shareholders, each electing Remaining Shareholder must purchase only that
percentage of such Shareholder's Shares as is equal to his proportionate
ownership of all of the electing Remaining Shareholders' then respective Shares.
If the Remaining Shareholders fail to exercise such option or indicate a desire
to purchase only a portion of the Shares available for purchase, the Corporation
shall have a Call Option and the Terminating Shareholder shall have a Put Option
for such Shares as the Remaining Shareholders have elected not to purchase for a
period of nine (9) months following termination of the Remaining Shareholders'
option period described in this Section 4.5 at the price and on the terms set
forth in Articles 5, 6 and 7 hereof, which option shall be exercisable by the
Corporation or the Terminating Shareholder, as the case may be, at any time
within the aforesaid option period upon written notice to the Terminating
Shareholder or the Corporation, as the case may be.

          In the event the Terminating Shareholder does not exercise the Put
Option and the Remaining Shareholders and/or the Corporation does not exercise
the Call Option, the Terminating Shareholder shall hold his Shares not so
purchased subject to the terms, conditions and provisions of this Agreement.

     4.6. Definition of Cause. As used herein "Cause" shall mean: (i) commission
of any dishonest act by a Shareholder in connection with his or her employment
by the Corporation or any act of willful misconduct which has affected or can be
reasonably expected to affect the business or reputation of the Corporation in a
materially adverse manner; (ii) diversion of any material corporate opportunity
of the Corporation for the Shareholder's direct or indirect benefit; or (iii)
commission by the Shareholder of any wrongful act which constitutes cause for
dismissal of a corporate officer or employee under applicable law.
Notwithstanding the previous sentence, if "Cause" is defined in the Terminating
Shareholder's Employment Agreement, the definition set forth in such Employment
Agreement shall apply for purposes of this Agreement.

                      DETERMINATION OF THE PURCHASE PRICE
                      -----------------------------------

     5.1. Purchase Price. The parties hereto recognize the problems relative to
determining the value of the Corporation. As a result, the parties hereto agree
that subject to the terms of Section 5.5 hereof, the purchase price ("Purchase
Price") for each Share to be purchased pursuant to Articles 3 or 4 hereof shall
be the greatest of the following amounts:

          (i) Six and 34/100 Dollars ($6.34) per Share;

          (ii) two (2) times the Book Value (as defined below) of the
     Corporation divided by the total number of Shares outstanding as of the
     date of the Decedent's death; and

          (iii) an amount equal to: (a) five (5) times the Corporation's EBITDA
     (as defined below), minus (b) the principal balance of the Corporation's
     interest bearing debt as of the date of the Decedent's death, divided by
     (c) the total number of Shares outstanding as of the date of the Decedent's
     death;

The Purchase Price determined in the manner set forth above shall be conclusive
and binding on the parties hereto.

     5.2. Book Value. As used herein, the term "Book Value" of the Corporation
means the total Shareholder's equity as reflected on the Corporation's balance
sheet as of the last day of the Corporation's fiscal year immediately preceding
the date of the Decedent's death, determined by the certified public accounting
firm regularly engaged by the Corporation ("Public Accountants") in accordance
with generally accepted accounting principles applied on a basis consistent with
that of prior years and using the FIFO method of accounting for inventories. The
Book Value when certified in writing by the Public Accountants shall be binding
and conclusive on the Decedent's estate, the Representative and all other
parties concerned.

     5.3. EBITDA. As used herein, the term "EBITDA" shall mean an amount equal
to the average net income of the Corporation for the Fiscal Period (as defined
below) (i) using the FIFO method of accounting for inventories; and (ii) before
deducting interest, income taxes, depreciation and amortization. The term
"Fiscal Period" shall mean (y) if the event (the "Event") which triggers the
purchase and sale hereunder occurs during the first eight (8) months of any
given fiscal year of the Corporation, the three (3) consecutive fiscal years of
the Corporation immediately preceding the fiscal year in which the Event occurs,
and (z) if the Event occurs during the last four (4) months of any given fiscal
year of the Corporation, the three (3) consecutive fiscal years of the
Corporation ending with the fiscal year in which the Event occurs.

     5.4 Changes in EBITDA Multiplier. On or about each anniversary of the date
hereof, or at such other time as is agreeable to them, the Shareholders and the
Corporation shall review

                                      10

<PAGE>
 
the multiplier stated in Section 5.1(iii) hereof to determine whether or not
such multiplier should be amended upon the Requisite Vote of the Shareholders
and agreement by the Corporation, it being the intention of the parties that the
formula accurately reflects the fair value of the Corporation based upon all
relevant facts and circumstances at the time such matter is being considered.

     5.5. Purchase Price of Shares in Event of Termination of Shareholder for
Cause. The Purchase Price to be paid for the Shares to be purchased upon the
termination of a Shareholder for Cause (as defined in Section 4.6 hereof) shall
be an amount per Share equal to the lesser of the Purchase Price determined in
accordance with Section 5.1(i), (ii) or (iii) hereof.

                PAYMENT OF THE PURCHASE PRICE AND OTHER MATTERS
                -----------------------------------------------

     6.1. Payment. The Purchase Price for the Shares purchased hereunder shall
be paid in full in cash at the closing, except that at the option of each
purchasing party, up to sixty percent (60%) of the Purchase Price may be
deferred as provided herein, provided that at least forty (40%) of the Purchase
Price is paid in cash at closing. Notwithstanding the foregoing, in the event
the selling Shareholder is someone other than Sloan, the amount of cash to be
paid to him at the closing shall not be less than the amount originally paid by
such Shareholder for his Shares being sold, which for Andrade, Funk and Buffett
is Six and 34/100 Dollars ($6.34) per Share.

     6.2. Promissory Note. The deferred portion of the Purchase Price shall be
evidenced by a promissory note ("Note") of the purchasing party made payable to
the order of the selling party. The Note shall be in the form of Exhibit "A"
attached hereto and shall be dated as of the closing. Except as otherwise set
forth below, the principal balance shall be paid over a time not exceeding sixty
(60) months and each installment of the principal balance shall include
interest, accruing from the date of the Note, at a rate announced from time to
time by the LaSalle National Bank as its prime rate (the "Interest Rate").

     6.3 Collateral. The Note shall be secured by a pledge of all of the Shares
being purchased by that purchasing party. Any and all documents reasonably
necessary for purposes of perfecting a security interest in all of the purchased
Shares shall be executed by the purchaser including a pledge agreement
containing, among other provisions, a third party escrow for the Shares, which
pledge agreement shall be subordinated to the LaSalle Pledge Agreement and the
Sloan Pledge Agreements. Unless and until an Event of Default (as defined in the
Note) occurs, the purchaser of the Shares shall have all the rights of the owner
thereof, including without limitation the right to vote and the right to receive
dividends and other distributions. Following an Event of Default, the pledgee of
the Shares shall have all the rights of the owner thereof, provided that any
dividends or distributions made pursuant to Section 2.5(b) of this Agreement
with respect to the fiscal year in which the Event of Default occurs shall be
allocated among the

                                      11

<PAGE>
 
purchaser and the pledgee of the Shares in the same proportion as the tax
liability with respect to the income of the Corporation is allocated among them.

     6.4.  Guaranteed Indebtedness.  If at the time of a purchase of Shares
pursuant to Article 4 hereof, the Corporation has outstanding indebtedness which
is personally guaranteed by certain of the Shareholders ("Guaranteed Debt") (it
being understood by the Shareholders that Buffett shall not at any time
personally guarantee any such indebtedness), each of the Remaining Shareholders
who has personally guaranteed such indebtedness agrees to use his good faith
efforts to obtain the release of the selling Shareholder's personal guaranty of
the Guaranteed Debt, provided that (i) such Remaining Shareholders shall not be
required to offer a pledge of his residence or his spouse's guaranty in order to
secure such release, and (ii) such Remaining Shareholders' actual ability to
secure such release shall not be a condition of closing the sale and purchase
under Article 4 hereof. Notwithstanding the foregoing, the Remaining
Shareholders shall have no duty or obligation to attempt to obtain the release
of a selling Shareholder who was terminated by the Corporation for Cause.

                                 -------------

     9.1. Piggyback Registration Rights. The Corporation agrees that at any time
during the term of this Agreement, if the Corporation shall seek a Public
Offering, each Shareholder shall be notified and shall be entitled to elect to
have included in such proposed registration, without cost or expense, such
number of Shares as the underwriter for the offering shall permit; provided,
however, that in the event the underwriter shall permit less than all of the
Shares to be registered the number of shares included in such registration shall
be reduced on a pro rata basis among the Shareholders (the "Piggy-Back Rights").
In the event of such a proposed registration, the Corporation shall furnish the
Shareholders with no less than thirty (30) days written notice prior to the
proposed filing of the registration statement. Such notice shall continue to be
given by the Corporation to such Shareholders for each proposed registration by
the Corporation until such time as all of the Shares have been registered. Such
Shareholders shall exercise their Piggy-Back Rights by giving written notice
within twenty (20) days of the receipt of the Corporation's notice of intention
to file a registration statement.

     9.2. Replacement of Chief Executive Officer Upon the Death of Sloan. In the
event of the death of Sloan at a time when Sloan shall be serving as Chief
Executive Officer, the person holding the office of President at such time,
shall also hold the office and assume the duties of Chief Executive Officer
until the next election of officers of the Corporation.

     9.3. Board of Directors Deadlock. In the event of a deadlock of the Board 
of Directors, the deadlock shall be resolved by the Shareholder holding greater
than fifty (50%) percent of the outstanding Shares entitled to vote; provided,
however, that in the event no Shareholder holds such percentage, then the
deadlock shall be resolved by submitting the issue on which the Board is
deadlocked to a vote of the holders of Shares entitled to vote. In such event,
each Shareholder agrees to vote his Shares in the same way as the Shareholder
holding the largest percentage of Shares entitled to vote.

     9.4. Termination of Employment; Reduction in Salary of a Shareholder-
Employee.

          (a) In order to terminate the employment of any Shareholder either (i)
for Cause, or (ii) as a result of a disability, the Board of Directors must act
by the unanimous vote of all Directors other than the Director who is the
subject of the vote.  In all other instances, the Requisite Vote of the
Shareholders shall be required in order to terminate the employment of any
Shareholder.

          (b) In no event may the annual salary of any Shareholder who is also
an employee of the Corporation be reduced below the base salary stated in that
Shareholder's Employment Agreement with the Corporation, without such
Shareholder's express written consent.

the aggregate, exceed the budgeted amount for capital expenditures for that

          (b) entering into operating leases in any given fiscal year which, in

of an officer who is also a Shareholder;

          (d) declaration of a stock or cash dividend;

          (e) exercise of any Call Option or other right of purchase under this
Agreement;

          (f) incurring, guaranteeing or otherwise becoming liable for
indebtedness for borrowed money in an amount in excess of $500,000, or any
action to prepay any existing indebtedness by an amount in excess of $500,000;

          (g) the determination to change the Corporation's independent auditing
firm; and

          (h) the decision to employ any person or terminate the employment of
any employee of the Corporation having an annual salary of greater than
$85,000.00.

     9.6. Board of Directors. The Board of Directors of the Corporation shall
consist of four (4) persons. So long as each of Sloan, Andrade, Funk and Buffett
is a Shareholder, he shall serve on the Board of Directors. The vacancy
resulting from the death, resignation, or removal of a director shall be filled
by the unanimous decision of the directors then in office. Any director elected
to fill a vacancy shall have the same remaining term as that of his predecessor.
At the next election, the position shall be filled by the unanimous decision of
the Shareholders and until such decision is reached, that Board seat shall
remain vacant.

     9.7. Effect of Improper Transfer. Except as otherwise permitted under the
Cross Purchase Agreement or the Contribution Agreement, if a transfer or
attempted transfer violates any provision of this Agreement or if the
transferor, after the transfer, reacquires all or any portion of the transferred
Shares, such transfers or attempted transfers shall be null and void and

                                      15

<PAGE>
 
the Shares transferred or attempted to be transferred shall remain subject to
this Agreement as if no transfer had been made.

     9.8. Voting of Shares. The Representative, Disabled Shareholder, Disabled
Shareholder's Legal Representative, Offering Shareholder or Terminating
Shareholder shall have no vote regarding any given Corporation's option to
purchase Shares under this Agreement.

conditions and covenants contained herein are the full and complete terms of the
agreement between the parties hereto regarding the subject matter hereof and
supersede any and all prior agreements by and among the Corporation and the
Shareholders concerning the ownership, sale or other disposition of the Shares.

(including without limitation reasonable attorneys' and accountants' fees, costs
and expenses) incurred in connection with the legal proceeding.

     9.18. Gender. Unless the context otherwise requires, any pronouns, wherever
used herein, shall include the corresponding masculine, feminine or neuter
pronouns and the plural shall include the singular, and vice versa.

     9.19. Headings. Article and paragraph headings are included herein solely
for convenience and shall not be construed to modify or explain any of the
substantive provisions hereof.

          2.  Section 5.1 of the Agreement is hereby amended by deleting the
     words "Decedent's death" wherever such words appear in subsection (ii) and

                             RESTRICTION ON SHARES
                             ---------------------

     2.1  Prohibition on Transfer.  Except as (i) expressly permitted herein; or
(ii) provided under a certain pledge agreement between LaSalle National Bank and
the Shareholders (the "LaSalle Pledge Agreement"), and pledge agreements between
the Shareholders and each of Larry Sloan, Thomas G. Sloan and James E. Sloan
(collectively, the "Sloan Pledge Agreements"), none of the Non-Voting
Shareholders shall at any time sell, pledge, hypothecate, transfer, encumber,
assign, give away or in any way dispose of any Shares now owned or

                                       2
<PAGE>
 
hereafter acquired by him, nor shall such Shares be transferable, voluntarily or
involuntarily, by operation of law or otherwise, except in strict compliance
with the covenants, terms and conditions set forth in this Agreement.  Any
attempt to do so in violation of this Agreement shall not be recognized by the
Corporation and shall be null and void and of no force or effect whatsoever.
The Shareholders acknowledge and agree that the rights afforded Sloan pursuant
to the terms of any documents and/or agreements pertaining to the sale of Shares
by Sloan to any given Non-Voting Shareholder shall, with respect to the Shares
acquired by such Non-Voting Shareholder from Sloan, supersede the rights and
obligations of the parties hereunder.

     2.2  Restriction on Certificates.  The Corporation shall cause to be placed
on each certificate of its Shares which may now or hereafter be issued to a Non-
Voting Shareholder (except certificates evidencing Shares sold free of the
restrictions of this Agreement), a notice in the following form:

     "The shares of stock evidenced by this Certificate are subject to the terms
     and conditions of a certain Stock Restriction and Buy-Sell Agreement, dated
     as of January 1, 1997 ("Agreement"), between the Corporation and the
     Shareholders. A copy of the Agreement is on file at the offices of the
     Corporation, reference to all the terms and conditions thereof being hereby
     made.  No sale or transfer of the Shares evidenced hereby may be effected,
     except pursuant to the terms and conditions of the Agreement."

If such legend is placed on the reverse side rather than the face of any such
certificate, there shall be placed on the face of such certificate a legend in
the following form:

     "For restrictions on transfer, see notice on reverse side hereof."

     2.3  Wrongful Transfer.  Subject to Sections 2.1, no sale, pledge,
hypothecation, transfer, encumbrance, assignment, gift or other disposition by a
Non-Voting Shareholder of any of his Shares shall be effective, unless and
until: (i) he has first complied with all the provisions of this Agreement, and
(ii) such transferee shall take such Shares subject to the terms of this
Agreement, shall agree in writing to become a party to this Agreement and to be
bound by all of the terms, conditions and provisions hereof.  If a Non-Voting
Shareholder fails to comply with this Agreement, the Voting Shareholders and/or
the Corporation shall have the right to compel such Non-Voting Shareholder or
any transferee to transfer and deliver his or its Shares in accordance with the
provisions of this Agreement.

     2.4  Maintenance of S Corporation Status.

          (a) Each Non-Voting Shareholder agrees that he will take all action
necessary to permit the Corporation to retain its tax status an S Corporation
("S Corporation") under Subchapter S (Section 1361 et seq.) of the Internal
Revenue Code of 1986, as amended (the "Code"), including but not limited to, the
execution and delivery of any and all consents and other documents required at
any time for the continuance of S Corporation status, or required to carry out,
effectuate, implement or exercise any and all other elections available to, or
powers
                                       3
<PAGE>
 
exercisable by, a corporation having elected S Corporation status. Unless and
until the Controlling Shareholders direct otherwise in writing, the Non-Voting
Shareholders shall not take any action which will cause the Corporation not to
be taxed as an S Corporation.

          (b) Subject to the limitations of the Delaware General Corporation Law
("DGCL"), as long as the Corporation remains an S Corporation, each Shareholder
agrees to take all actions necessary to cause the Board of Directors of the
Corporation to declare and pay to the Shareholders dividends each year in an
amount not less than all federal and state income taxes, including but not
limited to estimated tax payments, payable by the Shareholders each year with
respect to the income of the Corporation, based upon the maximum marginal
federal and state individual income tax rates applicable to any Shareholder.

          (c) Upon any transfer of the Shares permitted hereunder, the
Corporation may require arrangements reasonably satisfactory to it to assure
that any transferee shall take any and all action necessary to maintain the
election under Section 1362(a) of the Code.

     2.5  Take-along Rights.  The Controlling Shareholders agree that if they
sell or transfer, in the aggregate, a majority of the Voting Shares to a third
party, they will first give written notice (the "Take-along Notice") to the Non-
Voting Shareholders stating all of the material terms of the offer.  Each of the
Non-Voting Shareholders may then participate pro rata in such transfer based on
his proportionate holdings of Shares in relation to the total number of
outstanding shares (both voting and non-voting) of the common stock of the
Corporation.  If a Non-Voting Shareholder wishes to participate in such
transaction, he will give the Corporation and the Voting Shareholders written
notice within five (5) days of receipt of the Take-along Notice, and the sale
transaction will not close prior thereto.  The foregoing notwithstanding, the
provisions of this Section 2.5 shall not apply to (i) any transfers of Voting
Shares among or between the Voting Shareholders and/or their respective family
members, in trust or otherwise, either during their lifetimes or after their
deaths, and (ii) the pledge or hypothecation of Voting Shares.

     2.6  Drag-A-Long Rights.  In the event of an Approved Sale, each of the
Non-Voting Shareholders agrees to sell his Shares on the terms and conditions
approved by the Corporation's Board of Directors and/or the Controlling
Shareholders.  Each Non-Voting Shareholder will not exercise any statutory
dissenters' rights with regard to an Approved Sale and will take all necessary
and desirable actions in connection with the consummation of the Approved Sale.
The foregoing notwithstanding, the right of the Corporation and/or the
Controlling Shareholders to consummate any Approved Sale structured as a sale of
common stock is subject to the satisfaction of the condition that, upon the
consummation of the Approved Sale, each Non-Voting Shareholder will receive the
same form and amount of consideration per Share as the Voting Shareholders
receive for their Voting Shares, or if the Voting Shareholders are given an
option as to the form and amount of consideration to be received, the Non-Voting
Shareholders will be given the same option.

                   PURCHASE OF SHARES - RIGHT OF FIRST OFFER
                   -----------------------------------------

     3.1  Notice of Transfer.  If a Non-Voting Shareholder ("Offering
Shareholder") receives during his lifetime a bona fide offer ("Offer") to sell
or otherwise transfer any or all of his Shares ("Offered Shares") to any other
Non-Voting Shareholder, the Offering Shareholder shall give at least sixty (60)
days prior written notice to the Corporation and the Voting Shareholders of his
intention to so transfer his Shares (the "Notice").  The Notice shall state (i)
the number of Offered Shares; (ii) the name of the Non-Voting Shareholder who is
the proposed transferee (the "Transferee"); (iii) whether or not the transfer is
for valuable consideration and, if so, the consideration (the "Offered Price");
(iv) the date upon which the proposed transfer to the Transferee is to be
consummated; and (v) all other material terms of the proposed transfer. A copy
of any written agreement (whether executed or not) evidencing the Offer shall be
attached to the Notice.

     3.2  Rights of First Offer.  From and after the date of the Notice
("Notice Date"), the Voting Shareholders and the Corporation shall have options
to purchase the Offered Shares, upon the terms set forth in Section 3.3 hereof,
exercisable in the order of priority and within the time periods set forth
below:

          (a) Within twenty-one (21) days after the Notice Date (the "Sloan's
Option Period"), Sloan shall have the option to acquire all or any portion of
the Offered Shares ("Sloan's Option").  Sloan shall exercise Sloan's Option, if
at all, by giving written notice to that effect to the Offering Shareholder, the
other Voting Shareholders and the Corporation within Sloan's Option Period.

          (b) Within twenty one (21) days following the first to occur of (i)
the expiration of Sloan's Option Period without Sloan exercising his option or
(ii) Sloan's written notice to the Offering Shareholder, the other Voting
Shareholders and the Corporation that he will not purchase any or all of the
Offered Shares (the "Voting Shareholders' Option Period"), the Voting
Shareholders, other than Sloan, shall have the option to acquire all of the
Offered Shares not being purchased by Sloan (the "Voting Shareholders' Option").
In the event that one or more of such Voting Shareholders elects to purchase the
Offering Shareholder's Shares, then unless otherwise agreed, each electing
Voting Shareholder must purchase that percentage of the Shares offered by the
Offering Shareholder as is equal to his proportionate ownership of all of the
electing Voting Shareholders' Voting Shares.  The Voting Shareholders shall
exercise the Voting Shareholders' Option, if at all, by giving written notice to
that effect to Sloan, the Corporation and the Offering Shareholder within the
Voting Shareholders' Option Period.

          (c) Within fourteen (14) days following the first to occur of (i) the
expiration of the Voting Shareholders' Option Period without Sloan and/or the
other Voting Shareholders exercising their options; or (ii) written notice to
the Corporation that neither Sloan nor the other Voting Shareholders intend to
purchase all of the Offered Shares (the "Corporation's Option"),

                                       5
<PAGE>
 
the Corporation shall have the option to acquire all of the Offered Shares not
being purchased by Sloan or the other Voting Shareholders. The Corporation shall
exercise the Corporation's Option, if at all, by giving written notice to that
effect to the Offering Shareholder and the Voting Shareholders within the
Corporation's Option Period.

     The exercise of the aforesaid options must, in the aggregate, include all
of the Offered Shares or the exercise of such option(s) shall be null and void.

     3.3  Purchase Price and Terms.  In the event Sloan's Option, the Voting
Shareholders' Option and/or the Corporation's Option is exercised, the
party(ies) exercising such option(s) shall purchase the Offered Shares at the
lower of (i) the Offered Price or (ii) the Purchase Price (as hereinafter
defined) determined in accordance with Section 5.5 hereof, upon the same terms
and conditions provided in the Notice. The Closing of such purchase shall occur
in the mariner described in Section 7.2(a) hereof.

     3.4  Failure to Exercise Rights of First Offer Options.  If Sloan, the
Voting Shareholders and/or the Corporation fail to exercise their respective
Options in accordance with Section 3.2 hereof to purchase in the aggregate all
of the Offered Shares, the Offered Shares may be transferred to the Transferee
as provided in the Notice.  The effectiveness of such transfer is conditioned
upon the Transferee then being a Non-Voting Shareholder immediately prior to
such transfer and his reaffirming in writing his agreement to be bound by all of
the terms, conditions and provisions hereof.  If the transfer does not occur in
accordance with the terms disclosed in the Notice, such transfer shall be
automatically null and void without any further action being required on the
part of the Corporation or the Voting Shareholders, and any attempt to transfer
the Offered Shares thereafter without first complying with the terms of this
Article 3 shall be deemed a wrongful transfer within the meaning of Section 2.3
hereof.

     4.1  Purchase Upon Death, Permanent Disability or Termination of
Employment of Non-Voting Shareholder.  If a Non-Voting Shareholder dies (the
"Decedent"), becomes Permanently Disabled (as defined below) (the "Disabled
Shareholder"), or his employment by the Corporation terminates (the "Terminating
Shareholder") (a Decedent, Disabled Shareholder or Terminating Shareholder is
sometimes hereinafter referred to as a "Departed Shareholder"), the Shares owned
by the Departed Shareholder, shall be subject to the following rights and
obligations, and the Non-Voting Shareholders, for themselves and their
respective heirs, successors, representatives and assigns, agree as follows:

     (a) Within sixty (60) days following: (i) the date of the Decedent's death,
(ii) the Effective Date of Permanent Disability (as defined below) of the

portion of the Shares owned by the Departed Shareholder ("Sloan's Purchase
Option"), at the price and on the terms set forth in Articles 5, 6 and 7 hereof.
Sloan shall exercise Sloan's Purchase Option, if at all, by giving written
notice to that effect to the Departed Shareholder, the other Voting Shareholders
and the Corporation within Sloan's Purchase Option Period.

     (b) Within thirty (30) days following the first to occur of (i) the
expiration of Sloan's Purchase Option Period without Sloan exercising his option
or (ii) Sloan's written notice to the Departed Shareholder, the other Voting
Shareholders and the Corporation that he will not purchase any or all of the
Departed Shareholder's Shares (the "Voting Shareholders' Purchase Option
Period"), the Voting Shareholders, other than Sloan, shall have the option to
acquire all of the Departed Shareholder's Shares not being purchased by Sloan
(the "Voting Shareholders' Purchase Option"), at the price and on the terms set
forth in Articles 5, 6 and 7 hereof.  In the event that one or more of such
Voting Shareholders elects to purchase the Departed Shareholder's Shares, then,
unless otherwise agreed, each electing Voting Shareholder must purchase that
percentage of the Departed Shareholder's Shares as is equal to his proportionate
ownership of all of the electing Voting Shareholders' Voting Shares.  The Voting
Shareholders shall exercise the Voting Shareholders' Purchase Option, if at all,
by giving written notice to that effect to Sloan, the Corporation and the
Departed Shareholder within the Voting Shareholders' Purchase Option Period.

     (c) Subject to Section 4.2 hereof, the Corporation shall purchase, and the
Departed Shareholder or his legal representative shall sell, all of the Shares
owned by the Departed Shareholder which are not purchased by Sloan and/or the
other Voting Shareholders pursuant to Sections 4.1(a) or (b) above, at the price
and on the terms set forth in Articles 5, 6 and 7 hereof.

     (d) Notwithstanding the foregoing provisions of this paragraph 4.1 but
subject in all events, however, to the rights and obligations to sell Shares
otherwise set forth herein, any Senior Terminating Shareholder (as defined
below) who resigns prior to January 1, 2002, may irrevocably elect to defer the
purchase and sale of his Shares (due to such termination of employment), such
that with respect to determining the Purchase Price for such Senior Terminating
Shareholder's Shares, the Event (as defined in paragraph 5.1 hereof) shall be
deemed to have occurred either on January 1, 2002 or on the fifth (5th)
anniversary of the last day of such Senior Terminating Shareholder's employment
by the Corporation.  The Senior Terminating Shareholder shall give written
notice of such election to the Voting Shareholders and the Corporation within
thirty (30) days following the last day of his employment, which notice shall
express such irrevocable election and shall specify whether the Event shall be
deemed to occur on January 1, 2002 or on the fifth (5th) anniversary of the last
date of his employment. In such circumstance, Sloan's Purchase Option Period,
the Voting Shareholder's Purchase Option Period and the respective rights and
obligations of the Voting Shareholders, the Corporation and such Senior
Terminating Shareholder with respect to the purchase and sale of his Shares
shall pertain as if the date designated by such Senior Terminating Shareholder
for the Event was the last day of his employment. As used herein, the term
"Senior Terminating Shareholder" means a Terminating Shareholder who was either
(i) 62 years of age, or

                                       7

the time he first acquired Shares.

     4.2  Termination of Employment for Cause.  Notwithstanding the terms of
Section 4.1(c) above, if the Terminating Shareholder's employment by the
Corporation is terminating for Cause (as defined below), then the Corporation
shall not be obligated to purchase the Terminating Shareholder's Shares, and in
lieu of any such obligation, the Corporation shall have the option to acquire
all or any portion of the Terminating Shareholder's Shares not being purchased
by Sloan or the other Voting Shareholders pursuant to their respective options
as set forth above, on the terms set forth in Articles 5, 6 and 7 hereof. The
Corporation shall exercise such option, if at all, by giving written notice to
that effect to the Terminating Shareholder and the Voting Shareholders within
one hundred eighty (180) days following the first to occur of (i) the expiration
of Sloan's Purchase Option and the Voting Shareholders' Purchase Option without
them having exercised such options or (ii) Sloan's and the other Voting
Shareholders' written notice to the Corporation and the Terminating Shareholder
stating that they will not purchase the Terminating Shareholder's Shares. In the
event that neither Sloan, the other Voting Shareholders nor the Corporation
exercise their respective options to purchase the Shares of a Terminating
Shareholder whose employment is terminated for Cause, the Terminating
Shareholder, or his heirs, representatives, successors and assigns, shall hold
such Shares not so purchased subject to the terms, conditions and provisions of
this Agreement.

deemed to be "Permanently Disabled" upon the first to occur of the following

responsibilities as an employee and/or officer of the Corporation.  If the
parties shall at any time be unable to agree on whether a Non-Voting Shareholder
is or has been so disabled, the Corporation and the Non-Voting Shareholder shall
promptly and jointly appoint a medical doctor or if they are unable to so agree,
they shall each promptly appoint a medical doctor to make such determination,
and the collective decision of such medical doctors shall be binding on all
parties hereto.  If such doctors are unable to agree, they shall promptly
appoint a third medical doctor to make such determination, and the decision of
such third medical doctor shall be binding on all parties hereto; or

          (b) the failure or refusal of a Non-Voting Shareholder to submit to
any examination or to appoint a medical doctor pursuant to subsection (a) of
this Section 4.3 within sixty (60) days after the date on which the Non-Voting
Shareholder receives a notice from the Voting Shareholders and/or the
Corporation to do so; or

          (c) the adjudication of such Non-Voting Shareholder as an incompetent
or a disabled person by a court of competent jurisdiction.

     4.4  Definition of Effective Date of Permanent Disability.  If a Non-Voting
Shareholder is deemed to be Permanently Disabled pursuant to Section 4.3 hereof,

the Corporation to submit to an examination pursuant to Section 4.3(a) hereof,
if the Non-Voting Shareholder fails or refuses to submit to such examination or
fails or refuses to appoint a medical doctor; or

          (c) the sixtieth (60th) day immediately succeeding the date of the
adjudication described in Section 4.3(c) hereof unless prior to the expiration

the following as determined by the Board of Directors in its sole discretion:
(i) commission of any dishonest act by a Non-Voting Shareholder in connection
with his employment by the Corporation or any act of willful misconduct which

                      DETERMINATION OF THE PURCHASE PRICE
                      -----------------------------------

     5.1  Purchase Price.  The parties hereto recognize the problems relative to

          (i) Six and 34/100 Dollars ($6.34) per Share;

          (ii) two (2) times the Book Value (as defined below) of the

<PAGE>
 
     stock outstanding as of the date of the event which triggers the purchase
     and sale hereunder (the "Event"); and

     5.2  Book Value.  As used herein, the term "Book Value" of the Corporation
means the total Shareholder's equity as reflected on the Corporation's balance
sheet as of the last day of the Corporation's fiscal year immediately preceding
the Event, determined by the certified public accounting firm regularly engaged
by the Corporation ("Public Accountants") in accordance with generally accepted
accounting principles applied on a basis consistent with that of prior years and

below) (i) using the FIFO method of accounting for inventories; and (ii) before

that the formula accurately reflects the fair value of the Corporation based
upon all relevant facts and circumstances at the time such matter is being
considered.  The parties agree that such multiplier shall be changed from time

                                 -------------

     9.1  Piggyback Registration Rights.  The Corporation agrees that at any
time during the term of this Agreement, if the Corporation shall seek a Public
Offering, each Non-Voting Shareholder shall be notified and shall be entitled to
elect to have included in such proposed registration, without cost or expense,
such number of Shares as the underwriter for the offering shall permit;
provided, however, that in the event the underwriter shall permit less than all
of the Shares to be registered the number of Shares included in such
registration shall be reduced on a pro rata basis among the Non-Voting
Shareholders (the "Piggy-Back Rights").  In the event of such a proposed
registration, the Corporation shall furnish the Non-Voting Shareholders with no
less than thirty (30) days written notice prior to the proposed filing of the
registration statement.  Such notice shall continue to be given by the
Corporation to such Non-Voting Shareholders for each proposed registration by
the Corporation until such time as all of the Shares have been registered.  Such
Non-Voting Shareholders shall exercise their Piggy-Back Rights by giving written
notice within twenty (20) days of the receipt of the Corporation's notice of
intention to file a registration statement.

     9.2  Restrictive Covenants.

          (a) Each of the Non-Voting Shareholders agree that during the Non-
Voting Shareholder's employment and for a period of eighteen (18) months after
the termination of his employment for any reason whatsoever or for no reason,
whether voluntary or involuntary, the Non-Voting Shareholder will not, except on
behalf of the Corporation:

          (i) directly or indirectly, contact, solicit or direct any person,
     firm or corporation to contact or solicit, any of the Corporation's
     customers or prospective customers (as hereinafter defined) for the purpose
     of selling or attempting to sell, any products and/or services that are the
     same as or similar to the products and services provided by the Corporation
     to its customers.  In addition, each Non-Voting Shareholder will not
     disclose the identity of any such customers or prospective customers to any
     person, firm, corporation, association, or other entity for any reason or
     purpose whatsoever; and

          (ii) directly or indirectly, whether as an investor (excluding
     investments representing less than one percent (1%) of the common stock of
     a public company), lender, owner, stockholder, officer, director,
     consultant, employee, agent, salesperson or in any other capacity, whether
     part-time or full-time, become associated with any business involved in the
     design, manufacture, marketing, sale, or servicing of products then
     constituting one percent (1%) or more of the annual sales of the
     Corporation; and

          (iii)  solicit or accept if offered to him, with or without
     solicitation, on his own behalf or on behalf of any other person, the
     services of any person who is an employee of 

                                      13
<PAGE>
 
     the Corporation, nor solicit any of the Corporation's employees to
     terminate employment with the Corporation; and

          (iv) act as a consultant, advisor, officer, manager, agent, director,
     partner, independent contractor, owner, or employee for or on behalf of any
     of the Corporation's customers or prospective customers (as hereinafter
     defined), with respect to or in any way with regard to any aspect of the
     Corporation's business and/or any other business activities in which the
     Corporation engages during the term of the Non-Voting Shareholder's
     employment with the Corporation.

          (b) As used herein, "customer" shall be defined as any person, firm,
or entity that purchased any type of product and/or service from the Corporation
or is or was doing business with the Corporation within the twelve (12) month
period immediately preceding termination of the Non-Voting Shareholder's
employment; and "prospective customer" shall be defined as any person, firm, or
entity contacted or solicited by the Corporation or the Non-Voting Shareholder
(whether directly or indirectly) or who contacted the Corporation or the Non-
Voting Shareholder (whether directly or indirectly) within the twelve (12) month
period immediately preceding termination of the Non-Voting Shareholder's
employment for the purpose of having such persons, firms, or entities become a
customer of the Corporation.

          (c) Each of the Non-Voting Shareholders acknowledges and agrees that
any violation of the terms of the Confidentiality Agreement between him and the
Corporation, including without limitation such Non-Voting Shareholder's
divulging or imparting any confidential information of the Corporation to any
competitor of the Corporation or any third party, or using such confidential
information for himself, shall afford the Corporation all of the rights and
remedies set forth in paragraph 9.2(d) hereof.

          (d) It is agreed that any breach or anticipated or threatened breach
of any of the Non-Voting Shareholder's covenants contained in this paragraph 9.2
will result in irreparable harm and continuing damages to the Corporation and
its business and that the Corporation's remedy at law for any such breach or
anticipated or threatened breach will be inadequate and, accordingly, in
addition to any and all other remedies that may be available to the Corporation
at law or in equity in such event, any court of competent jurisdiction may issue
a decree of specific performance or issue a temporary and permanent injunction,
without the necessity of the Corporation posting bond or furnishing other
security and without proving special damages or irreparable injury, enjoining
and restricting the breach, or threatened breach, of any such covenant. In
addition to, and not in lieu of, the foregoing rights and remedies, the
Corporation shall be entitled to receive from the breaching Non-Voting
Shareholder an amount equal to the unpaid balance, if any, of the Purchase Price
due to the breaching Non-Voting Shareholder (as of the date such breach first
occurred) with respect to the purchase of his Share, and such amount may be set
off from any monies due such breaching Non-Voting Shareholder by the
Corporation, which amount shall constitute liquidated damages and not a penalty.
In the event the maker of the Note is someone other than the Corporation, the
breaching Non-Voting Shareholder shall be deemed to have irrevocably assigned to
the Corporation all of his right, title and interest in and to the Note,
including without limitation the balance of any and all amounts remaining unpaid

                                       14
<PAGE>
 
thereunder, and no additional amounts shall be owed to such breaching Non-Voting
Shareholder under the Note.

          (e) Anything contained in this paragraph 9.2 to the contrary
notwithstanding, a Terminating Shareholder (i) whose employment is terminated by
the Corporation at any time other than for Cause; or (ii) whose employment
terminates (including without limitation, upon his resignation) on or after
January 1, 2002 other than for Cause, shall have the right and option to be free
of the restrictive covenants imposed by paragraph 9.2(a) of this Agreement
following his employment, provided such Terminating Shareholder elects to
receive, in lieu of the Purchase Price determined in accordance with paragraph
5.1 hereof, an amount for his Shares equal to the amount the Terminating
Shareholder paid to acquire such Shares.  The Terminating Shareholder shall
irrevocably make such election by giving written notice thereof to the Voting
Shareholders and the Corporation within thirty (30) days following the last date
of such Terminating Shareholder's employment, which notice must expressly state
that the Terminating Shareholder has irrevocably elected to receive an amount
for his Shares equal to the amount such Terminating Shareholder paid to acquire
same in lieu of the Purchase Price determined in accordance with paragraph 5.1
of this Agreement.  In such event, such Terminating Shareholder shall be deemed
to be released from the restrictive covenants set forth in paragraph 9.2 hereof,
provided that such Terminating Shareholder proceeds to sell his Shares in strict
accordance with the other terms of this Agreement.  The Non-Voting Shareholders
acknowledge that the foregoing right and option shall not be available to any
Non-Voting Shareholder whose employment terminates (i) due to his resignation
prior to January 1, 2002, or (ii) at any time for Cause.

     9.3  Effect of Improper Transfer.  If a transfer or attempted transfer
violates any provision of this Agreement or if the transferor, after the
transfer, reacquires all or any portion of the transferred Shares, such
transfers or attempted transfers shall be null and void and the Shares
transferred or attempted to be transferred shall remain subject to this
Agreement as if no transfer had been made.

     9.4  Entire Agreement.  The terms, conditions and covenants contained
herein are the full and complete terms of the agreement between the parties
hereto regarding the subject matter hereof and supersede any and all prior
agreements by and among the Corporation and the Shareholders concerning the
ownership, sale or other disposition of the Shares. No alterations, amendments
or modifications of such terms shall be binding on the parties hereto unless
reduced to writing and approved by the Board of Directors of the Corporation.

     9.5  Binding Effect.  This Agreement shall be binding not only upon the
parties hereto, but upon their respective heirs, legal representatives,
successors and assigns.  All persons bound hereby shall execute such instruments
and perform such acts as may be reasonably necessary or desirable to effectuate
the terms and provisions of this Agreement.

     9.6  Adoption by Corporation.  The Voting Shareholders will cause the Board
of Directors to adopt appropriate minutes and resolutions recognizing,
confirming, ratifying and adopting the terms of this Agreement and any
amendments to the By-Laws consistent with the provisions herein.

     9.7  Reference in Will.  Each Non-Voting Shareholder shall make reference
to this Agreement in any Will or Codicil that he may hereafter execute and shall
direct the executor therein to comply with all of its terms and provisions.

shall be deemed adequately given only if in writing and personally delivered,
sent by first class registered or certified mail, postage prepaid, return
receipt requested; sent by telefacsimile, provided a hard copy is mailed on that
date to the party for whom such notices are intended or sent by other means at
least as fast and reliable as first class mail.  A written notice shall be

it shall be delivered to the address required by this Agreement; (ii) the date
delivery shall have been refused at the address required by this Agreement;
(iii) with respect to notices sent by mail, the date as of which the postal
service shall have indicated such notice to be undelivered at the address
required by this Agreement, or (iv) with respect to a telefacsimile, the date on

Agreement, or which any party desires to give to the other, shall be addressed

or to such other address as the person to whom notice is to be given may have
furnished to the other in writing in accordance herewith.  A communication given
by any other means shall be deemed duly given when actually received by the
addressee.

     9.9  Specific Performance.  The Shares cannot be readily purchased or sold
in the open market, and for that reason, among others, the parties will be
irreparably damaged in the event that this Agreement is not specifically
enforced.  Should any dispute arise concerning whether a proposed sale or
disposition of the Shares would violate this Agreement, the parties agree that
an injunction may be issued restraining any sale or disposition pending the
determination of such controversy.  In the event of any controversy concerning
the right or obligation to purchase or sell any of the Shares, such right or
obligation shall be enforceable in a court of equity by a decree of specific
performance.  Such remedy shall, however, be cumulative and not exclusive, and
shall be in addition to any other remedy which the parties may have at law, in
equity or otherwise.

     9.10 Construction of Terms.  Unless otherwise specifically provided, a
reference to a particular "section", "Section", or "Article" shall mean the
section, Section, or Article in this Agreement.

     9.11 Governing Law.  This Agreement shall be interpreted, governed and
construed in all respects by the internal laws of the State of Illinois, and any
action commenced to enforce any of the provisions hereof shall have as its venue
Christian County, Illinois.

     9.12 Payment of Legal Costs and Expenses.  In the event any action is
commenced to challenge or enforce the terms and provisions hereof, the party who
is successful in such action based upon a final, unappealable court order, shall
be reimbursed by the unsuccessful party for his fee, costs and expenses
(including without limitation reasonable attorneys' and accountants' fees, costs
and expenses) incurred in connection with the legal proceeding.

     9.13 Gender.  Unless the context otherwise requires, any pronouns, wherever
used herein, shall include the corresponding masculine, feminine or neuter
pronouns and the plural shall include the singular, and vice versa.

     9.14 Headings.  Article and paragraph headings are included herein solely
for convenience and shall not be construed to modify or explain any of the
substantive provisions hereof.

                                       17
<PAGE>
 
     9.15 Binding Effect.  This Agreement is binding upon and inures to the
benefit of the Corporation, its successors, transferees and assigns and to the
Shareholders and their respective heirs, personal representatives, successors,
permitted transferees and permitted assigns.  Wherever used in this Agreement,
Non-Voting Shareholder shall refer to the Non-Voting Shareholders originally
named above and any persons who subsequently acquire the Shares for so long as
they shall have any interest in the Shares, and thereafter to his or their
respective heirs, personal representatives, successors, transferees and assigns.

     9.16 Counterparts.  This Agreement may be executed and delivered in two or
more substantially identical counterparts, each of which shall be an original
document as to the person or persons signing it and all of which together shall
constitute a single binding agreement.

     9.17 Invalid Provision.  If any provision of this Agreement is finally
determined by any court of competent jurisdiction to be effective only if said
provision is modified to limit its duration, area, scope, or applicability and
if such determination is upheld on appeal or no appeal from such determination
is taken, then the parties hereto agree that they shall amend and modify such
provisions to restrict the duration, area, scope, or applicability thereof to
the minimum extent required to make such provision enforceable, and they further
hereby consent to the entry by a court of an order to so restrict such
provision.  If any provision of this Agreement shall be held invalid, the
remainder of this Agreement shall continue in full force and effect.

     9.18 No Right to Continued Employment.  Nothing contained herein or by
virtue of the ownership of Shares by any or all of the Non-Voting Shareholders
shall create, or be deemed to create, any right of employment in any Non-Voting
Shareholder, limit or restrict the Corporation's or any given Non-Voting
Shareholder's right to terminate such Non-Voting Shareholder's employment or
evidence any agreement or understanding that any given Non-Voting Shareholder
will remain employed by the Corporation for any particular length of time.

Ladies and Gentlemen:

     Upon the terms and subject to the conditions of the Exchange Offer, the
undersigned hereby tenders to the Company the above described principal amount
of Old Notes in exchange for an identical principal amount of New Notes.
Subject to, and effective upon, the acceptance for exchange of the Old Notes
tendered herewith, the undersigned hereby exchanges, assigns and transfers to or
upon the order of the Company all right, title and interest in and to such Old
Notes as are being tendered herewith, including all rights to accrued and unpaid
interest thereon as of the Expiration Date.  The undersigned hereby irrevocably
constitutes and appoints the Exchange Agent as its agent and attorney-in-fact
(with full knowledge that the Exchange Agent is also acting as agent of the
Company in connection with the Exchange Offer) to cause the Old Notes to be
assigned, transferred and exchanged.

     THE UNDERSIGNED HEREBY REPRESENTS AND WARRANTS THAT THE UNDERSIGNED HAS
FULL POWER AND AUTHORITY TO TENDER, EXCHANGE, ASSIGN AND TRANSFER THE OLD NOTES
TENDERED HEREBY AND TO ACQUIRE NEW NOTES ISSUABLE UPON THE EXCHANGE OF SUCH
TENDERED OLD NOTES, AND THAT, WHEN THE OLD NOTES ARE ACCEPTED FOR EXCHANGE, THE
COMPANY WILL ACQUIRE GOOD, MARKETABLE AND UNENCUMBERED TITLE THERETO, FREE AND
CLEAR OF ALL LIENS, RESTRICTIONS, CHARGES AND ENCUMBRANCES, AND THAT THE OLD
NOTES TENDERED HEREBY ARE NOT SUBJECT TO ANY ADVERSE CLAIMS OR PROXIES.  THE
UNDERSIGNED WILL, UPON REQUEST, EXECUTE AND DELIVER ANY ADDITIONAL DOCUMENTS
DEEMED BY THE COMPANY OR THE EXCHANGE AGENT TO BE NECESSARY OR DESIRABLE TO
COMPLETE THE EXCHANGE, ASSIGNMENT AND TRANSFER OF THE OLD NOTES TENDERED HEREBY.
THE UNDERSIGNED HAS READ AND AGREES TO ALL OF THE TERMS OF THE EXCHANGE OFFER.

     The undersigned understands that tenders of Old Notes pursuant to any one
of the procedures described in "The Exchange Offer--Procedures for Tendering Old
Notes" in the Prospectus and in the instructions herein will, upon the Company's
acceptance for exchange of such tendered Old Notes, constitute a binding
agreement between the undersigned and the Company upon the terms and subject to
the conditions of the Exchange Offer.

     The undersigned also warrants that it will, upon request, execute and
deliver any additional documents deemed by the Exchange Agent or the Company to
be necessary or desirable to complete the exchange, assignment and transfer of
tendered Old Notes or transfer ownership of such Old Notes on the account books
maintained by a book-entry transfer facility.  The undersigned further agrees
that acceptance of any tendered Old Notes by the Company and the issuance of New
Notes in exchange therefor shall constitute performance in full by the Company
of its obligations under the Registration Rights Agreement and that the Company
shall have no further obligations or liabilities thereunder for the registration
of the Old Notes or the New Notes.

     The Exchange Offer is not conditioned upon any principal amount of Old
Notes being tendered for exchange.  However, the Exchange Offer is subject to
certain conditions set forth in the Prospectus under the caption "The Exchange
Offer--Conditions."  The undersigned recognizes that as a result of these
conditions (which may be waived, in whole or in part, by the Company), as more
particularly set forth in the Prospectus, the Company may not be required to
exchange any of the Old Notes tendered hereby and, in such event, the Old Notes
not exchanged will be returned to the undersigned at the address shown below the
signature of the undersigned.

     The name(s) and addressee(s) of the registered holder(s) of the Old Notes
tendered hereby should be printed above, if they are not already set forth
above, as they appear on the Certificates representing such Old Notes.  The
Certificate number(s) and the Old Notes that the undersigned wishes to tender
should be indicated in the appropriate boxes above.

     The undersigned acknowledges that this Exchange Offer is being made in
reliance on the position of the staff of the Security and Exchange Commission
(the "Commission") as set forth in certain interpretive letters addressed to
third parties in other transactions substantially similar to the Exchange Offer,
which lead the Company to believe that New Notes issued pursuant to the Exchange
Offer to a holder in exchange for Old Notes may be offered for resale, resold
and otherwise transferred by a holder (other than (i) a broker-dealer who
purchased Old

                                      -4-
<PAGE>
 
Notes directly from the Company for resale pursuant to Rule 144A or any other
available exemption under the Securities Act, (ii) an "affiliate" of the Company
within the meaning of Rule 405 under the Securities Act, or (iii) a broker-
dealer who acquired the Old Securities as a result of market-making or other
trading activities) without further compliance with the registration and
prospectus delivery provisions of the Securities Act, provided, that such holder
is acquiring the New Notes in the ordinary course of business and is not
participating, and has no arrangement or understanding with any person to
participate, in the distribution of the New Notes.  Accordingly, the undersigned
represents that (i) it is not an "affiliate" of the Company as defined in Rule
405 of the Securities Act, (ii) it is not a broker-dealer that acquired Old
Notes directly from the Company in order to resell them pursuant to Rule 144A of
the Securities Act or any other available exemption under the Securities Act,
(iii) it will acquire the New Notes in the ordinary course of business and (iv)
it is not participating, and has no arrangement or understanding with any person
to participate, in the distribution of the New Notes. The undersigned
acknowledges that if it is unable to make these representations to the Company,
it will not be able to rely on the interpretations of the staff of the
Commission described above and therefore will be required to comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with any sale or other transfer of such Old Notes unless such sale is
made pursuant to an exemption from such requirements. If the undersigned is a
broker-dealer that will receive New Notes for its own account in exchange for
Old Notes, it represents that it acquired the Old Notes for its own account as a
result of market-making activities or other trading activities and acknowledges
that it will deliver a prospectus meeting the requirements of the Securities Act
in connection with any resale of such New Notes; however, by so acknowledging
and by delivering a prospectus, the undersigned will not be deemed to admit that
it is an "underwriter" within the meaning of Section 2(11) of the Securities
Act. Failure to comply with any of the above-mentioned requirements could result
in the undersigned or any such other person incurring liability under the
Securities Act for which such persons are not indemnified by the Company.

     Unless otherwise indicated in the box entitled "Special Exchange
Instruction" or the box entitled "Special Delivery Instructions" in this Letter
of Transmittal, certificates for all New Notes delivered in exchange for
tendered Old Notes, and any Old Notes delivered herewith but not exchanged, will
be registered in the name of the undersigned and shall be delivered to the
undersigned at the address shown below the signature of the undersigned. If a
New Note is to be issued to a person other than the person(s) signing this
Letter of Transmittal, or if the New Note is to be mailed to someone other than
the person(s) signing this Letter of Transmittal or to the person(s) signing
this Letter of Transmittal at an address different than the address shown on
this letter of Transmittal, the appropriate boxes of this Letter of Transmittal
should be completed.  If Old Notes are surrendered by holder(s) that have
completed either the box entitled "Special Exchange Instructions" or the box
entitled "Special Delivery Instructions" in this Letter of Transmittal,
signature(s) on this Letter of Transmittal must be guaranteed by an Eligible
Institution (as defined in Instruction 2).

     All authority herein conferred or agreed to be conferred in this Letter of
Transmittal shall survive the death or incapacity of the undersigned and any
obligation of the undersigned hereunder shall be binding upon the heirs,
executors, administrators, personal representatives, trustees in bankruptcy,
legal representatives, successors and assigns of the undersigned.  Tendered Old
Notes may be withdrawn in accordance with Instruction 3 hereto at any time prior
to the Expiration Date.

     THE UNDERSIGNED, BY COMPLETING THE BOX ENTITLED "DESCRIPTION OF OLD NOTES
TENDERED" ABOVE AND SIGNING THIS LETTER, WILL BE DEEMED TO HAVE TENDERED THE OLD
NOTES AS SET FORTH IN SUCH BOX.

                         FORMING PART OF THE TERMS AND
                       CONDITIONS OF THE EXCHANGE OFFER


1.   DELIVERY OF THIS LETTER OF TRANSMITTAL AND CERTIFICATES.

     All physically delivered Old Notes or confirmation of any book-entry
transfer to the Exchange Agent's account at DTC, as well as a properly completed
and duly executed copy of this Letter of Transmittal (or facsimile thereof), and
any other documents required by this Letter of Transmittal, must be received by
the Exchange Agent at any of its addresses set forth herein on or prior to the
Expiration Date.  The method of delivery of this Letter of Transmittal, the Old
Notes and all other required documents is at the election and risk of the
holder.  Instead of delivery by mail, it is recommended that holders use an
overnight or hand delivery service.  Except as otherwise provided below, the
delivery will be deemed made only when actually received by the Exchange Agent.

     Any beneficial holder whose Old Notes are registered in the name of a
broker, dealer, commercial bank, trust company or other nominee and who wishes
to tender Old Notes in the Exchange Offer should contact such registered holder
promptly and instruct such registered holder to tender on such beneficial
holder's behalf.  If such beneficial holder wishes to tender directly, such
beneficial holder must, prior to completing and executing the Letter of
Transmittal and tendering Old Notes, either make appropriate arrangements to
register ownership of the Old Notes in such beneficial holder's own name or
obtain a properly completed bond power from the registered holder.  Beneficial
holders should be aware that the transfer of registered ownership may take
considerable time.

     Delivery to an address other than as set forth herein, or instructions via
a facsimile number other than the ones set forth herein, will not constitute a
valid delivery.

     The Company expressly reserves the right, at any time or from time to time,
to extend the Expiration Date by complying with certain conditions set forth in
the Prospectus.

      LETTERS OF TRANSMITTAL SHOULD NOT BE SENT TO THE COMPANY OR TO DTC.

2.   GUARANTEED DELIVERY PROCEDURES.

     Holders who wish to tender their Old Notes and (i) whose Old Notes are not
immediately available, (ii) who cannot deliver their Old Notes, the Letter of
Transmittal or any other required documents to the Exchange Agent prior to the
Expiration Date or (iii) who cannot complete the procedures for book-entry
transfers on a timely basis, may effect a tender if:

          a.  the tender is made through a member firm of a registered national
     securities exchange or of the National Association of Securities Dealers,
     Inc., a commercial bank or trust company having an office or correspondent
     in the United States or an "eligible guarantor institution" within the
     meaning of Rule 17Ad-15 under the Exchange Act (an "Eligible Institution");

          b.  prior to the Expiration Date, the Exchange Agent receives from
     such holder and the Eligible Institution a properly completed and duly
     executed Notice of Guaranteed Delivery (by facsimile transmission, mail or
     hand delivery) setting forth the name and address of the holder of the Old
     Notes, the certificate or registration number(s) of the tendered Old Notes,
     and the principal amount of Old Notes tendered, stating that the tender is
     being made thereby and guaranteeing that, at least within four (4) New York
     Stock Exchange trading days after the Expiration Date, the tendered Old
     Notes, a duly executed Letter of Transmittal and any other documents
     required by the Letter of Transmittal (or facsimile thereof), will be
     deposited by the Eligible Institution with the Exchange Agent; and

                                      -8-
<PAGE>
 
          c.  such properly completed and executed documents required by the 
     Letter of Transmittal (or facsimile thereof) and tendered Old Notes in
     proper form for transfer (or a confirmation of book-entry transfer of such
     Old Notes into the Exchange Agent's account at DTC) must be received by the
     Exchange Agent at least within four (4) New York Stock Exchange trading
     days after the Expiration Date.

     Any holder who wishes to tender Old Notes pursuant to the guaranteed
delivery procedures described above must ensure that the Exchange Agent receives
the Notice of Guaranteed Delivery relating to such Old Notes prior to the
Expiration Date.  Failure to complete the guaranteed delivery procedures
outlined above will not, of itself, affect the validity or effect a revocation
of any Letter of Transmittal form properly completed and executed by a holder
who attempted to use the guaranteed delivery procedures.

3.   PARTIAL TENDERS; WITHDRAWALS.

     Tenders of Old Notes will be accepted only in integral multiples of $1,000
principal amount at maturity.  If less than the entire principal amount of Old
Notes evidenced by a submitted certificate is tendered, the tendering holder
should fill in the principal amount tendered in the column entitled "Principal
Amount Tendered" of the box entitled "Description of Old Notes Tendered."  A
newly issued Old Note for the principal amount of Old Notes submitted but not
tendered will be sent to such holder, unless the appropriate boxes on this
Letter of Transmittal are completed, as soon as practicable after the Expiration
Date.  All Old Notes delivered to the Exchange Agent will be deemed to have been
tendered in full unless otherwise indicated.

     Any Old Notes tendered pursuant to the Exchange Offer may be withdrawn at
any time prior to the Expiration Date, after which tenders of Old Notes are
irrevocable.  To withdraw a tender of Old Notes in the Exchange Offer, a written
or facsimile transmission notice of withdrawal must be received by the Exchange
Agent by 5:00 p.m., New York City time, on the Expiration Date.  Any such notice
of withdrawal must (i) specify the name of the person having deposited the Old
Notes to be withdrawn (the "Depositor"), (ii) identify the Old Notes to be
withdrawn (including the certificate or registration number(s) and principal
amount of such Old Notes, or, in the case of Old Notes transferred by book-entry
transfer, the name and number of the account at DTC to be credited), (iii) be
signed by the Depositor in the same manner as the original signature on this
Letter of Transmittal (including any required signature guarantees) or be
accompanied by a bond power in the name of the person withdrawing the tender, in
satisfactory form as determined by the Company in its sole discretion, duly
executed by the registered holder, with the signature thereon guaranteed by a
Eligible Institution together with the other documents required upon transfer by
the Indenture, (iv) specify the name in which such Old Notes are to be
registered, if different from that of the Depositor, pursuant to such documents
of transfer, and (v) include a statement that such holder is withdrawing his
election to have such Old Notes exchanged.  All questions as to the validity,
form and eligibility (including time of receipt) of such notices will be
determined by the Company, in its sole discretion, whose determination shall be
final and binding on all parties.  Any Old Notes so withdrawn will be deemed not
to have been validly tendered for purposes of the Exchange Offer and no New
Notes will be issued with respect thereto unless the Old Notes so withdrawn are
validly retendered. Any Old Notes which have been tendered but which are not
accepted for exchange will be returned to the holder thereof without cost to
such holder as promptly as practicable after withdrawal.

4.   SIGNATURE ON THIS LETTER OF TRANSMITTAL; WRITTEN INSTRUMENTS AND
     ENDORSEMENTS; GUARANTEE OF SIGNATURES.

     If this Letter of Transmittal is signed by the registered holder(s) of the
Old Notes tendered hereby, the signature must correspond with the name(s) as
written on the face of the certificates without alteration or enlargement or any
change whatsoever.  If this Letter of Transmittal is signed by a participant in
DTC, the signature must correspond with the name as it appears on the security
position listing as the owner of the Old Notes.

     If any of the Old Notes tendered hereby are owned of record by two or more
joint owners, all such owners must sign this Letter of Transmittal.

                                      -9-
<PAGE>
 
     If a number of Old Notes registered in different names are tendered, it
will be necessary to complete, sign and submit as many separate copies of this
Letter of Transmittal as there are different registrations of Old Notes.

     Signatures on this Letter of Transmittal or a notice of withdrawal, as the
case may be, must be guaranteed by an Eligible Institution unless the Old Notes
tendered hereby are tendered (i) by a registered holder who has not completed
the box entitled "Special Exchange Instructions" or "Special Delivery
Instructions" on the Letter of Transmittal or (ii) for the account of an
Eligible Institution.

     If this Letter of Transmittal is signed by the registered holder or holders
of Old Notes (which term, for the purposes described herein, shall include a
participant in DTC whose name appears on a security listing as the owner of the
Old Notes) listed and tendered hereby, no endorsements of the tendered Old Notes
or separate written instruments of transfer or exchange are required.  In any
other case, the registered holder (or acting holder) must either properly
endorse the Old Notes or transmit properly completed bond powers with this
Letter of Transmittal (in either case executed exactly as the name(s) of the
registered holder(s) appear(s) on the Old Notes, and, with respect to a
participant in DTC whose name appears on a security position listing as the
owner of Old Notes, exactly as the name of the participant appears on such
security position listing), with the signature on the Old Notes or bond power
guaranteed by an Eligible Institution (except where the Old Notes are tendered
for the account of an Eligible Institution).

     If this Letter of Transmittal, any certificates or separate written
instruments of transfer or exchange are signed by trustees, executors,
administrators, guardians, attorneys-in-fact, officers of corporations or others
acting in a fiduciary or representative capacity, such persons should so
indicate when signing, and, unless waived by the Company, proper evidence
satisfactory to the Company of their authority so to act must be submitted.

5.   SPECIAL EXCHANGE AND DELIVERY INSTRUCTIONS.

     Tendering holders should indicate, in the applicable box, the name and
address (or account at DTC) in which the New Notes or Old Notes for principal
amounts not tendered or not accepted for exchange are to be issued and delivered
(or deposited), if different from the names and addresses or accounts of the
person signing this Letter of Transmittal.  In the case of issuance in a
different name, the taxpayer identification number or social security number of
the person named must also be indicated and the tendering holder should complete
the applicable box.

     If no instructions are given, the New Notes (and any Old Notes not tendered
or not accepted) will be issued in the name of and delivered to the acting
holder of the Old Notes or deposited at such holder's account at the Depository.

6.   TRANSFER TAXES.

     The Company shall pay all transfer taxes, if any, applicable to the
exchange of Old Notes pursuant to the Exchange Offer.  If, however, certificates
representing New Notes or Old Notes for principal amounts not tendered or
accepted for exchange are to be delivered to, or are to be registered or issued
in the name of, any person other than the registered holder of the Old Notes
tendered, or if tendered Old Notes are registered in the name of any person
other than the person signing the Letter of Transmittal, or if a transfer tax is
imposed for any reason other than the exchange of Old Notes pursuant to the
Exchanged Offer, then the amount of any such transfer taxes (whether imposed on
the registered holder or any other person) will be payable by the tendering
holder.  If satisfactory evidence of payment of such taxes or exemption
therefrom is not submitted herewith, the amount of such transfer taxes will be
billed directly to such tendering holder.

     Except as provided in this Instruction 6, it will not be necessary for
transfer stamps to be affixed to the Old Notes listed in the Letter of
Transmittal.
    
                                      -10-
<PAGE>
 
7.   WAIVER OF CONDITIONS.

     The Company reserves the absolute right to waive, in whole or in part, any
of the specified conditions to the Exchange Offer set forth in the Prospectus.

8.   MUTILATED, LOST, STOLEN OR DESTROYED NOTES.

     Any holder whose Old Notes have been mutilated, lost, stolen or destroyed
should contact the Exchange Agent at the address indicated above for further
instructions.

9.   REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.

     Questions relating to the procedure for tendering, as well as requests for
additional copies of the Prospectus and this Letter of Transmittal may be
directed to the Exchange Agent at the address and telephone number set forth
above.

10.  VALIDITY AND FORM.

     All questions as to the validity, form, eligibility (including time of
receipt), acceptance of tendered Old Notes and withdrawal of tendered Old Notes
will be determined by the Company in its sole discretion, which determination
will be final and binding.  The Company reserves the absolute right to reject
any and all Old Notes not properly tendered or any Old Notes the Company's
acceptance of which would, in the opinion of counsel for the Company, be
unlawful.  The Company also reserves the absolute right to waive any
irregularities or conditions of tender as to particular Old Notes either before
or after the Expiration Date (including the right to waive the ineligibility of
any holder who seeks to tender Old Notes in the Exchange Offer).  The Company's
interpretation of the terms and conditions of the Exchange Offer (including the
instructions in this Letter of Transmittal) will be final and binding on all
parties.  Unless waived, any defects or irregularities in connection with
tenders of Old Notes must be cured within such time as the Company shall
determine.  Neither the Company, the Exchange Agent nor any other person shall
be under any duty to give notification of defects or irregularities with respect
to tenders of Old Notes, nor shall any of them incur any liability for failure
to give such notification.  Tenders of Old Notes will not be deemed to have been
made until such irregularities have been cured or waived.  Any Old Notes
received by the Exchange Agent that are not properly tendered and as to which
the defects or irregularities have not been cured or waived will be returned
without cost to such holder by the Exchange Agent to the tendering holders of
Old Notes, unless otherwise provided herein, as soon as practicable following
the Expiration Date.

11.  IMPORTANT TAX INFORMATION

     Under U.S. federal income tax law, a holder tendering Old Notes is required
to provide the Exchange Agent with such holder's correct taxpayer identification
number ("TIN") on Substitute Form W-9 above.  If such holder is an individual,
the TIN is the holder's social security number.  The Certificate of Awaiting
Taxpayer Identification Number should be completed if the tendering holder has
not been issued a TIN and has applied for a number or intends to apply for a
number in the near future.  If the Exchange Agent is not provided with the
correct TIN, the holder may be subject to a $50 penalty imposed by the Internal
Revenue Service.  In addition, payments that are made to such holder with
respect to tendered Old Notes may be subject to backup withholding.

     Certain holders (including, among others, all domestic corporations and
certain foreign individuals and foreign entities) are not subject to these
backup withholding and reporting requirements.  Such a holder who satisfies one
or more of the conditions set forth in Part 2 of the Substitute Form W-9 should
execute the certification following such Part 2.  In order for a foreign holder
to qualify as an exempt recipient, that holder must submit to the Exchange Agent
a properly completed Internal Revenue Service Form W-9, signed under penalties
of perjury, attesting to that holder's exempt status.  A copy of such form is
attached to this Letter of Transmittal.
    
                                      -11-
<PAGE>
 
     If backup withholding applies, the Exchange Agent is required to withhold
31% of any amounts otherwise payable to the holder.  Backup withholding is not
an additional tax.  Rather, the tax liability of persons subject to backup
withholding will be reduced by the amount of tax withheld.  If withholding
results in an overpayment of taxes, a refund may be obtained from the Internal
Revenue Service.

     To prevent backup withholding on payments that are made to a holder with
respect to Old Notes tendered for exchange, the holder is required to notify the
Exchange Agent of his or her correct TIN by completing the form herein
certifying that the TIN provided on Substitute Form W-9 is correct (or that such
holder is awaiting a TIN) and that (i) such holder is exempt, (ii) such holder
has not been notified by the Internal Revenue Service that he or she is subject
to backup withholding as a result of failure to report all interest or dividends
or (iii) the Internal Revenue Service has notified such holder that he or she is
no longer subject to backup withholding.

     Each holder is required to give the Exchange Agent the social security
number or employer identification number of the record holder(s) of the Old
Notes.  If Old Notes are in more than one name or are not in the name of the
actual holder, consult the instructions on Internal Revenue Service Form W-9,
which are attached to this Letter of Transmittal, for additional guidance on
which number to report.

     If the tendering holder has not been issued a TIN and has applied for a
number or intends to apply for a number in the near future, write "Applied For"
in the space for the TIN on Substitute Form W-9, sign and date the form and the
Certificate of Awaiting Taxpayer Identification Number and return them to the
Exchange Agent.  If such certificate is completed and the Exchange Agent is not
provided with the TIN within 60 days, the Exchange Agent will withhold  31% of
all payments made thereafter until a TIN is provided to the Exchange Agent.

     IMPORTANT: THIS LETTER OF TRANSMITTAL OR A FACSIMILE THEREOF (TOGETHER WITH
OLD NOTES OR CONFIRMATION OF BOOK-ENTRY TRANSFER AND ALL OTHER REQUIRED
DOCUMENTS) OR A NOTICE OF GUARANTEED DELIVERY MUST BE RECEIVED BY THE EXCHANGE
AGENT ON OR PRIOR TO THE EXPIRATION DATE.

CERTIFICATE OF AWAITING TAXPAYER IDENTIFICATION NUMBER
 
I certify under penalties of perjury that a taxpayer identification number has
not been issued to me, and either (1) I have mailed or delivered an application
to receive a taxpayer identification number to the appropriate Internal Revenue
Service Center or Social Security Administration Office or (2) I intend to mail
or deliver an application in the near future. I understand that if I do not
provide a taxpayer identification number by the time of payment, 31% of all
payments made to me on account of the Exchange Notes shall be retained until I
provide a taxpayer identification number to the Exchange Agent and that, if I do
not provide my taxpayer identification number within 60 days, such retained
amounts shall be remitted to the Internal Revenue Service as backup withholding
and 31% of all reportable payments made to me thereafter will be withheld and
remitted to the Internal Revenue Service until I provide a taxpayer
identification number.

of 1940 U.C. who regularly acts s a broker are exempt.  Payments subject to
reporting under sections 6041 and 6041A are generally exempt from backup
withholding only if made to payees described in items (1) through (7), except a
corporation that provides medical and health care services or bills and collects
payments for such services is not exempt from backup withholding or information
reporting.  Only payees described in items (2) through (6) are exempt from
backup withholding for barter exchange transactions and patronage dividends.

(1)  A corporation.

     retirement plan or custodial account under section 403(b)(7).

  .  Payments to partnerships not engaged in a trade or business in the U.S. and
     which have at least one nonresident partner.
  .  Payment of patronage dividends not paid in money.
  .  Payments made by certain foreign organizations.
  .  Section 404(k) payments made by an ESOP.

Interest payments that are generally exempt from back-up withholding include:

  .  Payments of interest on obligations issued by individuals. Note: You may be
     subject to backup withholding if this interest is $600 or more and is paid
     in the course of the payer's trade or business and you have not provided
     your correct taxpayer identification number to the payer.

  .  Payments of tax-exempt interest (including exempt-interest dividends under
     section 852).

  .  Payments described in section 6049(b)(5) to nonresident aliens.

  .  Payments on tax-free covenant bonds under section 1451.

  .  Payments made by certain foreign organizations.

Exempt payees described above should file Form W-9 to avoid possible erroneous
backup withholding.  FILE THIS FORM WITH THE PAYER.  FURNISH YOUR TAXPAYER
IDENTIFICATION NUMBER.  WRITE "EXEMPT" ON THE FACE OF THE FORM AND RETURN IT TO
THE PAYER.  IF THE PAYMENTS ARE INTEREST, DIVIDENDS, OR PATRONAGE DIVIDENDS,
ALSO SIGN AND DATE THE FORM.

Certain payments other than interest, royalties, and patronage dividends that
are not subject to information reporting are also not subject to backup
withholding.  For details, see the regulations under sections 6041, 6041A(a),
6045, and 6050A.

Privacy Act Notice.  Section 6109 requires most recipients of dividend,
interest, or other payments to give taxpayer identification numbers to payers
who must report the payments to IRS.  IRS uses the numbers for identification
purposes.  Payers must be given the numbers whether or not recipients are
required to file tax returns.  Payers must generally withhold 31% of taxable
interest, dividend, and certain other payments to a payee who does not furnish a
taxpayer identification number to a payer.  Certain penalties may also apply.

Penalties

(1) Penalty for Failure to Furnish Taxpayer Identification Number. If you fail
to furnish your taxpayer identification number to a payer, you are subject to a
penalty of $50 for each such failure unless your failure is due to reasonable
cause and not to willful neglect.

(2) Civil Penalty for False Information with Respect to Withholding. If you make
a false statement with no reasonable basis which results in no imposition of
backup withholding, you are subject to a penalty of $500.

(3)   Criminal Penalty for Falsifying Information.  Willfully falsifying
certifications or affirmations may subject you to criminal penalties including
fines and/or imprisonment.

FOR ADDITIONAL INFORMATION CONTACT YOUR TAX CONSULTANT OR THE INTERNAL REVENUE
SERVICE.
